ABSTRACT:
A printing material guiding surface structure, preferably for cylinders or cylinder dressings of printing machines has a surface structure which facilitates improved sheet guiding in that the friction forces at the contact points of the printing material and the surface structure are increased. This is achieved by utilizing elevated structure elements which are arranged on a substrate, and which have a bearing surface with a multiplicity of depressions that increase the surface roughness thereof and have good ink repelling characteristics.
