ABSTRACT:
Apparatus for printing indicia on corrugated board in particular is provided. The apparatus includes a printing plate made of a polymer material which has a number of advantages over conventional printing plate materials. However, because the polymer material is somewhat resilient and exhibits a degree of yieldability, and dimensionally-stable sheet is provided, which is either on the back of the material or molded into the material near the back. The printing plate is adhered to a mounting sheet which is also dimensionally stable and is mounted on a printing plate cylinder. A resilient or compressible layer or pad is affixed to the back of the mounting sheet, between the mounting sheet and the printing cylinder, and is of a size at least equal to that of the printing plate. The pad provides additional compressibility and resiliency to enable the printing plate to effectively print indicia on corrugated board and also raises the printing surfaces of the printing plate farther from the surface of the printing plate cylinder.
