QPrinting process of printing self-adhesive labels

Self-adhesive refers to the printed matter printed on the composite material with paper, film or other special materials as the fabric, with adhesive and silicon-coated protective paper as the back adhesive: back There are glued prints that can be glued to customers who need to be glued. In terms of printing methods, screen printing is usually used for printing on self-adhesive materials. In recent years, with the development of offset printing technology, offset printing is also used for printing on self-adhesive materials. Films and plates must be made before printing. In post-press processing technology. It must go through the necessary cutting. When the design has special needs, some special processing techniques will be added, but it is generally not difficult. For some self-pulling web printing models, it can be formed at the same time: printing, filming, bronzing, die-cutting and other processes.

Printing Self-adhesive labels belong to special printing. Generally, their printing and post-press processing are in The last time the labeling machine was completed, that is, multiple processing operations were completed on several stations of one machine. Because it is on-line processing, the quality control of self-adhesive label printing is a comprehensive printing and processing problem. It should be comprehensively considered and implemented from the selection of materials, the configuration and regulation of equipment, and the formulation of process routes, and tracked. The application of label products at customers in order to further improve the quality of label products.

When choosing raw materials, be sure to choose high-quality self-adhesive materials with qualified physical and chemical indicators, rather than products with expired or unstable physical and chemical indicators. Although the price of the latter is low, due to the unstable quality of such materials, the consumption of each process is large, and even the equipment cannot be processed normally, which wastes a lot of manpower and material resources while wasting raw materials. As a result, the processing cost of finished labels It is not necessarily low, and what is more serious is that it may be returned by customers or even lose customers.
