METHOD FOR REDUCING STRIATIONS IN ELECTROSTATIC PRINTING

A 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 multi...

Summary:A 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. L'invention concerne un procédé de réduction des stries en impression électrostatique consistant à faire varier les séquences d'activation des plaques dans une configuration de groupes de pointe sur la tête d'écriture d'une imprimante électrostatique afin d'éliminer visuellement les effets de stries en séquences. Cette variation, combinée à d'autres techniques, réduit au minimum les stries de multiplexage affectant négativement la qualité d'impression de données sortant d'imprimantes électrostatiques rapides à grande largeur.
