Abstract
A process for producing a support for a lithographic printing plate is disclosed, comprising mechanically graining a sheet for the support with abrasive grains which have sharp-angled tips having a radius of not more than 20 .mu.m. The process is suitable for mass production, and the lithographic printing plate produced from the resulting support is excellent in stain-resistance and printing durability.
