Abstract

In a printing machine, a photoconductive screen is positioned adjacent to a corona generating device, A light source illuminates an original document and the light reflected from the original document is transmitted to the screen making it conductive, The screen, in turn, controls the corona current density as a function of position, In this manner, the corona generating device charges the ink in the informational areas so that it becomes selectively transferable by pressure,
