A: The screen printing mesh processing is divided into roughening and skim.

1. Coarse (PET) weakly polar materials are added to the surface to increase the porosity of the matte surface. Processed PET network can increase the combined area with the photosensitive material, thereby enhancing the photosensitive material in the online adhesion.

2. The screen on the silk screen printing mesh degreasing in order to remove oil, improve the affinity between the photosensitive material and the screen and screen printing times, reducing the screen in the production process of pinhole on the photosensitive layer.
