Quality Control of Silk Screen Printing Process for Cosmetic Packaging

Introduction: Screen printing is very common in the manufacture of cosmetic packaging materials. The process of screen printing is relatively simple. However, there are many factors that affect product quality in the entire screen printing process, which directly affect the quality of the final product. For example, improper equipment, printing plates, inks, post-processing and operating skills will cause printing failures, and most of them are the result of the cross-influence of multiple factors. This article shares the relevant content of screen printing quality control for your reference:

The screen printing process is that the ink leaks through some of the mesh holes of the screen and leaks on the substrate, and the mesh holes of the rest of the screen are blocked, so the ink cannot pass through. When printing, the ink is poured on the screen. Without external force, the ink will not leak through the mesh holes to the substrate by itself. When the scraper scrapes the ink with a certain pressure and tilt angle, it will be transferred through the screen to the substrate below to achieve image replication.
