Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Korrektur von Registerfehlern bei einer Mehrfarbendruckmaschine (1) mit mehreren Einrichtungen (2, 2', ...) zur digitalen Erzeugung von Teilfarbenbildern (3, 3', ...), wobei Korrekturwerte ermittelt und den Winkelstellungen (4, 4', ...) mindestens eines Bildzylinders (5, 5', ...) zugeordnet und dadurch für die Steuerung der Erzeugung der Teilfarbenbilder (3,3', ...) auf letzteren berücksichtigt werden.The invention relates to a method and a device for correcting register errors in a multi-color printing machine (1) having a plurality of devices (2, 2 ', ...) for the digital generation of partial color images (3, 3 ',...), whereby correction values are determined and the angular positions (4, 4 ', ...) of at least one image cylinder (5, 5', ...) assigned and thereby for the control of the generation of the partial color images (3,3 ', ...) be taken into account on the latter.
Durch die Erfindung sollen Korrekturwerte zur Korrektur von Registerfehlern verfügbar gemacht werden, die in feiner Unterteilung Winkelstellungen von Maschinenelementen in wiederholbarer Weise zuordenbar macht.The invention is intended to provide correction values for the correction of register errors be made in fine subdivision angular positions of machine elements makes it assignable in a repeatable way.
Dies wird dadurch erreicht, daß Rundlauffehler (6, 6', ...; 8, 8', ...; 9) von Maschinenelementen (5, 5', ...; 7, 7', ...; 10), welche Einfluß auf das Register haben, ermittelt, ihren Winkelpositionen (4, 4', ...; 13, 13', ...; 14) zugeordnet und daraus die Korrekturwerte für die Steuerung der Erzeugung der Teilfarbenbilder (3, 3', ...) auf dem mindestens einen Bildzylinder (5, 5', ...) bestimmt werden. This is achieved in that concentricity errors (6, 6 ', ..., 8, 8', ..., 9) of machine elements (5, 5 ', ..., 7, 7',... 10 ), which influence the register, are assigned their angular positions (4, 4 ', ...; 13, 13', ..., 14) and from this the correction values for the control of the generation of the partial color images (3, 3 ', ...) on the at least one image cylinder (5, 5', ...) are determined.
