Abstract

The problem of crosstalk between adjacent electrodes in an ionographic print head in an ionographic printing system is known, and in some systems is manifested in a difficulty in producing vertical lines in printed images. For example, U.S. Patent No. 4,794,412 to Casey et al. teaches of just such a phenomenon and indicates a way to reduce the crosstalk effects by adjustment to the strobe and data voltages applied to the ionographic array gates which drive the head. Unfortunately, system latitudes prevent the reduction of the data and strobe voltages to a point which would assure the ability to eliminate crosstalk field effects and the associated problem of printing fine vertical structures. Accordingly, the present invention was developed to compensate for the crosstalk in an ionographic printing device, and in particular to provide consistent output of vertical structure within images created by an ionographic printing device.
