Abstract
A printing plate is made by coating a metal substrate with a polymer layer having an outer surface, coating the polymer layer with solid particles having an average particle size of less than about 30 microns, and compressing the solid particles so that most of them are below the polymer layer outer surface. The solid particles are preferably alpha-alumina particles having an average size of about 1-10 microns. The printing plate has improved wear resistance.
