The children's book printing 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?

Environmental protection of print children's book is a daily problem that every parent who cares about children has to face.

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 for your children, it may cause some printed materials to have different degrees of negative impact on children's health.

1. What kind of print will have a negative impact?

The quality and the environmental protection of children book printing cannot be confused.

The quality of the print is:

(1) Handwriting

(2) Clear lines

(3) accurate color reproduction

The environmental protection of print a children’s book is: when children read the books, it does not bring health hazards to the children.

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.

First: because children, especially young ones, may have the habit of tearing and biting books when reading;

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.

It is analyzed from the main materials of printing children's books in china, such as paper, ink, glue and lamination:

(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.

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.

(2)Another source of irritating odors is the binding glue. Most of books binding glue uses quick-drying agent. This volatile chemical generally takes 10 to 20 days to completely disappear. However, the book is sealed in the packaging box and the smell cannot be emitted, so the reader will still have an odor after getting it.

(3)In addition, some inferior papers and adhesives contain a large amount of formaldehyde and emit a strong odor. Long-term exposure to such chemicals is very harmful to health and seriously affects children’s physical development.Because children’s reading habits are different from adults', poor-quality ink and paper may contain heavy metals, such as lead, which will enter the human body through the child's hand and mouth contact and affect the child's body.

(4)The lamination process of child book printing may also be harmful to children's health.

Lamination is a finishing process for surface decoration of printed products, which is widely used in book printing and packaging industries. However, many coating processes still use coating technology, which brings great harm to our environment and body. A large number of solvents containing benzene are used in the film coating process, and benzene is a strong carcinogen. Therefore, there are a large number of printing and packaging products covered by instant coating technology in our lives, such as the covered covers of textbooks and other books. The harm, especially to children, is very great.

According to a research report by the National Cancer Society of the United States, children who are exposed to benzene-containing products for a long time are most likely to suffer from blood diseases such as leukemia. Therefore, custom children's book printing should not use the lamination process as much as possible.
