Self-adhesive label printing is a specialty printing process. Generally, printing and post-printing processing are completed in one go on a label printing machine, meaning multiple processing steps are completed at several stations on a single machine. Because it's an inline process, controlling the quality of self-adhesive label printing is a comprehensive printing and processing issue. It requires comprehensive consideration and implementation of material selection, equipment configuration and control, and process route formulation. Furthermore, it's crucial to track the application of the labels at the customer's site to further improve product quality. Printing equipment is mainly divided into rotary and flatbed types, using letterpress printing.
When selecting raw materials, it is essential to choose high-quality self-adhesive materials with all physical and chemical indicators meeting standards. Avoid using expired or unstable products. While the latter may be cheaper, their unstable quality leads to high consumption in each process, and can even cause equipment malfunctions. This wastes not only raw materials but also significant manpower and resources. The resulting processing cost of the finished labels may not be low, and more seriously, it could lead to customer returns or even the loss of customers.
