Title
(EN) AUTOMATIC REGISTRATION ADJUSTMENT
(FR) REGLAGE AUTOMATIQUE DE REPERAGE
Abstract
(EN)
A method for registration of print separations in a printer comprising: (a) printing a first pattern, for which at least one image characteristic varies relatively weakly with misregistration, using at least one of first and second separations; (b) printing a second pattern, for which said image characteristic varies relatively strongly with misregistration, using said first and second separations; (c) determining at least one image characteristic for the first and second patterns and (d) correcting the mutual registration of the first and second separations responsive to a difference in the determined at least one characteristic for the first and second patterns.
(FR)
L'invention concerne un procédé de repérage de séparations d'impression dans une imprimante, qui consiste à: (a) imprimer un premier motif, pour lequel au moins une caractéristique d'image varie relativement faiblement avec le défaut de superposition, à l'aide d'au moins une des première et seconde séparations; (b) imprimer un second motif, pour lequel ladite caractéristique d'image varie fortement avec le défaut de superposition, à l'aide desdites première et seconde séparations; (c) déterminer au moins une caractéristique d'image pour les premier et second motifs; et (d) corriger le repérage réciproque des première et seconde séparations en réponse à une différence dans ladite caractéristique déterminée pour les premier et second motifs.
