Abstract (en)
[origin: WO8300844A1] Lithographic printing substrate ordinarily require a mechanical or chemical graining of aluminum surfaces. Such substrates are difficult and expensive to make. It has been found that lithographically suitable substrate 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.
