Abstract

1. Inking and damping unit for offset printing presses with rubberised or the like inking and damping unit rollers which cooperate with further inking and damping unit rollers, particularly distributor rollers, which have a protective coat of a polyamide which is modified with metal powder characterised in that the further inking and damping unit rollers (4-6, 16, 20-22, 32 or 5, 6 11-15, 28-30, 32) have a modified protective coating (2) with a proportion of at least 15 volume % ink friendly particles preferably Cr-Ni steel, Cu, Cr particles in polyamide 11 (RILSAN), wherein the proportion of the ink friendly particles is chosen to be falling from roller to roller in the feed direction of the ink.
