According to the invention, at least one surface property of the invention, namely the overall surface energy of the blanket, the surface energy with a polar character of the blanket or the average roughness of the blanket varies on the outer surface of the blanket crosswise. The invention is applicable for any indirect printing process, especially offset printing as function.

Blanket with variable surface properties for a printing machine

A lithographic layer for a printing blanket and the printing offset blanket incorporating same, wherein the lithographic layer is made from a thermoplastic material with a polar character providing a maximum transfer of printing ink from the blanket to the paper and is easily washable thereby resulting in a minimum ink consumption.
