&lt;hr /&gt;
&lt;div&gt;Although cheap and easy-to-read paperback books and e-books have been widely loved by readers, hardcover books have not been eliminated.&lt;br /&gt;
[[File:hardcover book VS softcover book.jpg|400px]]&lt;br /&gt;
Apart from still only do hardcover classic books. Most hot selling novels will have two versions: paperback and hardcover for choice.&lt;br /&gt;
&lt;br /&gt;
hardcover vs softcover&lt;br /&gt;
&lt;br /&gt;
Why is the publishers willing to do this kind of repetitive &amp;quot;useless work&amp;quot;?&lt;br /&gt;
&lt;br /&gt;
The traditional practice of European and American publishers is to publish new books in three formats at different intervals. The hardcover edition is the first, which is used to attract book fans and customers with more purchasing power.&lt;br /&gt;
&lt;br /&gt;
If the books selling well, then release a paperback version after a period of sales. Then after a period, they will release a mass-market paperback with a smaller format. One-to-one corresponding to readers with different economic abilities, to fully tap the sales potential of a book.&lt;br /&gt;
&lt;br /&gt;
This strategy is also often seen in the film and television industry. For example, movies are always released before they are released on Blu-ray DVD. The income of movie theaters should be greater than the profits of video stores. Even the cost of [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing] will be higher than softcover book printing. But, on average, the profits of publishing hardcover books are higher than publishing paperback books. So they still choose to print hardcover at first.&lt;br /&gt;
&lt;br /&gt;
Movie buffs always want to see movies first in theaters with good acoustics. Just as book collectors want to get their hands on a beautiful hardcover book as soon as possible. From another point of view, libraries also prefer hardcover books. Because hardcover books are easier to preserve.&lt;br /&gt;
&lt;br /&gt;
The publisher's editors are also careful. They will only publish a paperback edition when sales of the hardcover edition have begun to shrink significantly, but demand is relatively high. If a hardcover book is bestselling, publishers often delay releasing a paperback edition. Even if doing so threatens to stifle the book's sales potential.&lt;br /&gt;
&lt;br /&gt;
But, the value of hardcover books is not only reflected in the profit level. A hardcover is a sign of quality. Hardcover is an expression of the publisher's intent to show booksellers, critics, and readers that this is a noteworthy book.&lt;br /&gt;
&lt;br /&gt;
Why do publishers still publish hardcover books at a greater cost?&lt;br /&gt;
&lt;br /&gt;
With competition from more affordable formats such as paperbacks, e-books and audio, will anyone still buy hardbacks?&lt;br /&gt;
&lt;br /&gt;
As things stand, there's no sign of publishers ditching hardbacks: British hardcover novel sales rose 11% in 2017.&lt;br /&gt;
&lt;br /&gt;
When e-books became popular more than a decade ago. Some experts suggested that the format of the book didn't matter. But they are wrong.&lt;br /&gt;
&lt;br /&gt;
A beautiful hardcover book can bring pleasure. It is worth for cherishing, collecting and passing on. Readers will continue to pay for hardcover books, just as some people would rather pay to see a movie in theaters than on TV.&lt;br /&gt;
&lt;br /&gt;
Maybe you will want to ask here, since the sales of hardcover books are still increasing year by year. Why does the entire paper book market still give people the feeling that it is dying?&lt;br /&gt;
&lt;br /&gt;
The answer is that in the era of electronic reading. Perhaps it is more of a war between paperback books and e-books.&lt;br /&gt;
&lt;br /&gt;
The advent of e-books threatens the market for paperbacks, which are closer in both release time and price. It's as if fewer people are buying DVDs, and people are going to watch them on video sites instead.&lt;br /&gt;
&lt;br /&gt;
But hardcover books still have their regular consumer group. Just like the movie theater business doesn't seem to be affected too much.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Nowadays, some paperbacks are not selling as well as hardcovers&amp;quot; said a report in The Economist.&lt;br /&gt;
&lt;br /&gt;
Maybe people should have confidence that in this era. Paperbacks may shrink, but hardcovers and thick books will not die either.&lt;br /&gt;
&lt;br /&gt;
Just like the famous Taiwanese book designer Chen Weishen once put forward. In the future, paper books will have new functions.&lt;br /&gt;
&lt;br /&gt;
Yes, books will exist, but in a different form.&lt;br /&gt;
&lt;br /&gt;
Maybe in the future, our judgment of a book will no longer be some simple abstract words. But the appearance of the whole book, the overall feeling, and the state of holding it in hand.&lt;br /&gt;
&lt;br /&gt;
We have all seen how vinyl records turned into CDs. And now we see that CDs are eliminated and turned into MP3 downloads. But there are always a group of people in the world who want to listen to vinyl, so now record companies are still making vinyl. And only top-level music will anyone be willing to buy vinyl discs. Some people are willing to buy hardback book is not paperback, is the same reason.&lt;/div&gt;</summary>

&lt;hr /&gt;

&lt;br /&gt;
&lt;br /&gt;
how to get a book published ? Both self-published books and publishing houses are common publishing methods. But whether self-publishing your book or published by a publishing house needs to be carefully considered.&lt;br /&gt;
&lt;br /&gt;
In recent years, with the development of the book publishing industry, more and more writers choose to self-publish their own books. According to the latest report from ProQuest affiliate Bowker. Self-publishing grew at a rate of 40 percent in 2018-and shows no signs of slowing down.&lt;br /&gt;
&lt;br /&gt;
What is the difference between self-publishing and publishing house publishing the book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1.The purpose is different.&lt;br /&gt;
&lt;br /&gt;
Self-publishing is often to show academic achievements or to publish more books. Due to the small audience, it is generally only published, not distributed. The main purpose of publishing house is to make a profit, not only to publish but also to distribute.&lt;br /&gt;
&lt;br /&gt;
2.Copyright ownership is different.&lt;br /&gt;
&lt;br /&gt;
Publish the book at your own expense, and the copyright belongs to the individual (author). Publishers publishing the book is a partnership between authors and publishers. But the copyright belongs to the publishing house. And after publishing the book, the publisher pays the author.&lt;br /&gt;
&lt;br /&gt;
3.The requirements for publishing books are different.&lt;br /&gt;
&lt;br /&gt;
The requirements for self-published books are not as high as those published by publishers. Self-published books are sufficient as long as the content conforms to the publishing regulations. However, the publishing house not only needs to meet the requirements of the publishing regulations. But also needs a relatively high market prospect.&lt;br /&gt;
&lt;br /&gt;
4.The cycle is different.&lt;br /&gt;
&lt;br /&gt;
The process of self-publish is simple and the cycle is short. Authors can choose to cooperate with agency companies without spending a lot of time and energy. They only need to deliver the manuscripts that are in order, clear, and finalized to the agency company. The agency company can provide one-stop publishing and distribution services to help authors quickly and efficiently write books and save money. Publishing costs. Publishers have their own book review cycle, and it takes a long time. If the interpersonal relationship is not handled well, the content of the manuscript is not very innovative and the author is unknown, it is difficult to publish the book at public expense by the publishing house.&lt;br /&gt;
&lt;br /&gt;
5.The cost bearers are different.&lt;br /&gt;
&lt;br /&gt;
Self-publishing the book: all the [https://mail.google.com/mail/u/0/?fs=1&amp;amp;tf=cm&amp;amp;source=mailto&amp;amp;to=Quote@chinaprinting4u.com cost of self publishing a book] is borne by the individual.&lt;br /&gt;
&lt;br /&gt;
Publishing house publish the book: The cost shall be borne by the publisher. Publishing houses are mainly aimed at authors who are famous in various fields, or have a certain mass base, or books that can sell well in the market. Because the publishing house bears the cost to the author to publish the book, it is to profit. So they only publish some books that have a certain market for free. But, the general author publishes books, their reading crowd is very small. So the publishing house will not publish some new authors‘book and new works for free. Thus, our common publishing method is that the author publishes at his own expense.&lt;br /&gt;
&lt;br /&gt;
6.The printing method is different.&lt;br /&gt;
&lt;br /&gt;
Self-publishing is find a book printer to print your book. The publishing house printing the book, it is the printing company entrusted by the publishing house to print in batches.&lt;br /&gt;
&lt;br /&gt;
Why more and more people choose self-publish their book&lt;br /&gt;
&lt;br /&gt;
&amp;quot;The self-publishing landscape continues to improve, creating more and more opportunities for authors to manage their own path through the process,&amp;quot; said Beat Barblan, Vice President of Publishing and Data Services at Bowker and chairman of the board of the International ISBN Agency. &amp;quot;As more authors take advantage of the abundant tools now available to publish, distribute and market their own books, we expect that self-publishing will continue to grow at a steady pace.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Is self-publishing better than publisher publishing the book?&lt;br /&gt;
&lt;br /&gt;
Whether self-published or published by a publisher, each has its own benefits. If your book had been popular online, choose cooperate with a publisher is a good choice. Why? Because the publisher have strong financial and network support, you cooperate with them. Not only is it beneficial to improve the popularity of the work, but also you don't need to pay any cost to publish your book. If you only want to publish your book show academic achievements, it is suitable for self-publishing. Because this kind of works have small audience, it is hard to published by publishers.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;Za '''elektronické publikování''' lze považovat v podstatě jakékoliv zpřístupňovaní dokumentů v elektronické (digitální) podobě určitému okruhu uživatelů. Jako u klasického publikování předchází vydání řada přípravných (produkčních) kroků v podobě tvorby, zachycení, transformace i ukládání a diseminace dokumentů.&amp;lt;ref name=&amp;quot;Elektronické publikování&amp;quot;&amp;gt; [http://ikaros.cz/elektronicke-publikovani Elektronické publikování]. [online]. [cit. 2016-11-10].&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Proces a přenos elektronického publikování==&lt;br /&gt;
&lt;br /&gt;
Z procesu vyplývá, že elektronické publikování '''začíná jako''' činnost, kterou mnozí z nás považují již za zcela samozřejmou součást své práce: '''tvorba dokumentů''' s využitím kancelářské výpočetní techniky. Pokud jsou výsledky této činnosti zpřístupněny určité skupině uživatelů, například v rámci výzkumných týmů v podnikovém intranetu, lokální síti nebo i síti globální, pak se skutečně jedná o jistou formu elektronického publikování. Výzkumné nebo pracovní týmy totiž mohou zveřejnit/publikovat výsledky své práce (report, odborná stať, tabulky statistických dat, databáze) tak, '''aby tyto dokumenty byly přístupné''' pouze určité skupině uživatelů '''v rámci dané sítě'''.&lt;br /&gt;
&lt;br /&gt;
Navíc je přenos informací elektronickou cestou rychlý a má díky celosvětové počítačové síti široký (globální) dosah a také většina informačních zdrojů je k dispozici v elektronické podobě. Proto elektronické publikování proniklo téměř do všech oblastí lidské činnosti - s elektronickými publikacemi se můžeme setkat v oblasti komerce (e-business, e-banking), vědy, kultury, umění, státní správy (e-demokracie, e-goverment) i vzdělávání (e-learning), ale nesmíme zapomenout ani na oblast běžné komunikace - elektronickou poštu (e-mail).&amp;lt;ref name=&amp;quot;Elektronické publikování a XML&amp;quot;&amp;gt; [http://old.gis.zcu.cz/studium/Materialy_text/publikovani.pdf Elektronické publikování a XML]. [online]. [cit. 2016-11-10].&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Historie elektronického publikování==&lt;br /&gt;
&lt;br /&gt;
Než světlo světa spatřila první elektronická kniha a mohl být odstartován proces elektronického publikování, mělo před sebou lidstvo několik zásadních objevů, které jak jinak začalo [https://cs.wikipedia.org/wiki/P%C3%ADsmo ''objevem písma''] (4 500 let před naším letopočtem), následně ''úpravou dokumentů'', kdy v průběhu 12. století došlo k oddělení slov a odstavců, až po revoluci nejznámější, [[Johannes Gutenberg|Gutenbergovu]], která vizuální podobu textu (neboli harmonizaci písmoobrazu) dovedla k ''mechanické dokonalosti''.&lt;br /&gt;
&lt;br /&gt;
Po Guttenbergově revoluci se rovněž začal rozšiřovat tzv. ''&amp;quot;individuální tisk&amp;quot;'', kam můžeme řadit psací stroje; rozvíjelo se také písemnictví v institucích, jako např. tiskárny, knihovny a univerzity. A pak přišel [https://cs.wikipedia.org/wiki/Gottfried_Wilhelm_Leibniz Leibnitz] s binárním systémem jedniček a nul a s ním i '''koncept digitalizace''', který poprvé představil ve svém článku z roku 1705 (kde také zmínil čtyři základní systémy: sčítaní, odečítání, násobení a dělení); dalších 20 let se pak věnoval vývoji mechanického počítače. Významnější pokrok ale přinesl až informatik [[Alan Turing|Alan Turing]]. Ten se věnoval například otázce rozhodování (jestli dokážeme vše spočítat; tj. popsat pomoci formálních matematických algoritmů) a vymyslel matematický stroj &amp;quot;turing machine&amp;quot;, který ale nikdy nepostavil.&lt;br /&gt;
&lt;br /&gt;
Každopádně vývoj pokračoval dál a ve '''40. letech vznikly první počítače''', objevila se myš, kterou vymyslel [https://cs.wikipedia.org/wiki/Douglas_Engelbart Douglas Engelbart] a samozřejmě [[World Wide Web|World Wide Web]], který představil Tim Berners-Lee. Nicméně '''koncept moderních počítačů, internetu a sociálního čtení''' představil de facto již v roce 1945 [[Vannevar Bush|Vannevar Bush]], ve svém konceptu [[Memex|Memex]]. Zajímavé možnosti, jak by se dal počítač využít pro &amp;quot;normální lidi&amp;quot;, představil i již zmiňovaný Douglas Englebart ve svém příspěvku v prosinci roku 1968, ale tehdy ještě předběhl svou dobu; počítače byly obrovské, stály miliony dolarů a používali je takřka výhradně jen vědci a armáda.&amp;lt;ref name=&amp;quot;Čtení a zprostředkování literatury v digitálním věku&amp;quot;&amp;gt; [http://ikaros.cz/cteni-a-zprostredkovani-literatury-v-digitalnim-veku Čtení a zprostředkování literatury v digitálním věku]. [online]. [cit. 2016-11-10].&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Až následkem všech těchto událostí/vynálezů mohl [https://cs.wikipedia.org/wiki/Michael_S._Hart Michael S. Hart] vytvořit první [[Elektronická kniha|elektronickou knihu]] v podobě Deklarace nezávislosti Spojených států.&lt;br /&gt;

