Abstract
Description
Die Erfindung betrifft ein Verfahren zur Kompensation von Störmomenten in mindestens einem Druckwerk einer Rotationsdruckmaschine.The The invention relates to a method for the compensation of disturbance torques in at least one printing unit of a rotary printing press.
Für die Erzielung einer hohen Druckqualität ist die Lagegenauigkeit der in den einzelnen Druckwerken aufgebrachten Farbauszüge bzw. Teildruckbilder auf dem Druckbogen ein wesentliches Kriterium. Die Druckbilder müssen zur Erzielung einer hohen Detailschärfe mit möglichst geringen relativen Lageabweichungen zueinander übereinander gedruckt werden. Die Lagegenauigkeit wird durch die Passerdifferenz zwischen den Teildruckbildern, die in den einzelnen Druckwerken auf den Druckbogen aufgedruckt werden, charakterisiert. Passerdifferenzen entstehen durch zufällige und/oder systematische Abweichungen in der Synchronität der Rotationsbewegungen der Druckform- bzw. Platten-, Gummituch- oder Gegendruckzylinder in den Druckwerken, die zu relativen Verschiebungen der Teildruckbilder auf dem Bogen führen. Eine solche systematische Abweichung wird von den auf dem Plattenzylinder abrollenden Auftragwalzen verursacht. Der Plattenzylinder weist einen Plattenzylinderkanal zur Fixierung einer Druckform auf. Die Druckform wird von den Auftragwalzen während der Rotation des Plattenzylinders mit Feuchtmittel benetzt bzw. mit Druckfarbe eingefärbt. Beim Passieren des Plattenzylinderkanals, insbesondere der Kanalkanten von Kanalanfang und Kanalende, wird von den Auftragwalzen durch Störmomente die Rotationsbewegung des Plattenzylinders beeinflusst. Die Störmomente verursachen somit eine Passerabweichung, die die Druckqualität vermindert.For the achievement a high print quality the positional accuracy of the applied in the individual printing units color separations or partial printing images on the printed sheet a key criterion. The printed images must to achieve a high level of detail with the least possible relative positional deviations one above the other to be printed. The positional accuracy is determined by the registration difference between the partial print images in the individual printing units printed on the sheet, characterized. Registration differences arise by accidental and / or systematic deviations in the synchronicity of the rotational movements the printing plate or plate, blanket or impression cylinder in the printing units, resulting in relative shifts of the partial print images lead on the bow. Such a systematic deviation is from those on the plate cylinder rolling applicator rollers caused. The plate cylinder points a plate cylinder channel for fixing a printing plate. The Printing form is from the applicator rollers during the rotation of the plate cylinder with Wetting agent moistened or inked with printing ink. When passing the plate cylinder channel, in particular the channel edge of the channel beginning and end of the channel is from the applicator rollers by disruptive moments influences the rotational movement of the plate cylinder. The disturbance moments cause a registration error, which reduces the print quality.
Aus
der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zu entwickeln, welches mit geringem technischem Aufwand die Passerabweichungen in Druckwerken reduziert.Of the The invention is therefore based on the object to develop a method which with little technical effort the register deviations reduced in printing units.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den Merkmalen des 1. Anspruchs gelöst.According to the invention Problem solved by a method having the features of the first claim.
Die Erfindung hat den Vorteil, dass es durch die stetige Beaufschlagung des Plattenzylinders während eines Druckauftrages mit konstanten Kompensationsmomenten zu keinen Resonanzschwingungen kommen kann. Das Verfahren kompensiert einen Teil der auftretenden Störquellen und macht somit die Kompensation anderer Störquellen durch zusätzliche Regelungen leichter. Durch Ausführung der Messung vor jedem Druckbeginn werden die Messwerte dem aktuellen Zustand der Druckmaschine den Druckeinstellungen bei dem jeweiligen Druckauftrag angepasst. Das Verfahren besitzt keine Verzögerungszeit und kann somit die Störquellen schnell ausgleichen.The Invention has the advantage that it by the continuous admission of the plate cylinder during a print job with constant compensation moments to none Resonant vibrations can come. The method compensates for one Part of the occurring sources of interference and thus makes the compensation of other sources of interference by additional Regulations easier. By execution of the Measurement before each print start, the readings are the current Condition of the printing press the pressure settings at the respective Customized print job. The method has no delay time and can thus the sources of interference compensate quickly.
