Abstract

Bei einem Verfahren zur Korrektur des durch farbspaltungsbedingte Oberflächeneffekte verursachten Messfehlers bei der farblichen Ausmessung eines Druckbogens an einer laufenden Druckeinrichtung wird der Druckbogen punktweise fatoelektrisch abgetastet und aus den Abtastsignalen (1) der Abtastpunkte werden Farb- und/oder Dichtemesswerte (3) gebildet. Diejenigen Abtastpunkte werden identifiziert, welche eine einen Grenzwert (IG) übersteigende Helligkeit aufweisen, und die Messwerte werden anhand der identifizierten Abtastpunkte korrigiert. Im Besonderen werden dabei die Abtastsignale der identifizierten Abtastpunkte bei der Bildung der Farb- und/oder Dichtemesswerte nicht berücksichtigt.
