Abstract

Disclosed is a reversal imaging process using liquid ink development, In this process, a gravure-like roller is con-structed from a transparent substrate having a substantially uniform pattern of lands and valleys. The exterior of this substrate is coated with a transparent conductive electrode and a thin photoconductive layer is thereafter deposited upon this electrode 1ayer- This gravure-like device is bias by connection of the electrode layer to a D-C. power source, the photoconductive surface of the device contacted with a source of liquid ink and brought in contact with a receiving sheets An image is projected through the transparent substrate there-by causing photo-activation of the photoconductive layer and resulting in the selective transfer of ink to the receiving sheet, The ink is only transferred from the gravure-like device to the receiving sheet in those areas corresponding to photo-activation of the photoconductive layer of the gravure-type device,
