Self-adhesive is divided into one type of printing material. Self-adhesive labels are divided into two categories. Different types of materials and labels for different purposes use different processes. Then the processing flow of self-adhesive label printing is How is it? Let's take a look at the following.
First of all, when printing and making self-adhesive labels, choose a self-adhesive label with the right color. If the label content only needs some text during production, you can directly choose to use digital printing, that is, directly transfer the file to the computer, and then engrave on the label with a cutting plotter. Can make an ideal self-adhesive label. If the self-adhesive label requires more patterns, you can use an inkjet printer to paint on the label, and use an engraving machine to cut.
Unwind
(1) Intermittent: There is no tension change when the roll paper is unrolled, so no adjustment is needed. Used in flat and round flat labeling machines, the unwinding speed is slow. Since this type of equipment has no paper positioning and correction device, the end of the roll paper is required to be clean to ensure accurate overprinting during printing.
(2) Continuous type: used in the round-to-round labeling machine. Because the paper has tension changes when the diameter and speed of the roll paper changes, this device has an automatic or manual tension control mechanism, as well as a roll paper correction device to ensure smooth paper feeding and print quality.

Flat pressing: suitable for small area, simple pattern printing, such as price labels, bar codes, etc. Round flattening: suitable for label printing with solid and general patterns, and can be used for simple color screen printing. The round press is suitable for all kinds of graphic label printing, especially for high-end color mesh label printing. UV printing: In the above three printing methods, after UV drying, film stickers can be printed.
Glazing
On-site glazing: Coat a layer of varnish on the surface of the ink. The purpose is to protect the ink layer, prevent moisture, water and improve the surface gloss. It can replace the laminating process and adopt the UV drying method.
Laminating
Laminating on paper or film materials, the purpose is to protect the ink, waterproof, moisture-proof, increase the strength of the label, and increase the three-dimensional sense of the pattern. Laminating is divided into bottomed paper laminating and bottomless paper laminating. Due to the low cost of the latter, it is currently widely used. According to the requirements of the process, there are two kinds of composite transparent film and matt film, the former is more commonly used
