Abstract:
The mechanical roughening of the surface of a printing plate substrate comprising aluminum or an aluminum alloy is carried out by wet brushing with the use of a cylinder brush 1 in which brush rows 2, 3 having bundles of organic fibers 22 and metal wires 33 are arranged side by side on the surface 7. The suspension used for the wet brushing contains from 5 to 80% by weight of abrasive particles in water.