==Elektronická publikace==&lt;br /&gt;
&lt;br /&gt;
Pojem [[Elektronická kniha|elektronická kniha]] (eBook) se nejčastěji používá pro označení digitálního ekvivalentu tištěné publikace. Tímto pojmem bývají označovány různé souborové formáty publikací, a to jak zcela obecné, tak i speciálně určené právě pro čtečky elektronických publikací. Jako elektronická kniha může být rovněž označena publikace elektronicky dostupná prostřednictvím internetu.&lt;br /&gt;
&lt;br /&gt;
Dříve byly vyhotovovány elektronické knihy především ve formátech .txt, .htm, .html, .chm, .pdf, .ps, .lit, .pdb, .prc, .mobi,.epub, .azw, .opf, .tr2, .tr3, pkg, .ceb, .xeb, bin, .lbr, lrf .lrx, .pdf, .dnl, .exe, .djvu, .xml, .fb2, dtb, aeh ale i mnohé další. Nyní je nejrozšířenějším formátem HTML5 a to kvůli jeho interaktivním možnostem, jenž lze nejvíce uplatnit v didaktické literatuře.&lt;br /&gt;
Množství formátů odpovídá fázi vývoje technologií. Podobně tomu bylo například u videa i fotografií. Z velkého množství formátů se stal nejrozšířenějším MPEG a JPEG. Dnes se automaticky předpokládá, že si uživatelé zasílají fotografie ve formátu JPEG (.jpg), přestože stále existuje řada formátů používaných v IT.&amp;lt;ref name=&amp;quot;eBook&amp;quot;&amp;gt; [http://www.soubosonohy.cz/files/Petr%20Foto%20/manual_web.pdf MANUÁL PRO PRÁCI S ELEKTRONICKÝMI UČEBNICEMI].

&lt;br /&gt;
==Elektronický self-publishing==&lt;br /&gt;
&lt;br /&gt;
Zavedených a často používaných platforem pro self-publishing&amp;lt;ref name=&amp;quot;self-publishing&amp;quot;&amp;gt; [http://www.inflow.cz/platformy-pro-elektronicky-self-publishing-charakteristiky-srovnani-1-cast Platformy pro elektronický self-publishing]. [online]. [cit. 2016-11-10].&amp;lt;/ref&amp;gt; dnes existuje poměrně velké množství. Všechny však poskytují jednu základní funkci, a to možnost autorovi vydat a šířit knihu bez pomoci nakladatele. V mnoha ohledech se však od sebe odlišují a pro různé autory nejsou stejně vhodné. Existují tři základní možnosti, jak vydat e-knihu bez nakladatele:&lt;br /&gt;
&lt;br /&gt;
*Vydávání mimo platformy (zveřejnění knihy v (1) textových či (2) specializovaných formátech)&lt;br /&gt;
*Vydávání na nezávislých platformách&lt;br /&gt;
*Vydávání na platformách velkých společností&lt;br /&gt;
&lt;br /&gt;
Každý ze způsobů vydání e-knihy s sebou nese specifické požadavky na autora a zahrnuje jistá pozitiva i negativa. Celosvětově nejběžnější metodou elektronického self-publishingu je dnes používání publikačních platforem.&lt;br /&gt;
&lt;br /&gt;
===Vydávání na nezávislých platformách:===&lt;br /&gt;
&lt;br /&gt;
Níže uvedené publikační platformy představují služby, které jsou široce používané nebo nějakým způsobem významné. Jejich výčet však rozhodně není úplný. Elektronický self-publishing, tedy vydávání bez nakladatelů, se v současnosti velmi rychle vyvíjí a nové aplikace a nástroje v této oblasti rychle přibývají. Platformy zastoupené níže nicméně reprezentují všeobecně respektovaný základ, s nímž se nějakým způsobem setkává většina autorů v západním světě&amp;lt;ref name=&amp;quot;Elektronický self-publishing&amp;quot;&amp;gt; [http://www.inflow.cz/platformy-pro-elektronicky-self-publishing-charakteristiky-srovnani-2-cast Platformy pro elektronický self-publishing].

&lt;br /&gt;
Smashwords je v současnosti jedním z největších globálních vydavatelů a distributorů e-knih nezávislých autorů. Založil ho Mark Coker, známý podnikatel a vizionář na poli nezávislého publikování v roce 2008. Smashwords v současné době představuje po Kindle Direct Publishing pravděpodobně druhou nejznámější publikační platformu.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Společnost Lulu byla založena v roce 2002 a do současnosti vydala přes milion 700 tisíc titulů. Je tedy jednou z nejstarších publikačních platforem vůbec. S přibývající konkurencí její popularita klesá, stále však patří mezi nejčastěji využívané nástroje pro nezávislé autory.&lt;br /&gt;

Publi.cz je elektronický multiplatformní publikační systém, jenž vychází z koncepce eMUNI, který vyvinula Masarykova univerzita ve spolupráci se společností Code Creator. Ačkoliv tuto platformu zpočátku využívaly především univerzity (eMUNI, eCUNI, eUPOL, eCVUT, eOSU, eTUL apod.) společně se středním odborným školstvím, nyní se začíná hojně využívat i v nakladatelské sféře. Její velkou devízou pro autory je možnost vytvářet interaktivní výukové materiály na rozdíl od distribuce prostých PDF dokumentů.&lt;br /&gt;

Sellfy je platforma pro distribuci digitálního obsahu; e-knihy jsou tedy jen jedním z více druhů médií, které lze s pomocí Sellfy poskytovat zákazníkům. Mezi službami, které v tomto článku představuji, je Sellfy výjimečná a poněkud odlišná. Není to typická platforma pro tvorbu e-knih, ale spíše nástroj, který zjednodušuje celý proces vydání, distribuce, plateb, marketingu a dalších prvků, z nichž poskytování e-knih sestává.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Kindle Direct Publishing (KDP) je dnes pravděpodobně nejpoužívanějším systémem pro elektronické vydávání bez nakladatelů. Pochází od společnosti Amazon, která ho spustila v roce 2007 - tedy ve stejném roce, kdy se začal vyrábět Kindle první generace. KDP je díky svému rozšíření a účinnému marketingu pro americké nezávislé autory často první volbou při vydávání e-knihy. Stojí-li autor o komerční úspěch nebo o rozšíření knihy mezi co nejširší skupinu čtenářů, musí - minimálně na americkém trhu - kromě jiných platforem použít právě Kindle Direct Publishing.&lt;br /&gt;

