ABSTRACT:
A lithographic plate processor (10) includes developer apparatus (12) and chemical distribution apparatus (14, 15). The developer apparatus (12) insures a uniform spreading of the developer over the exposed surface of a lithographic plate traveling through the processor. The developer apparatus (12) includes a pair of spreading members (40, 42) which are pivotally connected to each other by a parallel linkage (44). The parallel linkage (44) in turn is pivotally mounted to a subframe (46). A mechanism is provided for rotating a shaft (94) which drives a linkage to create an oscillating motion in the spreading members (40, 42) to uniformly spread the developer over the surface of the lithographic plate. The chemical distribution apparatus (14, 15) includes a tank (32) in which an agitating bar (38) is provided. The tank is mounted for oscillation and has a plurality of apertures (138) formed in the front wall (130) thereof to distribute chemical from within the tank to a lithographic plate below. The agitating bar (38) acts to agitate the chemical and a portion of the bar may be raised off the interior surface of the tank to enhance the agitation. The top portion of the tank may also be sloped towards the front wall (130) so that the agitator bar (38) further acts to increase the pressure driving the chemical through the apertures (138).
