Method of thermally spraying a lithographic substrate with a particulate material

摘要

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.