NOOK Press je publikační platforma vyvíjená společností Barnes &amp;amp; Noble od roku 2013; je nástupkyní zrušené platformy PubIt!, ale v různých ohledech na ni navazuje. Při vývoji NOOK Press byly zohledněny názory a připomínky autorů publikujících na PubIt!; byly také využity některé funkce poskytované publikační platformou FastPencil, s níž Barnes &amp;amp; Noble spolupracuje. Záměrem B&amp;amp;N je vytvořit nástroj jak pro americký, tak mezinárodní trh: v současnosti je NOOK Press oficiálně použitelný a podporovaný také v několika evropských zemích.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;
== How to choose the paper for your printing project? ==&lt;br /&gt;
&lt;br /&gt;
In '''China printing service'''[https://www.chinaprinting4u.com/ china printing service],select the paper for your printing project is one of the most important parts,which will directly affect the final presentation and the cost of your printed products. &lt;br /&gt;
&lt;br /&gt;
Our commonly used printing paper can be divided into the following night Categories：White cardboard, gray board, coated paper, offset paper, corrugated paper, specialty paper, writing paper, Kraft paper, newsprint,etc. &lt;br /&gt;
&lt;br /&gt;
1. White cardboard:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
It is a kind of thick, thick and heavy paper. The surface of this paper is smooth and calendered with high stiffness. &lt;br /&gt;
&lt;br /&gt;
Characteristics: Single-layer or multi-layer combined paper made entirely by bleached chemical pulping and fully sizing, generally the basis weight is above 150g/�? The characteristics of this cardboard are: high smoothness, good stiffness, neat appearance and good formation. &lt;br /&gt;
&lt;br /&gt;
Common weights: white cardboard weights of 200, 250, 300, 350, 400 grams are more commonly used. &lt;br /&gt;
&lt;br /&gt;
Advantages: thick enough and hard enough. The hardness of the cardboard is very high among the paper of the same number of grams. People who like thick cards will really appreciate this paper.

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;br /&gt;

== Why Use Light Paper For Children Book Printing ==&lt;br /&gt;
&lt;br /&gt;
Because young children like to chew on objects, publishing houses and [https://www.chinaprinting4u.com/Children_Book_51.htm children’s book printers] mostly use environmentally friendly materials to print children's books. Eco-friendly printing has also become a major trend in the development of the entire children’s book printing industry. Due to its light weight and low price, light paper has become a new choice for children's book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What’s light paper? &lt;br /&gt;
&lt;br /&gt;
Light paper is light offset paper, which is a more eco-friendly paper. The transliteration of light paper is called Munkedal in Sweden. The light paper produced by a local paper company is also called Munkedal. When this paper was first introduced to China, it called &amp;quot; Monken&amp;quot; . Since it is the earliest light offset paper introduced in China, this type of paper is now habitually called Mengken paper (lightweight paper) in China.

&lt;br /&gt;
Check out the following introduction to find the answer&lt;br /&gt;
&lt;br /&gt;
1. Light paper has better printing effect and lower cost than double offset paper. The price of light paper is lower than coated paper and double-coated paper, so the cost pressure of the publishing house will be less. The bulk of lightweight paper is very good, so this paper can replace the original high basis weight paper with the same thickness, thereby saving shipping cost.&lt;br /&gt;
&lt;br /&gt;
2. The color is natural. Lightweight paper is made of chemical pulp without fluorescent whitening agent. It is milky white or light beige due to the addition of special dyes.

&lt;br /&gt;
4. The paper has a long life and is environmentally friendly. Lightweight paper is chlorine-free paper, made of 100% pure chemical pulp, and does not contain components such as fluorescent whitening agents, so that the paper is slightly alkaline and can be stored for thousands of years without deterioration. Lightweight paper is not coated, mainly composed of fiber, calcium carbonate and water, does not pollute the environment, which is a eco-friendly paper.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;

&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;br /&gt;
&lt;br /&gt;
== What does your hardcover book look like ==&lt;br /&gt;
&lt;br /&gt;
Why do readers expect to receive a printed hardcover book?&lt;br /&gt;
&lt;br /&gt;
Have you ever wondered what expectations customers will have when they are buying a hardcover book online? And nowadays, online shopping is widely carried out, but readers can't touch the book they are interested in if they buy a book online. So, how will they judge what the book they buy is most likely to look like?&lt;br /&gt;
&lt;br /&gt;
Undoubtedly, readers choose to buy a collectible printed hardcover book because they want to return to more essential and comfortable reading.&lt;br /&gt;
&lt;br /&gt;
So, regardless of the content of the text, how do the different [https://www.chinaprinting4u.com/ book printing] design affecting the reading experience, and what does the bookbinding means for a high-quality hardcover book printing? This time, let's briefly understand the knowledge related to the &amp;quot;book&amp;quot; itself.&lt;br /&gt;
&lt;br /&gt;
[[File:_DSC0493.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What is the difference between paperback book and hardcover book?&lt;br /&gt;
&lt;br /&gt;
For book printing in China, paperback book printing is basically used art paper in cover and perfect binding. The hardcover book printing is basically used board paper in cover and thread binding.&lt;br /&gt;
&lt;br /&gt;
The book printing design decides the hardcover book printing ways and their eventually appear; the bookbinding is an important part of the book printing design; the paperback and hardcover both are the bookbinding concept.&lt;br /&gt;
&lt;br /&gt;
According to the book printing company, paperback and hardcover can be identified by the book cover paper. Furthermore, the cover also can decide the binding ways for the book printing.&lt;br /&gt;

According to the regulations of the industry standard QB323-80, the main technical indicators of the rice cardboard are: the tightness is not more than 0.85g/cubic meter; the breaking length (average length and width) is not less than 2200m; the folding endurance (reciprocating times) is not less than 10 horizontally. The sizing degree is not less than 1.5mm; the ash content is 5.0% to 8.0%; the lateral stretchability is not more than 2.5%.&lt;br /&gt;

== Coated VS Special Paper:What’s The Difference ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Book_Printing_32.htm Printing books in china], paper is one of the four major elements, so select the paper for printed products is very important. The choice of paper has a great influence on the color reproduction, stiffness, artistic effect and grade of the books. The common paper for book printing is coated paper and special paper, so what is the difference between the two? &lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Coated paper, also known as coated printing paper, is called powder paper in Hong Kong and other regions. It is a printing paper made of base paper coated with white paint. Mainly used for printing book covers and illustrations, color pictures, various commodity advertisements, samples, commodity packaging, trademarks, etc. &lt;br /&gt;
&lt;br /&gt;
Classification of coated paper&lt;br /&gt;
&lt;br /&gt;
1. Double-sided &lt;br /&gt;
&lt;br /&gt;
The paper surface is smooth and white on both sides, with good gloss and high opacity. After color printing, the pattern effect is bright and color gradation is good, which is suitable for [https://www.chinaprinting4u.com/Book_Printing_32.htm custom coloring book printing].&lt;br /&gt;
&lt;br /&gt;
 2. One-sided&lt;br /&gt;
&lt;br /&gt;
 One side is coated and the other side is glued, so the paper is bright, smooth, and uniform in ink absorption on one side. Suitable for printing labels, posters, covers, etc.&lt;br /&gt;
&lt;br /&gt;
 What is specialty paper?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
There are different definitions of special paper in the market. In layman's terms, it refers to paper that is different from common coated paper, matte paper, writing paper, Carbonless paper, gray cardboard and other ordinary paper, Special paper has the following characteristics: &lt;br /&gt;
&lt;br /&gt;
1. Use special raw materials &lt;br /&gt;
&lt;br /&gt;
Specialty paper is a paper with special functions made of different fibers by a paper machine. For example, synthetic fibers, synthetic pulp or mixed wood pulp and other raw materials are used alone, and different materials are used for modification or processing.&lt;br /&gt;
&lt;br /&gt;
2. For special purpose &lt;br /&gt;
&lt;br /&gt;
Due to the use of special raw materials, paper is endowed with special functions and uses, such as: life, building materials, electrical products, filters, machinery industry, agriculture, information, optics, culture and art, biochemical cutting-edge technology, etc. &lt;br /&gt;
&lt;br /&gt;
In short, as long as special raw materials or paper materials for special purposes are used, they are collectively referred to as special paper. &lt;br /&gt;
&lt;br /&gt;
The difference between coated and special paper &lt;br /&gt;
&lt;br /&gt;
Coated paper is the cover paper of magazines, leaflets,book, etc. that are usually used. It is very common and can be seen everywhere. &lt;br /&gt;
&lt;br /&gt;
The advantage of coated paper: &lt;br /&gt;
&lt;br /&gt;
The price is cheap, the color reproduction is good, and the thickness is moderate.&lt;br /&gt;
&lt;br /&gt;
 The shortcoming of coated paper:&lt;br /&gt;
&lt;br /&gt;
 1. No grade and very common.&lt;br /&gt;
&lt;br /&gt;
 2. Folding is in an air-dry environment, especially in winter, it is easy to burst and crack.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. Ordinary coated paper is not enough stiffness, relatively soft, and obviously not comfortable to use.&lt;br /&gt;
&lt;br /&gt;
 The advantage of special paper: &lt;br /&gt;
&lt;br /&gt;
1.Special paper is better than coated paper in paper properties. Such as bulk, stiffness and color reproduction. About 250 grams of special paper can achieve the effect of 300 grams of coated paper.&lt;br /&gt;
&lt;br /&gt;
 2.Special paper feels comfortable, and books and brochures are not easy to make readers tired.&lt;br /&gt;
&lt;br /&gt;
 3.It is widely used in various high-grade printed materials, such as business cards, picture albums, magazines, commemorative albums, invitations,hardcover book printing and etc.&lt;br /&gt;
&lt;br /&gt;
 The shortcoming of special paper: The price is quite expensive.&lt;br /&gt;
&lt;br /&gt;
 In short,different papers have different properties that determine what they can be used for.&lt;br /&gt;

Thread binding should choose a slightly thinner paper with a softer texture. The position of punching holes and the way of threading can also be creatively changed according to needs, so that the catalog design not only retains the traditional characteristics of the threading process, but also has a modern and fashionable sense.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Classification of printing methods, which can be divided into:&lt;br /&gt;
 (1) offset printing, that is, lithographic printing, which is printed on a flat surface, such as paper and self-adhesive;&lt;br /&gt;
(2) Embossed printing, also called flexo printing, is generally used in plastic printing;&lt;br /&gt;
(3) Screen printing, which is what we call universal printing, it can be printed on any object and is very flexible, but it has a disadvantage that it is not suitable for large-scale printing.&lt;br /&gt;
Part 2 : How to classify printing paper?&lt;br /&gt;
&lt;br /&gt;
Commonly used paper for China printing Paper can be divided into industrial paper, packaging paper, household paper, cultural paper, etc. according to different uses, among which cultural paper includes writing paper, art drawing paper, printing paper, etc. .&lt;br /&gt;
In the printing paper, according to the performance and characteristics of the paper, it is divided into newsprint, letterpress printing paper, offset printing coated paper, dictionary paper, map and marine drawings, gravure printing paper, painting newspaper, weekly newspaper, whiteboard paper, writing paper, etc. . In addition, some high-end prints also widely use art drawing paper.&lt;br /&gt;
coated paper&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;

Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;br /&gt;
&lt;br /&gt;
== What does your hardcover book look like ==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[[File:_DSC0493.JPG|400px]]&lt;br /&gt;

&lt;br /&gt;
For book printing in China, paperback book printing is basically used art paper in cover and perfect binding. The hardcover book printing is basically used board paper in cover and thread binding.&lt;br /&gt;

&lt;br /&gt;
In addition to the cover of the book itself, no matter paperback or hardcover for book printing, the outer layer of the book is usually covered with a protective cover. The following is a hardcover book to introduce the structure of each part of the book.&lt;br /&gt;
&lt;br /&gt;
This is the basic structure of hardcover book, which can be found in [https://www.chinaprinting4u.com/Hardcover_Book_50.htm hardcover book printing]. The paperback book differs in the composition of the cover and the end paper.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
In book printing china, end paper generally use for custom books and picture albums. Different type of books,the end paper is different.Select the right end paper will Enhance the temperament of the book.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What’s end paper?&lt;br /&gt;
&lt;br /&gt;
End paper is the layer of paper between the cover and the text. Refers to the front and back (or top and bottom) of the custom hardcover book block, each with a folded 2-page white or colored paper. End paper has two functions, one is to protect the book block from being dirty and damaged; the other is to firmly connect with the book cover.&lt;br /&gt;
&lt;br /&gt;
Such as end paper design of the hardcover book is very particular. End paper design arrangements: the use of abstract texture effects, illustrations, patterns.,also useful for photo performance. Its style and content are consistent with the book cover as a whole. But the color has to change relative to the cover. Generally need to be more elegant. The graphic contrast is relatively weak. Some can be decorated with square continuous patterns, produce visual effect. Visually produce a transition from the cover to the heart.&lt;br /&gt;
&lt;br /&gt;
3 types of end paper for book printing &lt;br /&gt;
Papers commonly used as end paper include offset paper, coated paper, card paper.&lt;br /&gt;
Offset paper is mostly white as end paper. Different grades of books use different quantification of end paper. For paperback book printing, the ration is 60-150g/square meter, and for higher-grade books and picture book printing, the ration is 200-250g/square meter. To avoid wrinkling when pasting, the thread direction of the end paper should be parallel to the spine of the book.&lt;br /&gt;
&lt;br /&gt;
Coated paper is used as a end paper for higher-grade books, and the ration is generally between 100 and 250g/square meter. Decorative patterns related to the content of the book can also be printed to increase the decorative effect of books.&lt;br /&gt;
&lt;br /&gt;

According to the regulations of the industry standard QB323-80, the main technical indicators of the rice cardboard are: the tightness is not more than 0.85g/cubic meter; the breaking length (average length and width) is not less than 2200m; the folding endurance (reciprocating times) is not less than 10 horizontally. The sizing degree is not less than 1.5mm; the ash content is 5.0% to 8.0%; the lateral stretchability is not more than 2.5%.&lt;br /&gt;
&lt;br /&gt;
== Coated VS Special Paper:What’s The Difference ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Book_Printing_32.htm Printing books in china], paper is one of the four major elements, so select the paper for printed products is very important. The choice of paper has a great influence on the color reproduction, stiffness, artistic effect and grade of the books. The common paper for book printing is coated paper and special paper, so what is the difference between the two? &lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Coated paper, also known as coated printing paper, is called powder paper in Hong Kong and other regions. It is a printing paper made of base paper coated with white paint. Mainly used for printing book covers and illustrations, color pictures, various commodity advertisements, samples, commodity packaging, trademarks, etc. &lt;br /&gt;
&lt;br /&gt;
Classification of coated paper&lt;br /&gt;
&lt;br /&gt;
1. Double-sided &lt;br /&gt;
&lt;br /&gt;
The paper surface is smooth and white on both sides, with good gloss and high opacity. After color printing, the pattern effect is bright and color gradation is good, which is suitable for [https://www.chinaprinting4u.com/Book_Printing_32.htm custom coloring book printing].&lt;br /&gt;
&lt;br /&gt;
 2. One-sided&lt;br /&gt;
&lt;br /&gt;
 One side is coated and the other side is glued, so the paper is bright, smooth, and uniform in ink absorption on one side. Suitable for printing labels, posters, covers, etc.&lt;br /&gt;
&lt;br /&gt;
 What is specialty paper?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
There are different definitions of special paper in the market. In layman's terms, it refers to paper that is different from common coated paper, matte paper, writing paper, Carbonless paper, gray cardboard and other ordinary paper, Special paper has the following characteristics: &lt;br /&gt;
&lt;br /&gt;
1. Use special raw materials &lt;br /&gt;
&lt;br /&gt;
Specialty paper is a paper with special functions made of different fibers by a paper machine. For example, synthetic fibers, synthetic pulp or mixed wood pulp and other raw materials are used alone, and different materials are used for modification or processing.&lt;br /&gt;
&lt;br /&gt;
2. For special purpose &lt;br /&gt;
&lt;br /&gt;
Due to the use of special raw materials, paper is endowed with special functions and uses, such as: life, building materials, electrical products, filters, machinery industry, agriculture, information, optics, culture and art, biochemical cutting-edge technology, etc. &lt;br /&gt;
&lt;br /&gt;
In short, as long as special raw materials or paper materials for special purposes are used, they are collectively referred to as special paper. &lt;br /&gt;
&lt;br /&gt;
The difference between coated and special paper &lt;br /&gt;
&lt;br /&gt;
Coated paper is the cover paper of magazines, leaflets,book, etc. that are usually used. It is very common and can be seen everywhere. &lt;br /&gt;
&lt;br /&gt;
The advantage of coated paper: &lt;br /&gt;
&lt;br /&gt;
The price is cheap, the color reproduction is good, and the thickness is moderate.&lt;br /&gt;
&lt;br /&gt;
 The shortcoming of coated paper:&lt;br /&gt;
&lt;br /&gt;
 1. No grade and very common.&lt;br /&gt;
&lt;br /&gt;
 2. Folding is in an air-dry environment, especially in winter, it is easy to burst and crack.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. Ordinary coated paper is not enough stiffness, relatively soft, and obviously not comfortable to use.&lt;br /&gt;
&lt;br /&gt;
 The advantage of special paper: &lt;br /&gt;
&lt;br /&gt;
1.Special paper is better than coated paper in paper properties. Such as bulk, stiffness and color reproduction. About 250 grams of special paper can achieve the effect of 300 grams of coated paper.&lt;br /&gt;
&lt;br /&gt;
 2.Special paper feels comfortable, and books and brochures are not easy to make readers tired.&lt;br /&gt;
&lt;br /&gt;
 3.It is widely used in various high-grade printed materials, such as business cards, picture albums, magazines, commemorative albums, invitations,hardcover book printing and etc.&lt;br /&gt;
&lt;br /&gt;
 The shortcoming of special paper: The price is quite expensive.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;

  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;

== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;br /&gt;
&lt;br /&gt;
== What does your hardcover book look like ==&lt;br /&gt;
&lt;br /&gt;
Why do readers expect to receive a printed hardcover book?&lt;br /&gt;

And nowadays, online shopping is widely carried out, but readers can't touch the book they are interested in if they buy a book online. So, how will they judge what the book they buy is most likely to look like?&lt;br /&gt;

This time, let's briefly understand the knowledge related to the &amp;quot;book&amp;quot; itself.&lt;br /&gt;
&lt;br /&gt;
[[File:_DSC0493.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What is the difference between paperback book and hardcover book?&lt;br /&gt;
&lt;br /&gt;
For book printing in China, paperback book printing is basically used art paper in cover and perfect binding. The hardcover book printing is basically used board paper in cover and thread binding.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
According to the book printing company, paperback and hardcover can be identified by the book cover paper. Furthermore, the cover also can decide the binding ways for the book printing.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The structure of the hardcover book&lt;br /&gt;
&lt;br /&gt;
In addition to the cover of the book itself, no matter paperback or hardcover for book printing, the outer layer of the book is usually covered with a protective cover. The following is a hardcover book to introduce the structure of each part of the book.&lt;br /&gt;
&lt;br /&gt;
This is the basic structure of hardcover book, which can be found in [https://www.chinaprinting4u.com/Hardcover_Book_50.htm hardcover book printing]. The paperback book differs in the composition of the cover and the end paper.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
In book printing china, end paper generally use for custom books and picture albums. Different type of books,the end paper is different.Select the right end paper will Enhance the temperament of the book.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What’s end paper?&lt;br /&gt;
&lt;br /&gt;
End paper is the layer of paper between the cover and the text. Refers to the front and back (or top and bottom) of the custom hardcover book block, each with a folded 2-page white or colored paper. End paper has two functions, one is to protect the book block from being dirty and damaged; the other is to firmly connect with the book cover.&lt;br /&gt;
&lt;br /&gt;
Such as end paper design of the hardcover book is very particular. End paper design arrangements: the use of abstract texture effects, illustrations, patterns.,also useful for photo performance. Its style and content are consistent with the book cover as a whole. But the color has to change relative to the cover. Generally need to be more elegant. The graphic contrast is relatively weak. Some can be decorated with square continuous patterns, produce visual effect. Visually produce a transition from the cover to the heart.&lt;br /&gt;
&lt;br /&gt;
3 types of end paper for book printing &lt;br /&gt;
Papers commonly used as end paper include offset paper, coated paper, card paper.&lt;br /&gt;
Offset paper is mostly white as end paper. Different grades of books use different quantification of end paper. For paperback book printing, the ration is 60-150g/square meter, and for higher-grade books and picture book printing, the ration is 200-250g/square meter. To avoid wrinkling when pasting, the thread direction of the end paper should be parallel to the spine of the book.&lt;br /&gt;
&lt;br /&gt;
Coated paper is used as a end paper for higher-grade books, and the ration is generally between 100 and 250g/square meter. Decorative patterns related to the content of the book can also be printed to increase the decorative effect of books.&lt;br /&gt;
&lt;br /&gt;
Card paper is used as a end paper for picture album and [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing], with unique charm.

