Title:
SURFACE TREATING METHOD FOR ALUMINUM SUPPORT FOR PRINTING PLATE
Document Type and Number:
Japanese Patent JP3491245
Kind Code:
B2
Abstract:
PURPOSE: To stably manufacture a low-cost aluminum support having excellent printing performance without fill-in and contaminant by using an abrasive material having specific new Moh's hardness in a method for grain surface treating the support having the step of graining surface of the support by rubbing abrasive material slurry to the support by a polishing brush.
CONSTITUTION: In the surface treating step of an aluminum support for a printing plate, abrasive material slurry 4 applied to the surface of the aluminum support 1 is rubbed to the support 1 by a polishing brush 3. In this case, the abrasive material of the slurry 4 having 2 to less than 5 of new Moh's hardness is used. The abrasive material has particles in which the minimum piece/ maximum piece ratio of the three-dimensional size is 0.4 or more and the most acute angle is 45° or more and which is adapted for aluminum hydroxide. Further, the mean particle size of the material is 5 to less than 200μm, and the concentration of the slurry is 5 to less than 90wt.%.
