LITHOGRAPHIC SUBSTRATE AND ITS PROCESS OF MANUFACTURE ABSTRACT Lithographic printing substrates ordinarily require a mechanical or chemical graining of aluminum surfaces. Such substrates are difficult and expensive to make. It has been found that lithographically suit- able substrates can be prepared by the firing of monobasic phosphate solutions with or without dispersed particles therein. The presence of reactive metallic oxides enhances the properties of the surface.
