Sticker printing and plate making process

Sticker printing varies depending on the type of printing paper. Currently, there are two types of printing paper:
1. Monomer structure of printing paper monomer or adhesive, such as water-coated active adhesive;

2. The printing paper is a surface substrate, coated with a pressure-sensitive glue, and a backing paper composite structure (also referred to as a self-sticking tape) coated with a release agent.

The former can be made with non-adhesive printing presses, and adhesive printing is usually referred to as the latter.

Self-adhesive printers can print, emboss, die, and cover film at the same time or continuously, which is very different from general printing. Printing methods include letterpress, offset, gravure, flexo, and screen printing.

4. Different printing inks: According to printing methods, drying methods, printing paper, ink types and adaptability are very different. Therefore, to select inks suitable for various methods, ink suppliers are required to provide satisfactory solutions.

The requirements for post-press processing are best equipped with the following features:

a) Film lamination device b) Hot stamping device c) Numbering device d) Rolling line device e) Drying device f) Shearing device g) Single-cutting device h) Surface coating (over-varnish) device
