Title (EN) DETECTING PRINTING DEFECTS
(FR) DÉTECTION DE DÉFAUTS D'IMPRESSION
Abstract: front page image
(EN)A method for detecting printing defects includes, with a physical computing system (100), creating a matched reference image (500) from a digital image (300), colors of said matched reference image (500) being closer matched to a scanned image (302) of said digital image (300). The method further includes, with said physical computing system (100), determining a color difference between corresponding points on said matched reference image (500) and said scanned image (302); and with said physical computing system (100), identifying points that have said color distance greater than a predefined threshold as potential defects.
(FR)L'invention concerne un procédé de détection des défauts d'impression ; qui inclut un système informatique physique (100) créant une image de référence de comparaison (500) obtenue à partir d'une image numérique (300), les couleurs de ladite image de référence de comparaison (500) étant en correspondance avec une image scannée (302) de ladite image numérique (300). Le procédé inclut également, avec ledit système informatique physique (100), la détermination de l'écart de couleur existant entre des points correspondants de ladite image de référence de comparaison (500) et ladite image scannée (302) ; et, avec ledit système informatique physique (100), l'identification des points affichant un écart de couleur supérieur à un seuil prédéfini comme des défauts potentiels.
