Abstract

A device for the adjustment of the digital data stream that drives the modulators in an ionographic printing device. In particular, the device stretches strings of black image pixels to produce wider vertical lines and other fine details that may have been adversely affected due to modulator crosstalk. Moreover, the present invention is implemented in such a manner, so as to enable the end user to selectively define the magnitude of stretching to be applied to the strings of black pixels.
