ABSTRACT:
Disclosed is a manufacturing process of a printing plate material comprising a boehmite treated aluminum support, and provided thereon, an image formation layer containing water soluble resins or water dispersible resins, the process comprising the steps of surface roughening an aluminum plate, anodizing the surface roughened aluminum plate, boehmite treating the anodized aluminum plate to produce the boehmite treated aluminum support having boehmite protrusions with an average height of from 30 to 200 nm and an average base size of from 10 to 100 nm, coating a coating solution for the image formation layer on the resulting aluminum support to form a coated layer, and drying the coated layer to form the image formation layer on the aluminum support.
