ABSTRACT:
A lithographic printing plate precursor for use in a silver diffusion transfer system comprises a grained and anodized aluminum substrate having coated thereon a sol containing nuclei for precipitating silver from a silver complex. The substrate has an anodic weight (gm.multidot.m-.sup.2) to surface roughness (microns) ratio greater than or equal to 6. Printing plates produced from such precursors are less prone to corrosion and have improved printing life.
