Abstract
Dispositif de contrôle pour l'évaluation densitométrique de feuilles d'impression comportant des bandes de contrôle d'impression imprimées sur elles. Dans un support commun 4, sont disposés avec des distances entre eux pouvant être choisies, et en formant entre eux des interstices, des densitomètres 7 servant exclusivement à la mesure de la densité de pleine teinte que, dans tous ces interstices ou dans certains d'entre eux pouvant être choisis à volonté, peuvent être insérés des densitomètres 8 de mesure des valeurs de pleine teinte et/ou de teinte de trame nécessaires à la combinaison mathématique en grandeurs caractéristiques d'appréciation de qualité. Application notamment au contrôle de tirages en couleur.
