Title (EN) METHOD FOR IMPROVING PRINTING PERFORMANCE FOR PRINTERS AND A DEVICE FOR ACCOMPLISHING THE METHOD
(FR) PROCEDE D'AMELIORATION DES PERFORMANCES D'IMPRESSION D'IMPRIMANTES ET DISPOSITIF DE MISE EN ×UVRE DU PROCEDE
Abstract: front page image
(EN)Method and device for improving the printing performance of electro-graphic printers, in which are produced a latent electrical charge pattern of electric signals by means of an electrode matrix or the like, which temporarily produces electrical fields for attraction of pigment particles (11) towards an information carrier (7). The electrodes (1, 2) of the electrode matrix during at least a part of the break time between the activation periods are exposed to a field of force which transports the pigment particles (11) in a direction from the electrodes.
(FR)L'invention concerne un procédé et un dispositif destinés à améliorer les performances d'impression d'imprimantes électrographiques, consistant à produire une configuration de charge électrique latente de signaux électriques, au moyen d'une matrice d'électrodes ou analogue, ce qui produit temporairement des champs électriques attirant des particules de pigments (11) vers un support d'informations (7). Lesdites électrodes (1, 2) de ladite matrice d'électrodes, pendant au moins une partie du temps de rupture entre les périodes d'activation, sont exposées à un champ de force transportant lesdites particules de pigments (11) dans un sens donné à partir des électrodes.
