Abstract
An apparatus and method for controlling discharge devices used to image a planographic printing plate are disclosed. Imaging information is stored in a first memory while discharge correction data is stored in a second memory. The correction data is used to vary the intervals between imaging discharges to compensate for error between the sensed position of the printing plate with respect to a writing head and the actual position. Printing artifacts are visually minimized by staggering the imaging devices used to produce separation plates.
