Color box packaging printing generally requires some special processing, such as light glue, matt glue, varnish, etc., based on the following factors:
Protect the color of printed matter, and the face paper printed in color box packaging is printed by ink. Under the action of ultraviolet light, it is easy to cause the printed matter to fade;
Waterproof, because the color box packaging is a paper product, in order to prevent the water from roting;
Anti-scratch, because the goods may be scratched on the way of transportation or movement, the color or material of the color box will be destroyed.
In this way, the brightness of the product can be improved, and the special surface treatment makes the product soft and soft rough face. More attractive to consumers.
