There are two common plate-making methods for screen-printed signage panels: one is the indirect method, the plate-making with photosensitive film, especially the plate-making with capillary photosensitive film, the quality is very good; the second is the direct method, plate-making with diazo photosensitive adhesive. Photosensitive plate making is not as easy to learn and has higher printing durability than diazo photoresist making, but it requires a lot of skill and skill.
When making small-line thin-line signage panels, be sure to use film negatives, because the black areas of the film are very dark, and the transparent areas are very transparent, which can minimize the printing time and facilitate plate making.
