The following are the common causes of errors in printing accuracy: 1. When making a multi-color overprint (half-tone printing) screen, the screen is dried at different temperatures, resulting in errors in printing accuracy. 2. The screen tension is low or the overprint (halftone) screen tension is different. 3. Drying using air blower, uneven drying of screen. 4. The use of too old, unsturdy and deformed screen frame plate making, due to poor screen frame stability caused by the deviation of the printed image (these problems can be detected with negative film). 5. When multi-color overprinting, the screen pitch used is inconsistent. 6. Deformation of glue scraping. 7. The size of the substrate changes due to certain factors.