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;

== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;br /&gt;
&lt;br /&gt;
== What does your hardcover book look like ==&lt;br /&gt;
&lt;br /&gt;
Why do readers expect to receive a printed hardcover book?&lt;br /&gt;
&lt;br /&gt;
Have you ever wondered what expectations customers will have when they are buying a hardcover book online? And nowadays, online shopping is widely carried out, but readers can't touch the book they are interested in if they buy a book online. So, how will they judge what the book they buy is most likely to look like?&lt;br /&gt;
&lt;br /&gt;

This time, let's briefly understand the knowledge related to the &amp;quot;book&amp;quot; itself.&lt;br /&gt;
&lt;br /&gt;
[[File:_DSC0493.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What is the difference between paperback book and hardcover book?&lt;br /&gt;
&lt;br /&gt;
For book printing in China, paperback book printing is basically used art paper in cover and perfect binding. The hardcover book printing is basically used board paper in cover and thread binding.&lt;br /&gt;
&lt;br /&gt;
The book printing design decides the hardcover book printing ways and their eventually appear; the bookbinding is an important part of the book printing design; the paperback and hardcover both are the bookbinding concept.&lt;br /&gt;
&lt;br /&gt;
According to the book printing company, paperback and hardcover can be identified by the book cover paper. Furthermore, the cover also can decide the binding ways for the book printing.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The structure of the hardcover book&lt;br /&gt;
&lt;br /&gt;
In addition to the cover of the book itself, no matter paperback or hardcover for book printing, the outer layer of the book is usually covered with a protective cover. The following is a hardcover book to introduce the structure of each part of the book.&lt;br /&gt;
&lt;br /&gt;
This is the basic structure of hardcover book, which can be found in [https://www.chinaprinting4u.com/Hardcover_Book_50.htm hardcover book printing]. The paperback book differs in the composition of the cover and the end paper.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;

&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;

  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;

== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;br /&gt;
&lt;br /&gt;
== Coated &amp;amp; Offset Paper:Which Is better For Printing ==&lt;br /&gt;
&lt;br /&gt;
Both offset paper and coated paper are often used in [https://www.chinaprinting4u.com/ '''China printing service''']. So when choosing paper for book printing, which is better? In fact, the choice of book paper should carefully consider paper characteristics, book positioning, paper thickness, weight, price, etc. Let's briefly talk about it!&lt;br /&gt;
&lt;br /&gt;
What is offset paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:offset paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Offset paper is generally divided into three grades: A, B, and C. Grade A and B offset paper are usually made of 100% bleached softwood pulp or combined with bamboo pulp, cotton pulp, and grass pulp. Grade C offset paper uses 50% bleached wood pulp, and can also be mixed with part of cotton pulp or bamboo pulp.&lt;br /&gt;
&lt;br /&gt;
Its flexibility is small, water resistance is strong, and the absorption of ink is uniform, so the ink with better quality should be selected. Offset paper is suitable for printing monochromatic or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
What is coated paper?&lt;br /&gt;
&lt;br /&gt;
 [[File:coated paper.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
Coated paper is generally high-grade printing paper, and its printing particles are extremely fine, so it has high smoothness and good gloss. It is mainly used for printing covers and illustrations of high-grade books (such as [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm '''custom hardcover book'''] covers), color pictures, various exquisite commercial advertisements, samples, commodity packaging, etc. &lt;br /&gt;
&lt;br /&gt;
The difference between coated paper and offset paper:&lt;br /&gt;
&lt;br /&gt;
The coated paper is coated on both sides, while the offset paper is not. Offset paper is similar to the base paper of coated paper, that is, uncoated coated paper.&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly single-sided offset printing paper. The surface of the paper is white and smooth, but the whiteness, tightness and smoothness are lower than those of coated paper. &lt;br /&gt;
&lt;br /&gt;
Check out below 4 parts to find out which one is better for printing&lt;br /&gt;
&lt;br /&gt;
1. Features of paper&lt;br /&gt;
&lt;br /&gt;
Offset paper is not easy to stretch or get wet with water, has a tight texture, smooth touch, slightly yellowed, opaque, mostly used for books with few pictures, black and white, full color, and two-color are applicable. &lt;br /&gt;
&lt;br /&gt;
The surface of the coated paper is smooth and reflective, with good elasticity, uniform fiber distribution, and consistent thickness. It is mostly used for full-color books with many pictures, such as photo book printing, color magazine and beauty book printing. &lt;br /&gt;
&lt;br /&gt;
2. Book’s positioning&lt;br /&gt;
&lt;br /&gt;
Which one is better, offset paper or coated paper, is mainly to choose according to the type of book, not &amp;quot;just choose the expensive&amp;quot;, but to choose the right one. &lt;br /&gt;
&lt;br /&gt;
If it is a book that contains a large number of pictures (such as photo book printing，catalogue printing, [https://www.chinaprinting4u.com/Cooking_Book_Printing_57.htm '''custom recipe book printing'''], etc), publishers usually choose coated paper with a smooth surface and high color rendering performance, rather than offset paper that may cause color difference due to ink de-powdering, hair pulling, and color cast. &lt;br /&gt;
&lt;br /&gt;
If it is a book with a large number of text displays and a small number of pictures (such as storybook printing), the publisher usually chooses offset paper with a yellowish color and a relatively lower price, which can achieve the purpose of reducing costs. The coated paper has a higher whiteness, and readers are prone to visual fatigue after reading for a long time, which affects the reading experience.&lt;br /&gt;
&lt;br /&gt;
3. Paper thickness and weight&lt;br /&gt;
&lt;br /&gt;
In addition to which one is better, offset paper or coated paper, the thickness and weight of the paper are also considerations for book paper. There are different origin classifications of paper, and the thickness and price of different varieties of paper are also different, but usually, the coated paper of the same gram is much thinner than the offset paper.&lt;br /&gt;
&lt;br /&gt;
4. The price of paper&lt;br /&gt;
&lt;br /&gt;
The cost of offset paper is generally low, and it is mostly used for pictorial, maps, etc., while coated paper, as a high-grade paper, is of course not cheap.&lt;br /&gt;
&lt;br /&gt;
In short,there is no better between coated paper and uncoated paper, only suitable or not.When you start printing books in China, you should consider which one is more suitable for your book based on 4 aspects of paper characteristics, price, thickness and weight, and positioning of the book.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;
== How to choose the paper for your printing project? ==&lt;br /&gt;
&lt;br /&gt;
In '''China printing service'''[https://www.chinaprinting4u.com/ china printing service],select the paper for your printing project is one of the most important parts,which will directly affect the final presentation and the cost of your printed products. &lt;br /&gt;
&lt;br /&gt;
Our commonly used printing paper can be divided into the following night Categories：White cardboard, gray board, coated paper, offset paper, corrugated paper, specialty paper, writing paper, Kraft paper, newsprint,etc. &lt;br /&gt;
&lt;br /&gt;
1. White cardboard:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;

While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;

 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;br /&gt;
&lt;br /&gt;
== What Kind Of Children's Book Attracts Children? ==&lt;br /&gt;
&lt;br /&gt;
Children’s psychology is simple and complex. What kind of printed children's book can fit children's minds, and produce valuable &amp;quot;first-sight effects&amp;quot;? Publishing and printing a children's book is a huge project. It requires the authors and [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children's book printing'''] designers to make great efforts in children's book concepts, colors, printed materials, etc., in order to print and publish a book that is loved by children.&lt;br /&gt;
&lt;br /&gt;
[[File:children book printing.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
What is the concept of children book?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When children's book authors and children's book printing designers understand the concept of the books, it is easy to finish the book based on children's psychology.&lt;br /&gt;
&lt;br /&gt;
1. When writing children's books, the writers should pay attention to the actual reading needs of children's readers and respect children's psychological characteristics.&lt;br /&gt;
&lt;br /&gt;
2. When designing a children's book, designers should design the printed children's books with a childlike heart, so that the books have artistic and market vitality.&lt;br /&gt;
&lt;br /&gt;
3. Regardless of whether it is the content or design of children's books, please throw away your rational shell when creating, and try to observe the world with children's eyes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Choose different colors as per the reader's age&lt;br /&gt;
&lt;br /&gt;
Color is an eye-catching artistic language in children's book printing. Children's book printing color has visual impact and is an important element to beautify children's book printing. Children's book printing is inseparable from bright colors and images, because rich colors can cultivate children's aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
1. Children like brightly colored images, so bold colors can be used in the printing design of children's books to attract children's attention. However, unscientific color usage may cause harm to children's eyes.&lt;br /&gt;
&lt;br /&gt;
2. Clarify the positioning of children's book printing colors, and match colors according to children's preferences.&lt;br /&gt;
&lt;br /&gt;
Children of all ages have different perceptions of color. Before [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''printing children's book'''], you need to know which age children are your readers.&lt;br /&gt;
&lt;br /&gt;
For example: children in early childhood can only recognize basic colors such as red, yellow, and blue; children over 3-5 years old can gradually distinguish the concentration and purity of colors; children over 6 years old are more able to distinguish colors and prefer colors with strong contrast.&lt;br /&gt;
&lt;br /&gt;
In short, color is an important bridge for information transmission between children and the book. Designers and authors use color to guide children to better perceive the outside world and cultivate their keen aesthetic ability.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Please make sure to use safe materials in children's book printing&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Unlike adults, children do not rely solely on vision to perceive the world, but touch is also a very important way. Therefore, the selection of children's book printing materials needs to ensure safety. When choosing children's book printing materials, children's book printing designers must not only consider the overall effect of the book, but also consider the age group of the readers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. Children between the ages of 3 and 6 cannot read text freely. Therefore, books of this age group are mostly based on graphics. When choosing paper, designers should choose paper with better color expression and thicker texture.&lt;br /&gt;
&lt;br /&gt;
2. The reading ability of children between the ages of 7 and 13 has been greatly enhanced, and children in this period have already gone to school, so when books of this age group should choose paper or other materials with natural colors and a small burden on the eyes.&lt;br /&gt;
&lt;br /&gt;
3. When printing children's books of younger ages, you should try to avoid choosing coated paper, because this kind of paper has high hardness and sharp edges, which can easily cause damage to the skin of children.&lt;br /&gt;
&lt;br /&gt;
4. When choosing fabrics for children's book binding and finishing ways, cotton fabrics should be used more, because it has a soft texture.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

