ABSTRACT:
An apparatus and a method for making a lithographic printing plate by silver salt diffusion transfer processing, comprising means for informationwise exposing an imaging element (5) comprising on a support in the order given a silver halide emulsion layer and a layer comprising physical development nuclei: means for processing a thus obtained informationwise exposed imaging element using a processor comprising a developing unit (120), the developing unit comprising (i) a tank holding an alkaline processing liquid, (ii) a plurality of guide rollers (50) and guide plates (121 to 126) for transporting and guiding the informationwise exposed imaging element in a transport direction X through the alkaline processing liquid characterised in that at least one of the guide plates (121 to 126) exhibits a plurality of apertures (150) to allow the alkaline processing fluid to pass evenly near the surface of the imaging element.
