ABSTRACT:
Provided herein is a brushgraining process to improve the quality of lithographic printing plate substrate surfaces. In the process, the surface is brushed in an aqueous slurry comprising a mixture of particulates of alumina and quartz in a weight ratio range 95:5 to 5:95, with the particulates being in the size range of 1-20 microns. Such a process surprisingly lessens the number of scratches produced on the substrate surface than when compared to using alumina alone or quartz alone or a mixture of alumina and quartz with particle sizes higher than the range disclosed.
