PRINTING BLANKET CONSTRUCTION AND METHOD FOR REDUCING CORROSION OF PRINTING BLANKET CYLINDERS

摘要

A printing blanket construction and method for reducing corrosion of printing blanket cylinders is provided. The printing blanket (11) comprises at least one base ply (12, 13) and a surface layer (10) on one surface of the base ply wherein the opposite surface of the base ply (12) is adapted to contact the blanket cylinder. The printing blanket includes a metal or alloy having a greater negative electrochemical potential in the electromotive series than the metal comprising the surface of the blanket cylinder. The preferred metal for use may be selected from the group consisting of zinc, magnesium, cadmium or aluminum. The metal may be introduced onto the opposite surface of the base ply (12) in the form of a metal sheet, by coating, or in particle form through the use of a coating. After introduction of the metal, the opposite surface of the base ply is preferably ground to produce a smooth, nontextured surface.
