ABSTRACT:
Disclosed herein are a process and apparatus for developing photopolymer plates which are useful for flexographic printing on account of their rubber-like elasticity, capability for development by water washing, and good ink resistance. The process and apparatus are designed to circulate by force the washout solution during the development operation in order to minimize the aggregation of photopolymer particles suspending in the washout solution and to completely catch scum which occurs when the unexposed part of the polymer plate is rubbed off in the washout solution.
