1. After the net is stretched, why should the screen be pre-processed before the screen is made? What is included in the network pre-processing? A: The pre-treatment of the net is divided into roughening and degreasing. A. For polyester (PET) The weak polar material is roughened to increase the porous and unsmooth surface on its surface. The treated PET net can increase the bonding area with photosensitive materials, thus improving the adhesion of photosensitive materials on the net. B. Degreasing the screen on the screen plate is to remove oil stains, improve the affinity between the photosensitive material and the screen and the printing resistance times of the screen plate, and reduce the pinholes on the photosensitive layer during the making process of the screen plate. 2. How to make the average unevenness of the surface of the photosensitive layer (PZ value)Reduce? Answer: 1)The PZ value and size are related to the plate making method. Simple plate making method