== How to know the common sense of Chinese printing? ==&lt;br /&gt;
&lt;br /&gt;
  Prints often appear in our lives, but how much do you know about '''Chinese printing'''[https://www.chinaprinting4u.com/ chinese printing] knowledge?&lt;br /&gt;
&lt;br /&gt;
Whether it is promotional albums, books printing, '''catalogue printing'''[https://www.chinaprinting4u.com/ catalogue printing], brochure printing, or business cards, etc, they are all inseparable from printing. Today, we will help you quickly understand printing knowledge through the two parts of printing method classification and paper classification.&lt;br /&gt;
Part 1 : How to classify printing method?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Classification of printing methods, which can be divided into:&lt;br /&gt;
 (1) offset printing, that is, lithographic printing, which is printed on a flat surface, such as paper and self-adhesive;&lt;br /&gt;
(2) Embossed printing, also called flexo printing, is generally used in plastic printing;&lt;br /&gt;
(3) Screen printing, which is what we call universal printing, it can be printed on any object and is very flexible, but it has a disadvantage that it is not suitable for large-scale printing.&lt;br /&gt;
Part 2 : How to classify printing paper?&lt;br /&gt;
&lt;br /&gt;
Commonly used paper for China printing Paper can be divided into industrial paper, packaging paper, household paper, cultural paper, etc. according to different uses, among which cultural paper includes writing paper, art drawing paper, printing paper, etc. .&lt;br /&gt;

== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;
&lt;br /&gt;
If you don’t have any idea to choose the paper for your own children’s book printing.Please contact us soon,we have more than 20 years of children’s book printing experience,we will give you the best suggestion to print your own children’s book&lt;br /&gt;

== Why coffee table books can resist digitization? ==&lt;br /&gt;
&lt;br /&gt;
While many magazines and book publishing have transformed from book printing to digital publishing, the [https://www.chinaprinting4u.com/Book_Printing_32.htm '''coffee table book printing'''''Text kurzívou''] market is still dominated by paper book printing.&lt;br /&gt;
[[File:coffee table book printing china.jpg|400px]]&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Now is the era of digitization. As early as a few years ago, many self-published writers and magazine publishers abandoned printed book publishing, and gradually transformed to digital and issued their e-books. This makes us have to think, is there no other way for book printing except change to e-books? No, in any case, there is at least one type of printed book that e-books and digitized reading cannot replace, and that is the books that accompany you on the coffee table.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
What are the coffee table books?&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
“A really well-made coffee table book is like a piece of art. Through the use of color and color repetition and other details, it can be coordinated with and integrated into the whole room, and it makes the room very different.” – Ellen Fisher in “Marketing Operations.”&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
The beginning of the printed coffee table book&lt;br /&gt;
&lt;br /&gt;
In the 1950s, Paul Steiner, the founder of Chanticleer Press, created the earliest printed coffee table book “the photography guide series? This was the first time that coffee table book printing appeared in the publishing industry. At that time, the printed coffee table books with nature as the theme were prevalent, so Chanticleer Press successively published other series: “Taylor’s Guides to Gardening? and “The Stones of Florence”.&lt;br /&gt;
&lt;br /&gt;
In the 1960s, David Brower, president of Sierra Club, proposed the idea of “modern coffee table books”, hoping that the printed coffee book could be presented to readers in a way similar to a photography exhibition.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
== What paper is best for printing children books? ==&lt;br /&gt;
&lt;br /&gt;
[https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''Children book printing'''] generally use letterpress and offset paper. &lt;br /&gt;
&lt;br /&gt;
 [[File:DSC_0747.JPG|400px]]&lt;br /&gt;
&lt;br /&gt;
Letterpress paper is used for printing children’s books with more text, such as fairy tales, fables,children's essays or novels. The fiber structure of letterpress paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and sizing materials,also bleached, which makes this paper suitable for children's story book printing.&lt;br /&gt;
&lt;br /&gt;
At the same time, letterpress paper has the characteristics of uniform texture, no lint, slightly elastic, opaque, slightly water-resistant, and has certain mechanical strength. The advantage of letterpress paper is low-cost and easy to read, but this kind of paper is easy to smear, and it lacks brightness. When printing pictures, it cannot express the effect of pictures well, so it is not suitable to print children picture book .&lt;br /&gt;
&lt;br /&gt;
Offset paper is mainly used for higher-grade [https://www.chinaprinting4u.com/ '''coloring book printing'''], such as printing monochromatic or multi-color book covers, text, poke pages, pictorials, maps, posters, color trademarks and various packaging products.&lt;br /&gt;
&lt;br /&gt;
Offset paper has low shrinkage, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance. Therefore, offset paper for children picture book printing is more suitable. But its disadvantage is that if print the text, it will reflect light, which is not suitable for long-term reading.&lt;br /&gt;
&lt;br /&gt;
The paper requirements of children’s book printing have different requirements for different contents, which have been discussed above. I think the paper requirements are different for different age of children.&lt;br /&gt;
&lt;br /&gt;
For young children,who are just beginning to read, the books they read are almost picture books, therefore, [https://www.chinaprinting4u.com/Children_Book_Printing_51.htm '''children picture book printing'''] use offset paper is more suitable.In addition, young children do not have the awareness of caring for books. Thin letterpress paper is prone to wrinkles and holes, while good quality offset paper has high hardness and is not easy to tear, making it more suitable for young children's picture books.&lt;br /&gt;
&lt;br /&gt;
For older children,who had been know how to read the book,and they prefer story books.Therefore,children’s story book printing use letterpress paper is more suitable.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;
== How to choose the paper for your printing project? ==&lt;br /&gt;

== How to know the common sense of Chinese printing? ==&lt;br /&gt;
&lt;br /&gt;
  Prints often appear in our lives, but how much do you know about '''Chinese printing'''[https://www.chinaprinting4u.com/ chinese printing] knowledge?&lt;br /&gt;
&lt;br /&gt;
Whether it is promotional albums, books printing, '''catalogue printing'''[https://www.chinaprinting4u.com/ catalogue printing], brochure printing, or business cards, etc, they are all inseparable from printing. Today, we will help you quickly understand printing knowledge through the two parts of printing method classification and paper classification.&lt;br /&gt;
Part 1 : How to classify printing method?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Classification of printing methods, which can be divided into:&lt;br /&gt;
 (1) offset printing, that is, lithographic printing, which is printed on a flat surface, such as paper and self-adhesive;&lt;br /&gt;
(2) Embossed printing, also called flexo printing, is generally used in plastic printing;&lt;br /&gt;
(3) Screen printing, which is what we call universal printing, it can be printed on any object and is very flexible, but it has a disadvantage that it is not suitable for large-scale printing.&lt;br /&gt;
Part 2 : How to classify printing paper?&lt;br /&gt;
&lt;br /&gt;
Commonly used paper for China printing Paper can be divided into industrial paper, packaging paper, household paper, cultural paper, etc. according to different uses, among which cultural paper includes writing paper, art drawing paper, printing paper, etc. .&lt;br /&gt;
In the printing paper, according to the performance and characteristics of the paper, it is divided into newsprint, letterpress printing paper, offset printing coated paper, dictionary paper, map and marine drawings, gravure printing paper, painting newspaper, weekly newspaper, whiteboard paper, writing paper, etc. . In addition, some high-end prints also widely use art drawing paper.&lt;br /&gt;
coated paper&lt;br /&gt;
(1) Features: smooth surface, high whiteness, uniform distribution of paper fibers, consistent thickness, small stretchability, good elasticity, strong water resistance and tensile properties, and absorption and acceptance of ink Condition is very good. There are two types of coated paper: single-sided and double-sided.&lt;br /&gt;
(2) Main use: mainly used for printing albums, covers, postcards, exquisite product samples and color trademarks.&lt;br /&gt;
sublime paper&lt;br /&gt;
(1) Characteristics: The difference from the coated paper is that the surface of the paper is matte, the paper fibers are evenly distributed, the thickness is good, the density is high, the elasticity is good, and it has strong water resistance and tensile properties. The absorbency and receiving state are slightly lower than that of coated paper, but the thickness is slightly higher than that of coated paper.&lt;br /&gt;
(2) Main use: mainly used for printing albums, cards, postcards, exquisite product samples, etc.&lt;br /&gt;
  White cardboard paper&lt;br /&gt;
(1) Features: It is a thick and firm white cardboard. There are two types of yellow core and white core.&lt;br /&gt;

== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;br /&gt;
&lt;br /&gt;
== What Cause Board Book Warping And Deforming? ==&lt;br /&gt;
&lt;br /&gt;
Board book warping and deforming is a common technical problem encountered by [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printers''']. &lt;br /&gt;
&lt;br /&gt;
Board books include hardcover books with gray boards as bookcases and books mounted with cardboard with a weight of 200-250 grams per square meter. They are very common in book printing companies and are prone to quality problems such as warping and deforming.&lt;br /&gt;
&lt;br /&gt;
What cause board book warping and deforming?&lt;br /&gt;
&lt;br /&gt;
1. Raw materials&lt;br /&gt;
&lt;br /&gt;
The structure of the gray board or cardboard itself determines that it is easier to warp and deform during board book printing. Gray board or cardboard has high density and long fibers, and its water absorption has a great influence on the structure of board books.&lt;br /&gt;
&lt;br /&gt;
When absorbing water, the fibers of the gray board or cardboard will stretch, due to gray board or cardboard has a certain thickness, the amount of water absorbed on both sides will be inconsistent, resulting in different elongation lengths of the fibers of the gray board or cardboard, which makes gray board or cardboard deforming.&lt;br /&gt;
&lt;br /&gt;
 At the same time, when water is lost, the fibers of the gray board or cardboard will shrink, but the inconsistent water loss on both sides will cause the fibers to shrink inconsistently, resulting in deformation.&lt;br /&gt;
&lt;br /&gt;
Although the gray board or cardboard will deform due to water absorption and water loss, the deformation caused by water loss is more serious than water absorption. In addition, different brands and types of gray board or cardboard have different water absorption and deformation extent in custom [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''board book printing'''].&lt;br /&gt;
&lt;br /&gt;
2. Ambient temperature and humidity&lt;br /&gt;
&lt;br /&gt;
The environmental temperature and humidity have a great influence on the printing board books. When the ambient temperature and humidity are lower than the water content of the cardboard, it will cause the cardboard to lose water, and the degree of water loss in each part of the cardboard is generally different, resulting in warping and deformation of the cardboard.&lt;br /&gt;
&lt;br /&gt;
When the ambient temperature and humidity are higher than the water content of the cardboard, it will cause the cardboard to absorb water, which will also cause the cardboard to warp and deform.&lt;br /&gt;
&lt;br /&gt;
The degree of deformation in these two cases are different. The deformation when water is lost is much greater than that when water is absorbed, so the warping deformation of board books always occurs in the dry seasons of autumn and winter.&lt;br /&gt;
&lt;br /&gt;
3. Production process&lt;br /&gt;
&lt;br /&gt;
When print a board book, it is necessary to cover or mount with white latex. The white latex contains a lot of water. When the shell is placed or mounted, a large amount of water will enter in the cardboard, but the water does not enter uniformly, which leads to inconsistent moisture content in each part of the cardboard, finally leads to the board books warping and deforming.&lt;br /&gt;
&lt;br /&gt;
4. Production method&lt;br /&gt;
&lt;br /&gt;
When [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm '''custom board book'''], some companies use machines to automatically load them, and some companies are artificial shell. Automatic shelling by machines is generally more uniform than the adhesive applied by artificial shell, so that the moisture content of the cardboard is more uniform.&lt;br /&gt;
&lt;br /&gt;
At the same time, the viscosity of the adhesive used for automatic shelling by machine is different from that of the adhesive used for manual shelling, that is, the solid content of the adhesive is different. The solid content of the adhesive should be high, and the water content should be small, and it is less likely to cause  board book warping and deforming.&lt;br /&gt;
&lt;br /&gt;
5. Process design&lt;br /&gt;
&lt;br /&gt;
Whether it is gray board or cardboard, all have textures, so when the board book is shelled or mounted, it needs to be carried out according to the texture. A lot of production experience tells us that for [https://www.chinaprinting4u.com/Board_Book_Printing_65.htm custom board books]'''custom board books''', it is necessary to cover the casing along the grain; for the mounted book, it needs to be mounted along the grain. If it does not follow the grain, the finished cardboard book will have serious warping deformation in the later stage.&lt;br /&gt;
&lt;br /&gt;
In short,raw materials,ambient temperature and humidity, production process, production method ,process design,these five aspects,which are the mainly factors to cause the board book warping and deforming.In next article,we will focus on how to solve board book warping and deforming.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;
&lt;br /&gt;
== How to choose the paper for your printing project? ==&lt;br /&gt;
&lt;br /&gt;
In '''China printing service'''[https://www.chinaprinting4u.com/ china printing service],select the paper for your printing project is one of the most important parts,which will directly affect the final presentation and the cost of your printed products. &lt;br /&gt;
&lt;br /&gt;
Our commonly used printing paper can be divided into the following night Categories：White cardboard, gray board, coated paper, offset paper, corrugated paper, specialty paper, writing paper, Kraft paper, newsprint,etc. &lt;br /&gt;
&lt;br /&gt;
1. White cardboard:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
It is a kind of thick, thick and heavy paper. The surface of this paper is smooth and calendered with high stiffness. &lt;br /&gt;
&lt;br /&gt;
Characteristics: Single-layer or multi-layer combined paper made entirely by bleached chemical pulping and fully sizing, generally the basis weight is above 150g/�? The characteristics of this cardboard are: high smoothness, good stiffness, neat appearance and good formation. &lt;br /&gt;
&lt;br /&gt;
Common weights: white cardboard weights of 200, 250, 300, 350, 400 grams are more commonly used. &lt;br /&gt;
&lt;br /&gt;
Advantages: thick enough and hard enough. The hardness of the cardboard is very high among the paper of the same number of grams. People who like thick cards will really appreciate this paper. The color is not less than coated paper, also very colorful. Writing on the reverse side is easily wiped off immediately. This paper with cost-effective, the price is in the middle. &lt;br /&gt;
&lt;br /&gt;
Disadvantages: It is easy to scratch, from printing to writing, daily touch is very easy to scratch the front very ugly, generally high-grade cardboard will be covered with film to prevent scratches. In particular, black and dark colors will have traces when touched lightly. And irreversible. &lt;br /&gt;
&lt;br /&gt;
Usage:Printing business cards, certificates, invitations, packaging boxes, tags, handbags, covers, monthly desk calendars and postal postcards, etc.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;br /&gt;
&lt;br /&gt;
== Common cardboards for hardcover book printing ==&lt;br /&gt;
&lt;br /&gt;
There are many materials involved in [https://www.chinaprinting4u.com/Hardcover_Book_Printing_50.htm hardcover book printing]. Selecting the appropriate material for the cover processing can not only ensure the smooth progress of the book cover processing process, but also avoid the occurrence of quality problems such as book cover warping. Cardboard is used as the bones of the bookcase, and its thickness, tightness, flatness, moisture content, strength, etc. are closely related to the book processing effect. Knowing the type of cardboard and choosing the cardboard suitable for different processing needs is very important for making high-quality products.&lt;br /&gt;
There are three kinds of cardboards commonly used in binding in [https://www.chinaprinting4u.com Chinese printing houses], white cardboard with gray background, straw cardboard and yellow cardboard.&lt;br /&gt;
&lt;br /&gt;
1. White cardboard paper with grey background&lt;br /&gt;
Grey-bottomed whiteboard paper is made of ground wood pulp, semi-chemical wood pulp, straw pulp and the same waste paper pulp in a multi-layer (usually 3-layer) structure. The grey-ground whiteboard paper has a smooth surface (calendered) and is suitable for making all kinds of bookcases.&lt;br /&gt;
The following points should be paid attention to when using whiteboard paper with gray background.&lt;br /&gt;
(1) Choose the appropriate cardboard according to the grade of the processed product, and choose the appropriate thickness according to the thickness and size of the booklet.&lt;br /&gt;
(2) According to the experience of [https://www.chinaprinting4u.com Chinese printers] for many years, when the moisture content of the cardboard purchased in winter is too large, do not rush to use it, but store it for a period of time to allow the moisture to naturally volatilize and balance with the ambient humidity before use. Do not dry the material after opening, as this will reduce the size of the bookcase and make it impossible to fit the book block.&lt;br /&gt;
(3) When processing with an automatic hot stamping machine, if the thickness tolerance of the cardboard is found to be large, it should be checked and selected in advance, and roughly divided according to the thickness, or a manual hot stamping machine can also be used for processing.&lt;br /&gt;
(4) When it is found that the cardboard is separated from the layer during cutting, it is neither suitable for cutting into small format nor for medium-diameter cardboard, because the cardboard paste that is not strong between the layers will cause uneven appearance, bulging and warping after the book case is made of paste. The phenomenon such as melody affects the appearance quality of the book.&lt;br /&gt;
&lt;br /&gt;
2. Straw cardboard&lt;br /&gt;
Its surface is rough and yellow, and the main raw material is straw fiber. The thickness of straw board is generally 0.7mm, and the thickness can be increased after lamination. This kind of cardboard has low tightness, high elongation, poor toughness, and strong surface moisture absorption and penetration ability.&lt;br /&gt;
The following points should be paid attention to when using straw cardboard as a book cover.&lt;br /&gt;
(1) Do not rush to use the straw cardboard after purchasing it, and store it for a period of time to make it flat and obedient.&lt;br /&gt;
(2) When encountering damp cardboard, it should be stored for a period of time to allow it to dry naturally to a certain extent before use. If conditions permit, it can be heated with a cardboard press (the heating temperature is generally around 65°C) and pressurized before use, so that the rough surface of the cardboard is flat, the tightness is increased, and the humidity is appropriate (preserve reasonable internal moisture).&lt;br /&gt;
(3) When pasting the book case, use an adhesive with less moisture, fast drying and good viscosity, and improve the lining process, so that the tension on the inside of the cover (the second and third) is greater than that of the outside, so as to avoid post-printing processing. The bookcase warps outwards.&lt;br /&gt;
(4) When making bookcases with a size of 16K or above, a single lining should be mounted on the inside of the cover to balance the tension between the inside and outside of the cover.&lt;br /&gt;
&lt;br /&gt;
3. Yellow cardboard&lt;br /&gt;
Yellow cardboard is a kind of smoky brown (the same color as kraft paper), smooth surface, hard texture and high toughness. It is mainly used for making outer envelopes and some bookcases in bookbinding. The outer cover of the book made of yellow cardboard has good durability and is not easy to wear, which can effectively protect the book and improve the grade of the book. Because of its high tightness and small thickness error, it is also beneficial to control the hot stamping pressure. The following points should be noted when making shells and envelopes.&lt;br /&gt;
(1) The yellow cardboard is hard and tough, and it is difficult to correct the warpage and deformation. Therefore, after the case is made, a press or stacking method should be applied to give a certain pressure to prevent the warpage and deformation of the bookcase.&lt;br /&gt;
(2) The hardness of yellow cardboard is high, suitable for hot stamping embossing marks, and it is firm and durable without deformation, but the hot stamping pressure is larger than other cardboards.&lt;br /&gt;
(3) When processing the finished lining, be sure to make the inner pull force greater than the outer pull force to prevent the outer pull force from being too large to prevent the book case from warping upward and being difficult to level.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;

&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

== How to choose right Chinese printers? ==&lt;br /&gt;
&lt;br /&gt;
Book printing is something that we must focus on in the business process, so how to choose '''right book printing companies'''https://www.chinaprinting4u.com when printing our product? Now let's take a look.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
1.You need to know your printing requirement.&lt;br /&gt;
&lt;br /&gt;
   No printer in the world can print all types of product.Among all kinds of printing enterprises, the enterprises engaged in printing publications (books, periodicals, newspapers, etc.) account for about the total number of printing enterprises 10% of the total, and about 30% of the enterprises are engaged in packaging and decoration printing materials (trademark logo, advertising, packaging paper, metal, plastic, etc).&lt;br /&gt;
The rest are engaged in printing other printed materials (documents, materials, charts, tickets, etc.). According to the above data,although the printing companies are many, but the products who can provide are different. Therefore, before looking for a printing company, you must be clear about your printing requirement, so that we can correctly find the right printing company. Such as if you need a moon cake box, of course, you have to find a color box printing supplier.Printing company can print what products are actually depend on their production equipment. For example, if a newspaper printing factory needs a professional newspaper rotary printing machine;In addition to ordinary printing machines,[https://www.chinaprinting4u.com/ custom book printing] plants also need folding machines, bookbinding (glue binding, horse riding binding, thread binding, etc) equipment and paste mounting equipment; In addition to the printing machine, we also need other post printing processing equipment, such as die-cutting machine (beer machine), bronzing (silver, laser) equipment, laminating machine, UV machine, gluing machine, etc.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
2.You need to clear the quality requirements for products&lt;br /&gt;
&lt;br /&gt;
This is also very important. Different quality requirements can determine what kind of suppliers to find. Generally speaking, large-scale company’s product quality will be more guaranteed. Because both the progressiveness of equipment and quality of employees are relatively high. Product quality can be effectively guaranteed also depends on the improvement of management system and complete processing equipment of large-scale manufacturer. It is the latter two points to ensure the long-term stability of product quality. Actually, a large number of manufacturers are small in scale, but their equipment is advanced.The quality of employees is as good as most of large factories. What they lack is perfect management and product processing equipment, which leads to product quality and quantity fluctuates greatly. Therefore, when the product requirements are high, it is necessary to choose large and medium-sized printing factories.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
3. You need to know how many to print&lt;br /&gt;
&lt;br /&gt;
The quantity directly affects the selection of printing companies. Such as,if you need to print children’s book for 500 copies, you can choose small and medium-sized printing plants. Because in terms of quantity, we should printing 500 copies of such book is not a problem for most printing company. Both the quality and quantity are very good guarantee. However, if the number rises to 5000 or 10000 copies, we should choose medium-sized or large-scale printing company, because only the large-scale companies have enough production capacity to complete the task according to quality within a certain time. (small printing houses refer to below 100 people, medium-sized refers to more than 100 people but less than 500 people, and large refers to more than 500 people. Note: this classification standard is for reference only)&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
4. Select printing suppliers according to price affordability.&lt;br /&gt;
  As the saying goes, &amp;quot;you get what you pay for&amp;quot; .If the price affordability is not high, you can only find a non famous brand printing manufacturer.There is a big difference in price between famous brands and non famous brands, because brands are intangible values and have a good reputation in quality.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The above are the precautions for us to find right book printing company to custom printing service for your product, I hope it can help you.&lt;/div&gt;</summary>

