Title (EN) SETTING INK USE LIMITS FOR A PRINTING SYSTEM
(FR) RÉGLAGE DE LIMITES D'UTILISATION D'ENCRE DESTINÉES À UN SYSTÈME D'IMPRESSION
Abstract:
(EN) An example method of setting ink limits for a printing system is described. The method involves printing a first set of color ramps. Each color ramp has test areas which are printed based different Neugebauer Primary Area Coverage (NPac) vectors. A test area for each color ramp is indicated that meets an image quality metric and Neugebauer Primary ink use limits are set based on these test areas. A second set of color ramps, for combinations of the set of available Neugebauer Primaries, is then printed, The test areas for each ramp are defined by monotonically-varying vector element values for one Neugebauer Primary in a combination and the second set of ramps are defined by monotonically-varying vector element values across said ramps for another Neugebauer Primary in the combination. Test areas are then indicated again for the second set of color ramps to set ink use limits for the printing system.
(FR) L’invention concerne un procédé illustratif de réglage de limites d'encre pour un système d'impression. Le procédé comprend l’impression d’un premier ensemble de rampes de couleurs. Chaque rampe de couleurs comporte des zones de test qui sont imprimées sur la base de différents vecteurs de couverture de zone primaire Neugebauer (NPac). Une zone de test pour chaque rampe de couleurs qui satisfaisait une mesure de qualité d'image est indiquée et des limites d'utilisation d'encre primaire Neugebauer sont définies sur la base de ces zones de test. Un second ensemble de rampes de couleurs, pour des combinaisons de l'ensemble de couleurs primaires Neugebauer disponibles, est ensuite imprimé. Les zones de test pour chaque rampe sont définies par des valeurs d'élément vecteur variant de manière monotone pour une primaire Neugebauer dans une combinaison et le second ensemble de rampes est défini par des valeurs d'élément vecteur variant de manière monotone sur lesdites rampes pour une autre primaire Neugebauer dans la combinaison. Des zones de test sont ensuite de nouveau indiquées pour le second ensemble de rampes de couleurs en vue de régler les limites d'utilisation d'encre pour le système d'impression.
