The authoritative experts below will give you the effect of washing powder in lithographic printing: 1. It can clean the plate. In lithographic printing, it is a common problem that the ps version is dirty. Moisturizing powder is helpless to figure out. When encountering this kind of scenery, why not use a little washing powder, separate a certain amount of washing powder with the cleaning liquid or solidify, and use a sponge to slightly wipe the dirty parts of the printing plate, and in the process of wiping Pay special attention, if the dirty part of the printing plate is a flat screen, the amplitude of recovery is smaller, otherwise the printing plate is likely to be scratched. 2.
