Production process of roll self-adhesive stickers?
The wide application of self-adhesive labels and the continuous development of label varieties naturally promote the development of label printing technology. Self-adhesive is a kind of printing material, and self-adhesive labels are divided into two categories: one is paper self-adhesive labels, and the other is film self-adhesive labels.
The printing process of roll stickers is as follows.
Unwinding: There is no tension change when unwinding, so no adjustment is required. When in use, it is flattened and flattened on the labeling machine, and the unwinding speed is slow. Since this type of equipment does not have paper positioning and proofreading equipment, the end face of the roll paper is required to be regular to ensure the accuracy of overprinting and printing quality.
Printing: Flattening is suitable for printing small areas and simple patterns, such as price tags and barcodes. Circular flat is suitable for label printing with solid and general graphics, and can be used for simple color halftone printing. Rotary printing is suitable for all kinds of graphic label printing, especially for multi-color halftone label printing.

Polishing: Printing is to coat a layer of varnish on the surface of the ink, the purpose is to protect the ink layer, moisture-proof and waterproof, and improve the surface gloss. It can replace the lamination process and choose the UV drilling method.
Laminating: Laminating on paper or film materials, the purpose is to protect the ink, waterproof and moisture-proof, increase the strength of the label and the three-dimensional effect of the pattern. The lamination is divided into a liner lamination and a linerless lamination. The latter is now widely used because of its low cost. According to the process requirements, there are two kinds of composite transparent film and matt film, the former is widely used.
Die-cutting: The die-cutting of self-adhesive labels is a half-cutting process, that is, only the appearance information is cut through, and the backing paper is retained. Paper delivery: paper cutting, origami.
General label printing is done through these steps. Some will add some bronzing, punching and other processes.
