In terms of paper, light-weight paper has become a new choice for children’s book printing due to its light weight and low price. Coated paper is coated with chemical coatings on ordinary paper, but light paper is basically made of wood pulp, so it is more environmentally friendly. Although the colors printed on light paper may be darker than those printed on coated paper, it has a comfortable hand feel and light weight, making it more suitable for children to read. In addition, the price of light paper is lower than coated paper and double offset paper, so the price of books will be correspondingly cheaper.
In terms of inks, traditional mineral inks produce VOC volatile substances when manufacturing printed matter. A large amount of organic components volatilize during the ink manufacturing, printing, drying process or during equipment cleaning and waste ink treatment, which not only seriously endangers the health of production operators, but also The environment caused great damage. Books printed with traditional mineral oil and other chemical crude oils have a strong peculiar smell, are not environmentally friendly, and are easy to decolor.
Therefore, many books currently use soy ink to print, because soy ink is a new type of green and environmentally friendly ink, which is refined with 100% pure natural vegetable soybean oil, which is completely taken from nature, has no irritating odor, and is resistant to rubbing. No black hands, safe and non-toxic, rich in color, environmentally friendly and renewable. The most important point is that even if the baby bites or eats books with his mouth, it will not have any effect on the body.
