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. CA 02215274 1997-09-10

Plaque d'impression obtenue par revêtement d'un substrat métallique avec une couche polymérique comportant une surface externe, par enrobage de la couche polymérique avec des particules solides d'un diamètre moyen inférieur à 30 microns, et compression des particules solides de telle façon que la plupart d'entre elles se situent en-dessous de la surface externe de la couche polymérique. Les particules solides sont de préférence des particules d'alpha-alumine d'une taille moyenne de 1 à 10 microns. CA 02215274 1997-09-10.
