METHOD FOR MANUFACTURE OF LITHOGRAPHIC OFFSET PRINTING PLATE BY SILVER SALT DIFFUSION TRANSFER METHOD

摘要

PURPOSE: To provide the method for manufacturing the offset lithographic plate by the silver salt diffusion transfer method by using rinse water. CONSTITUTION: The rinse water is brought into contact with a metal (i) group IB or IIB or VIII of the periodic table or an alloy (ii) containing at least one of the about metals or (iii) the salt containing the ions selected from one of the above metals before rinsing the exposed and developed image-forming material in at most <=20m<3> and/or before using of the rinse water exceeds 24 hours.
