Definitions

  • the present invention relates to a printing blanket construction, and more particularly, to a printing blanket construction and method for reducing corrosion of a blanket cylinder.
  • the type of blanket referred to herein is used primarily in offset lithographic printing, but may also find utility in other fields of printing.
  • a rotary cylinder is covered with a printing plate which has a positive image area receptive to oil-based inks and repellent to water, and a background area where the opposite is true.
  • the printing plate is rotated so that its surface contacts a second cylinder covered with a rubber-surfaced ink-receptive printing blanket.
  • the ink present on the image surface of the printing plate transfers, or offsets, to the surface of the blanket.
  • Paper or other sheet stock to be printed is then passed between the blanket-covered cylinder and a rigid back-up cylinder to transfer the image from the surface of the blanket to the paper.
  • the working surface of the blanket which contacts the ink is typically an elastomeric layer of natural or synthetic rubber which is applied over the base layer or layers.
  • the base layer and working surface are laminated together using suitable adhesives.
  • the printing plate and blanket cylinders are subject to corrosion and rust as a result of exposure to inks, water, and chemicals and solvents used to clean the machinery.

  • the present invention meets that need by providing a printing blanket construction and method in which a protective metal is included in one or more layers of the blanket or on the back side of the printing blanket.
  • the protective metal in or on the blanket functions to reduce corrosion of the metal on the blanket cylinder by acting as an anode material which preferentially is sacrificed.

Le métal de préférence utilisé peut être choisi dans le groupe se composant de zinc, de magnésium, de cadmium ou d'aluminium. Le métal peut être introduit sur la surface opposée de la couche de base (12) sous la forme d'une feuille métallique, par couche, ou sous forme de particules par enduction. Après application du métal, la surface opposée de la couche de base est de préférence poncée afin d'obtenir une surface lisse, non structurée.
