Document Type and Number:
WIPO Patent Application WO/2013/118620
Kind Code:
A1
Abstract:
Provided are a paper-polishing method and a paper-polishing device configured to prevent any incidence of doctor-blade-induced scratching, adhesion of soiling, or other adverse events during printing after a plate has been manufactured. A paper-polishing method in which a paper-polishing device of a fully-automated gravure plate-making processing system is used, a polishing cloth being pressed on the circumferential surface of a plate-making roll, and polishing indentations due to the coated abrasive are formed on the non-coverage portions of a plate surface at a predetermined angle relative to the normal to the circumferential surface of the plate-making roll. The polishing indentations include those at an inclination of ±46-90°.
