Abstract

A plate cylinder for a sleeve-type printform, particularly an aluminum offset printform, with a ramp-like transition piece as a guide surface for the mechanical expansion of the sleeve-type printform onto the larger cylinder diameter. At least the surface area of the plate cylinder that is covered by the ramp-like transition piece has a highly wear-resistant and pressure-resistant slide surface of a material different from the remaining surface material of the plate cylinder to prevent abrasion when the printform is slipped onto the plate cylinder.
