ABSTRACT:
A washing device for an impression cylinder jacket in a sheet-fed offset two-sided printing press equipped with an impression cylinder installed with a jacket having a metal plate, a base layer formed to have concave-convex profile on the surface of the metal plate and a low surface energy resin layer formed on the base layer, includes a controller that executes a first control of causing a plate cylinder to contact with a blanket cylinder as well as the blanket cylinder to contact with the impression cylinder, and causes each cylinder to rotate under those contacts for a specified period of time while a cleaning unit is in contact with the blanket cylinder; and a second control of separating the plate cylinder from the blanket cylinder, and causing a water form roller and an ink form roller with the plate cylinder.
