  • Hydrophilized support for planographic printing plates and its preparation
    Patent number: 6105500
    Abstract: A method for preparing a substrate for a planographic printing plate is disclosed. A liquid that contains water; a soluble alkali metal silicate, preferably sodium silicate; and a dispersed particulate material is coated on a substrate, preferably aluminum or an aluminum alloy, to produce a hydrophilic layer on the substrate. A layer of image material may be coated over the substrate to produce a planographic printing plate. In one embodiment the liquid contains a mixture of two particulate materials: alumina and titanium dioxide.

  • Method of thermally spraying a lithographic substrate with a particulate material
    Patent number: 5881645
    Abstract: A method of making a light sensitive printing plate such as might be used in lithography, comprises creating a surface layer on substrate base material by depositing particulate coating material on the base material using a dry deposition technique, the surface layer being formed from particles whose size is less than about 15 .mu.m, and creating an image layer on the deposited surface layer so that the surface layer is located intermediate the base material and the image layers.
