Self-adhesive refers to prints printed on a composite material made of paper, film or other special materials, with adhesive on the back and silicon-coated protective paper as the base paper: In product form The front side is a composite single-page print, and the back is coated with adhesive, which can be bonded where the customer needs it to be bonded. In terms of printing methods, self-adhesive printing usually uses screen printing. In recent years, due to the development of offset printing technology, self-adhesive printing also uses offset printing. Film output and plate making need to be carried out before printing. In terms of post-press processing technology. Necessary cutting is required, and when the design has special needs, some special processing techniques will be added, but generally the complexity is not high. Self-adhesive label printing, because the main printing products are mainly product labels and signs, is also called trademark printing. Self-adhesive printing uses special composite paper. This paper must be pre-made by a paper processing factory. Generally, a layer of self-adhesive is applied to the back of the substrate and adhered to an easily peelable release paper. After printing, use a knife line to stamp, peel off the excess blank, and leave a certain shape of printed matter on the release paper. When using, peel off the finished product and paste it on the product or packaging.

In the 1930s, self-adhesive materials were first used in the United States. Due to the expanding demand for this special composite material, self-adhesive printing has gradually evolved into an independent printing field. There are more and more companies specializing in self-adhesive label printing. As far as our country is concerned, the unprecedented development of the printing industry in terms of production scale, technical level, market space, etc. has driven the development of self-adhesive printing and reached unprecedented levels.
