Abstract

An apparatus for treating photopolymer printing plates, which have already been exposed, with liquid media, in which the plate, mounted on a vertically movable holder, can be moved up and down between an upper loading and unloading chamber and a lower treatment chamber, separated from the upper chamber by a partially open partition, and in which upper and lower rim elements of the plate holder seal the aperture in the partition in a vapor-tight manner when the plate holder is in its terminal positions.
