Title (EN) DENSITY CONTROL OF JET PRINTING DROPLETS
(FR) CONTROLE DE LA DENSITE DE GOUTTELETTES DE JET D"IMPRESSION
Abstract: front page image
(EN)Variation in colour intensity when printing areas of a surface (13) by a jet printing technique is achieved by (a) varying the voltage increment of the ramp incremental voltage applied to the droplet charging electrode (12) of a jet printer, and (b) simultaneously varying the spacing between consecutive droplet scans of the jet printer. In this way, a uniform matrix of equi-spaced droplets is printed over the area of the surface (13) and striated or non-uniform colour intensity in the printed area is avoided.
(FR)On fait varier l"intensite de la couleur lorsque l"on imprime des regions d"une surface (13) en utilisant une technique d"impression par jet en (a) faisant varier l"increment de tension de la tension incrementielle de rampe appliquee a l"electrode de charge des gouttelettes (12) d"une imprimante a jet, et (b) en faisant varier simultanement l"espacement entre des balayages consecutifs de gouttelettes de l"imprimante a jet. De cette maniere, une matrice uniforme de gouttelettes equidistantes est imprimee sur la zone de la surface (13), eliminant ainsi les stries ou les manques d"uniformite de la coloration dans la zone imprimee.
