CORRECTION FOR GRAVURE PRINTING PLATE

摘要

Gravure printing plates are corrected by applying a physical resist, usually an elastomeric polymer composition, to the tops of the cell walls in the area to be corrected, deepening the cells in that area using a jet of abrasive particles in a fulid and then removing the resist. The jet usually comprises an abrasive in water. The process is particularly suitable for the correction of gravure plates having an epoxy resin surface.
