ABSTRACT:
A ferromagnetic foil carrying a layer of a pressure sensitive adhesive for adhesive attachment to a printing plate to be used in a letterpress or flexographic printing operation. The ferromagnetic foil preferably is formed of a cold rolled steel having a thickness in the range of from about 0.001 inch to about 0.007 inch. The metal foil allows the printing plate to be adhered to the outer surface of a magnetized printing cylinder due to the magnetic attraction between the printing cylinder and the ferromagnetic foil. If the printing cylinder is not magnetized, but is formed of a ferromagnetic material, a flexible magnetic pad is applied to the outer surface of the cylinder, and the ferromagnetic foil-backed printing plate is then placed on the flexible magnetic pad. If the printing cylinder is formed of a non-ferromagnetic material, a flexible magnetic pad is first adhered to the outer surface of the cylinder, such as by an adhesive, and the foil-backed printing plate is then adhered to the flexible magnetic pad.
