Abstract
A method for electrohydrodynamic printing wherein multiple colors are printed by discharging the receiving medium by reverse-sign corona discharge, then charging the receiving medium by corona discharge, and then printing the first color. The receiving medium is then discharged, and charged a second time by corona discharge. The process is repeated for each color used in the printing. As a result, the colors are printed in their intended locations without deflection even if the intended location is a dot of previously deposited color.
