Abstract
A process for producing an aluminum support for a lithographic printing plate is described, which comprises jetting a high-pressure liquid from at least one nozzle at a high rate, joining the jetted stream with a slurry containing a fine powder of an abrasive spouted from at least one spout, and directing the resulting mixed stream to strike against a surface of an aluminum plate to carry out cleaning and sandblasting at the same time.
