Generally speaking, the printing of Yifan printing color box packaging needs some special processes, such as bright glue, matte glue, varnish and so on. , generally based on the following factors: 1. Protect the color of printed matter, the paper printed in color box packaging is printed with ink, which is easy to cause the printed matter to fade under the action of ultraviolet rays; 2. Waterproof function, because the color box packaging is a paper product, in order to prevent it from rotting in water; Improve the brightness of the product, and after special surface treatment, the product feels soft and rough. More attractive color box packaging surface treatment process: the advantages of film covering are waterproof, storage-resistant and beautiful. Film-covering adhesive refers to a kind of adhesive that combines bopp film on paper. At present, there are two ways to contact printing and packaging in China, one is water-based laminating, and the other is oily laminating. The current water-based film mulching method is mainly based on the concept of environmental protection, and the effect is slightly worse than that of oily film mulching. There are two kinds of coating materials for packaging printed matter: 1. Light film (bright film), the bright film itself is bright, and the surface of the color box is shiny after being coated with bright film. 2. Dumb film, which is a foggy surface; Matte matte surface after film covering. Bronzing At present, the bronzing method of color box is electrochemical aluminum foil, which mainly uses the method of heating and pressurizing to transfer the text of copy box to the surface of bronzed printing packaging paper. The colors are gold, silver, green, blue and laser, all of which are called bronzing. Hot stamping is characterized by clear pattern, beautiful appearance, bright color and wear resistance. In cigarette package printing, bronzing technology accounts for more than 85%, and it is also widely used in the production of commercial packaging. Can make the finishing point, highlight the theme, highlight the honor and so on. , especially trademarks, logo, corporate names and other places that need to be highlighted.

This technology has the lowest cost in post-press surface treatment. UV scrubbing is a post-press technology that uses ultraviolet rays to dry and cure ink, which requires UV ink containing photosensitizer and UV curing lamp. UV technology transfers patterns and characters to the surface of printed packaging paper after UV treatment, making it bright and special, especially suitable for use.
