Abstract
A system and method of reducing striations in electrostatic printing is provided by varying plate firing sequences in a pattern of nib groups on the writing head of an electrostatic printer to visually mute the effects of sequence striations. This variation, in combination with other techniques, minimize multiplexing striations that affect adversely the print quality of data emerging from high speed, wide width electrostatic printers.
