A printing blanket and method of reducing corrosion and abrasion of printing blankets and printing blanket cylinders is provided. The printing blanket includes a metal base ply having first and second surfaces, a surface layer on the first surface of the base ply, and a polymer on the second surface of the base ply. The polymer functions to protect the metal base ply as well as a blanket cylinder surface from abrasion and exposure to moisture and corrosive agents used during a printing process. The polymer preferably comprises ethylene vinyl acetate copolymers, nylon, polyester, polyurethane, or polyethylene. The polymer may be applied to the in the form of an emulsion which is coated or sprayed onto the base ply, or the polymer may be provided in the form of a film or sheet which is adhered to the base ply with an adhesive. Preferably, the polymer includes corrosion inhibiting additives which are released when the blanket is compressed during a printing operation, further reducing corrosion.

Printing blanket and method for reducing corrosion and abrasion of printing blankets and blanket cylinders

A printing blanket adapted to be used with a magnetic printing cylinder including a gap extending longitudinally along the outer surface thereof is provided. The printing blanket includes a plurality of plies with a magnetic backing ply which is magnetically adhered to the printing cylinder. The printing blanket is positioned on the printing cylinder such that an end of the printing blanket is bent over an edge and inwardly into the gap. The opposite end of the printing blanket is mounted substantially adjacent the opposite edge of the gap. A tensioning roll or similar device to which the printing blanket may be attached can be disposed in the gap to secure the printing blanket to the printing cylinder more firmly.

A printing blanket construction and method and apparatus for making the same are provided, the blanket construction comprising an outer layer formed mainly of polymeric material and having an outer printing surface for carrying liquid printing ink or the like for printing purposes or the like, the outer printing surface having a plurality of separate ink wells interrupting the same in a closely spaced apart generally uniform pattern thereof throughout substantially the entire printing area thereof and with a relatively large number of the wells each having a mouth opening at the printing surface that has a substantially straight-line length across the largest portion thereof of approximately 3 microns to approximately 65 microns.
