ABSTRACT:
An electrophotographic printing device having an arcuate photoconductive member (12) includes a flat screen member (32) that is spaced apart from the arcuate photoconductive member (12). A plurality of arcuate opaque lines are disposed on the screen member (32) such that the plurality of arcuate opaque lines are centered along the longitudinal axis thereof. Each of the lines is dimensioned such that it represents the mirror image of the shadow on the photoconductive member that would exist if a straight line were disposed on the screen at the same position.
