Process for desensitizing lithographic printing plates |
摘要 |
A process for desensitizing lithographic printing plates is described. The gum for the process comprises an aqueous solution containing a film-forming starch derivative modified with polyoxyethylene or a polyoxyethylene-polyoxypropylene copolymer. The gum reduces the number of spoiled copies printed and the amount of staining on non-image areas.
