METHOD FOR REPEATEDLY REUTILIZING AQUEOUS ELUATE OF PHOTOSENSITIVE FLEXOGRAPHIC PRESS PLATE

摘要

PROBLEM TO BE SOLVED: To provide a repeatedly reutilizable aqueous eluate of a photosensitive flexographic plate. ;SOLUTION: A photosensitive flexographic plate is eluted (preparation) in a flexographic printing press at the room temperature or a temperature higher than the room temperature, the prepared press plate is taken out, an eluate is left stationary, and a floated aqueous gelatinous body is removed in the following methods. (1) A sheet-like object is left in contact with the surface of the floated gelatinous body, the gelatinous body is stuck to the sheet surface, and a photosensitive elastomer composition is removed. (2) A container storing the eluate containing the floated gelatinous body is pressurized from below, or the eluate or the constituent of the eluate is supplied and overflown, and the photosensitive elastomer composition is removed.;COPYRIGHT: (C)1997,JPO
