Abstract

La présente invention concerne un dispositif pour système de mesure visuelle de couleur d'impression et de tolérance et un procédé pour son utilisation. Le dispositif est composé d'un corps (1) en forme de règle rectangulaire et d'une barre (2) de couleurs de contrôle. Le corps est une zone (3) de valeur de couleur d'un gris neutre, qui est formée de pourcentages de couleurs primaires respectives et de couleurs hypo-primaires respectives. Le corps et des ensembles multiples de blocs de couleurs interchangeables sur le corps sont tous des zones fonctionnelles comprenant des informations de teintes contrastées comme moyen de mesure visuelle et comportant en outre des zones d'informations de contrôle des couleurs qui peuvent contraster avec des limites supérieures et inférieures de valeur de couleur perçues par les yeux. Les zones d'informations de contrôle des couleurs donnent directement des informations de tolérance de teinte. La barre de couleurs de contrôle est agencée avec une série de zones fonctionnelles d'indication en liaison rapprochée servant au contrôle de l'alignement, les zones fonctionnelles sont agencées en parallèle et leur ordre correspond à celui du corps. Le dispositif est adapté à des processus d'impression mécaniques et numériques, applique une technologie de balance des gris et peut corriger rapidement et directement la valeur de couleur de point à point sans instrument de mesure, permettant ainsi de connaître la variation de la production dans le temps, réduisant les pertes et donnant lieu à un bon environnement de production avec un taux d'erreur minimal.