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;br /&gt;

&lt;div&gt;                                                 '''3 Eco-friendly Ink For Children’s Book Printing'''&lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
  Recent years,more and more parents like to purchase Eco-friendly children books for their children, which makes children's book printers''''''Tučný text'''https://www.chinaprinting4u.com/''' reduce to use ink or use Eco-friendly inks when print children’s book.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
  In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  2. Volatile substances, solvents and additives used in ink, include aromatic hydrocarbon, alcohol, etc. They evaporate as the ink dries and enter the reader's respiratory system.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
  What types of environmentally friendly inks are included?'''&lt;br /&gt;
&lt;br /&gt;
  1. Rice bran ink&lt;br /&gt;
&lt;br /&gt;
  Rice bran ink technology originated from Japan. At present, many institutions and '''book printing companies in china'''https://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. &lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Without exerting its maximum value, the development of rice bran oil refining technology and the technological breakthrough of rice bran oil in ink not only maximizes the value of rice bran, but also further improves the environmental protection and sustainable development of printing ink.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  The main advantages of rice bran ink are: ink VOC (Volatile Organic Compounds, volatile organic compounds) residue is low, migration is low, and environmental pollution is little; rice bran resources are easy to localize, which is in line with Chinese national conditions; The residue of harmful substances is small and the safety is high.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  However, the development of rice bran ink is also affected by some objective conditions and ink performance defects, mainly including: China's rice bran oil refining and utilization technology is not developed and popularized enough, the scale is not enough, the cost of rice bran oil is relatively high; The drying speed is slow; the application technology of rice bran ink is not popular enough, and the printing operation and control details are not well known, etc.So rice bran ink is not widely used in children's book printing China.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  ''''''Tučný text''''''2.Soybean ink&lt;br /&gt;
&lt;br /&gt;
  The aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, but the influence of VOC is still unavoidable. Therefore, some of the mineral oil is replaced by soybean oil in soybean ink. After mildly purifying soybean oil, it is mixed with additives such as pigments and resins.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 Soybean inkink has many advantages: scratch resistance, no irritating odor, light and heat resistance, easier to recycle, wide color, etc. In addition to soybean oil, other vegetable oils can also be used, such as linseed oil.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Now,many printing companies often use the soybean ink to '''printing children’s books.'''https://www.chinaprinting4u.com/&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
'''&lt;br /&gt;
3.Water-based ink&lt;br /&gt;
'''&lt;br /&gt;
  Water-based ink does not contain volatile organic solvents, and only needs to be diluted with water during printing. Therefore, the water-based ink greatly reduces the emission of VOCs and avoids the pollution of volatile organic compounds. At the same time, it significantly reduces the residual hazardous substances on the surface of printed products, and is one of the most environmentally friendly ink types.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
 In addition, the application of water-based ink can also reduce the fire hazard caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of the printed matter.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
  Therefore, the application of water-based inks in food packaging, children's board book printing, tobacco and alcohol packaging is becoming more and more common.&lt;br /&gt;
&lt;br /&gt;
== What to Consider When Choose Book Printing Paper ==&lt;br /&gt;
&lt;br /&gt;
  '''Book printing in china'''https://www.chinaprinting4u.com/, we always say choosing paper for a book is like finding a partner.Choose the paper for a book determines whether it matches the qualities of the book; in short, whether it can best present the content. &lt;br /&gt;
&lt;br /&gt;
When we choose the paper,we really need to consider is:how to choose the paper with cost-effective,good printing effect,best fits the book’s content and cheap.&lt;br /&gt;
&lt;br /&gt;
[[File:book printing china.jpg|400px]]&lt;br /&gt;
&lt;br /&gt;
 '''What are the parts include in choosing paper?'''&lt;br /&gt;
&lt;br /&gt;
 If for the paperback,which includes:&lt;br /&gt;
&lt;br /&gt;
  1. The inner paper;&lt;br /&gt;
&lt;br /&gt;
  2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)&lt;br /&gt;
&lt;br /&gt;
  3. Inner cover paper:not every book has it.&lt;br /&gt;
&lt;br /&gt;
  4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.&lt;br /&gt;
&lt;br /&gt;
  If for the hardcover book printing service,the paper includes:&lt;br /&gt;
&lt;br /&gt;
  1.Inner paper&lt;br /&gt;
&lt;br /&gt;
  2.The end paper&lt;br /&gt;
&lt;br /&gt;
  3.Mounting paper: It is the layer of paper or cloth mounted on the outside of the hard shell (remind everyone to consider the effect of the mounting paper after mounting).&lt;br /&gt;
&lt;br /&gt;
  4.Outer cover paper:not every book has it&lt;br /&gt;
&lt;br /&gt;
  5.Girdle paper: not every book has it.&lt;br /&gt;
&lt;br /&gt;
  '''When we choose the printing paper,what are we need to consider?'''&lt;br /&gt;
&lt;br /&gt;
  1.The printing effect.Your book is plain text or with many photos?If your book has many photos,what’s type of the photo.Do you need to see the details clearly, or is there only a general presentation? Is the blur of large particles more effective? Do you pay special attention to the restoration of color, or do you have no special requirements for color.&lt;br /&gt;
&lt;br /&gt;
  2.The gram weight of paper.Paper is generally priced by ton, that is to say, when the price for per ton is the same, you can buy more paper with low gram weight (generally thinner), so it is relatively cheaper, but the gram weight is relatively low. If it is too low, when the paper is printed on the machine, it is easy to wrinkle, and the printing ink, especially double-sided printing, is easy to penetrate, and the effect is very poor.&lt;br /&gt;
&lt;br /&gt;
  As for the high gram weight, the paper is relatively thick (the same kind of paper, regardless of the bulk), and it is thicker in the hand. It is often seen that we '''custom hardcover book''' https://www.chinaprinting4u.com/with relatively little content. If the price is relatively high, everyone thinks it is not worth it, but the weight increases. With the same number of pages, the whole book is much thicker, and the price also goes up.&lt;br /&gt;
&lt;br /&gt;
  Special reminder: There are some coated papers, their coating is deep into the paper texture (not only on the surface), this type of paper, the gram weight is more higher, coating is more thicker and the color reproduction is more better ; if the gram weight is lower, it will reduce the coating ability to restore color.&lt;br /&gt;
  &lt;br /&gt;
  3.The bulk of paper: imagine the paper as a cake. If paper with low bulk is like pancakes, thinner, and paper with high bulk is like a dough cake. So the same gram weight, the book is thicker.&lt;br /&gt;
&lt;br /&gt;
  4.The price of paper.Paper is one of the major costs in china book printing, especially today when the price of paper is rising.&lt;br /&gt;
&lt;br /&gt;
  5.Whether to close or open: the paper used for '''printing books in china'''https://www.chinaprinting4u.com/ has a certain size, and the commonly used sizes are different for different papers. During the process of cutting and folding the printing paper into the size of the book, if the size is not correct, it will waste the paper. Such as, before we custom spiral bound book printing, we must fully communicate with the book printing companies in china ,to ask whether this size and the use of this kind of paper will cause waste.&lt;/div&gt;</summary>

&lt;div&gt;  The '''children's book printing'''https://www.chinaprinting4u.com/ industry is becoming more and more prosperous as parents pay more and more attention to reading and more and more parents pay attention to reading. Every time the online store is promoted, the sales data of children's books are always quite amazing. At the same time, parents' requirements for printing children's books are also increasing simultaneously with the requirements for content, especially the safety and environmental protection of children's book printing. However,how much do you know about environmental protection of printed children's books?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  Environmental protection of print children's book is a daily problem that every parent who cares about children has to face.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  Nowadays, many parents pay attention to the cultivation of children's reading habits, so they prepare a variety of cards, picture books,board books and other printed materials for their children. However, if you don't pay attention to or care about the quality of printed materials when you buy a children’s book or '''print your own children’s board book'''https://www.chinaprinting4u.com/ for your children, it may cause some printed materials to have different degrees of negative impact on children's health.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
'''1. What kind of print will have a negative impact?'''&lt;br /&gt;
&lt;br /&gt;
  The quality and the environmental protection of children book printing cannot be confused.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The quality of the print is:&lt;br /&gt;
&lt;br /&gt;
(1) Handwriting&lt;br /&gt;
&lt;br /&gt;
(2) Clear lines&lt;br /&gt;
&lt;br /&gt;
(3) accurate color reproduction&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  The environmental protection of print a children’s book is: when children read the books, it does not bring health hazards to the children.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  Children book printing are specifically mentioned because when children read the book, harmful substances in printed materials are more likely to be ingested into the body.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  First: because children, especially young ones, may have the habit of tearing and biting books when reading;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  Second: Many children's reading materials have a large number of color pictures, and the amount of ink used is much more than ordinary text-based books. So printing children's books should have higher standards than ordinary books in terms of environmental protection.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  It is analyzed from the main materials of '''printing children's books in china'''https://www.chinaprinting4u.com/, such as paper, ink, glue and lamination:&lt;br /&gt;
&lt;br /&gt;
  (1)The ink may contain benzene, especially the color ink, which uses a solvent such as benzene. After the new book is printed, the solvent is not completely evaporated, and the reader will emit an unpleasant odor after opening the package.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
  Benzene and toluene are liquids with a strong odor and are highly toxic. They not only damage the respiratory tract, but also cause acute poisoning and paralysis of the central nervous system. Short-term inhalation can cause dizziness and nausea. Long-term exposure may damage the bone marrow and cause leukocyte and thrombocytopenia and aplastic anemia.&lt;br /&gt;
