                                                3 Eco-friendly Ink For Children’s Book Printing
 

 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.

 In this article,we will mainly introduce 3 types of eco-friendly ink for children book printing.

 To see whether the ink is an environmentally friendly ink, the following two points are mainly considered:

 1. Heavy metals, due to children's reading habits, heavy metals in ink may be inhaled from the mouth.

 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.

 What types of environmentally friendly inks are included?

 1. Rice bran ink

 Rice bran ink technology originated from Japan. At present, many institutions and book printing companies in chinahttps://www.chinaprinting4u.com/ are studying it. The main reason is that both China and Japan are big countries in rice consumption and production. 

 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.

 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.

 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.

 'Tučný text'2.Soybean ink

 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.

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.

 Now,many printing companies often use the soybean ink to printing children’s books.https://www.chinaprinting4u.com/

3.Water-based ink

 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.

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.

 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.

What to Consider When Choose Book Printing Paper

 Book printing in chinahttps://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. 

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.

What are the parts include in choosing paper?

If for the paperback,which includes:

 1. The inner paper;

 2. The end paper.It is the layer of paper between the cover and the text. (Some paperbacks don't use end paper)

 3. Inner cover paper:not every book has it.

 4. Girdle paper: not every book has it, and there are some books, the girdle is part of the outer cover.

 If for the hardcover book printing service,the paper includes:

 1.Inner paper

 2.The end paper

 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).

 4.Outer cover paper:not every book has it

 5.Girdle paper: not every book has it.

 When we choose the printing paper,what are we need to consider?

 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.

 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.

 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.

 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.
 
 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.

 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.

 5.Whether to close or open: the paper used for printing books in chinahttps://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.
