Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Korrektur lokaler, maschinenbedingter Färbungsungleichförmigkeiten an Rotationsdruckmaschinen, bei dem die nachfolgenden Verfahrensschritte durchlaufen werden:The invention relates to a method for correcting local, machine-related Coloring irregularities on rotary printing machines, in which the following Process steps are followed:

Zunächst erfolgt die Ermittlung des Einfärbeverhaltens der Druckwerke einer Mehrfarbenrotationsdruckmaschine mittels Testformen. Die Färbungsungleichförmigkeiten an den Testformen werden an der Druckvorstufe übertragen. Anhand der Daten zu den Färbungsungleichförmigkeiten der Testformen werden die Rastertonwerte der Farbauszüge einer Druckform derart modifiziert, daß die Färbungsungleichförmigkeiten lokal abhängig vom Ort ihres Auftretens im Druck auf den Druckform- bzw. -filmen vorgehalten werden.First, the inking behavior of the printing units is determined Multi-color rotary printing machine using test forms. The coloring irregularities on the test forms are transferred to the prepress. Based on the data on the Color irregularities in the test forms become the halftone values of the color separations modified a printing form in such a way that the color irregularities locally dependent from the place of their appearance in the print on the printing form or films.
