Abstract
Description
Die Erfindung betrifft ein Kurzfarbwerk für eine Rotationsdruckmaschine, enthaltend einen Druckformzylinder, eine den Druckformzylinder kontaktierende Farbauftragwalze und eine mit der Farbauftragwalze zusammenwirkende Rasterwalze, der eine Einrichtung zur Farbzuführung zugeordnet ist.The The invention relates to a short inking unit for a rotary printing press, comprising a printing form cylinder, a printing form cylinder contacting Ink application roller and one cooperating with the inking roller Anilox roller associated with a device for ink supply is.
Kurzfarbwerke sind schon seit langem bekannt. Diese Farbwerke weisen eine geringe Anzahl von Walzen auf. Wenn aber Farbwerke über wenige Spaltstellen verfügen, tritt aufgrund des geringen Schichtdickenausgleichs ein unregelmäßiger Verlauf der optischen Dichte auf. Ein gleichmäßig dünner Farbauftrag über die ganze Produktionszeit von wenigen μm ist neben der Schablonierfreiheit aber eine Grundbedingung für die Qualität des Druckprodukts.Short inking units have been known for a long time. These color works have a low Number of rolls up. But if inking over a few cleavages occur due to the low coating thickness compensation an irregular course of the optical density on. A uniformly thin paint over the whole production time of a few microns is beside the Non-stenciling but a basic condition for the quality of the printed product.

Bei allen Kurzfarbwerken besteht das Problem, einen möglichst glatten Farbfilm auf dem Druckformzylinder zu erreichen, um eine hohe Druckqualität zu erzielen.at All short inking units have the problem, one possible smooth ink film on the printing plate cylinder to reach a to achieve high print quality.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Kurzfarbwerk zu schaffen, welches einen dünnen, zeitlich konstanten, insbesondere gleichmäßigen Farbfilm erzeugt. Damit soll ein Kurzfarbwerk auch für die Herstellung hochwertiger Drucke einsetzbar sein.Of the Invention is therefore based on the object of a short inking unit create, which is a thin, temporally constant, in particular produces uniform color film. This should be one Short inking unit also for the production of high-quality prints be usable.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen ausgeführt.According to the invention the object by a device having the features of the first claim solved. Advantageous embodiments are in the subclaims executed.
Die Erfindung hat den Vorteil, dass eine hohe Gleichmäßigkeit des Farbfilms auf dem Druckformzylinder erreicht wird. Störende Effekte, wie Schablonieren, Streifenbildung, Butzenbildung und Moirebildung, werden verringert. Dies führt zu einer hohen Druckqualität.The Invention has the advantage that a high uniformity the color film is achieved on the printing form cylinder. disturbing Effects such as stenciling, banding, slug formation and moire formation, are reduced. This leads to a high print quality.
Die zusätzlichen Farbwerkwalzen können gegenüber der Farbauftragwalze vergleichsweise klein dimensioniert werden. Dadurch wird immer noch eine kompakte Bauform des Kurzfarbwerkes gewährleistet.The additional inking rollers can be compared the inking roller are dimensioned comparatively small. This still ensures a compact design of the short inking unit.
Das vorgeschlagene Kurzfarbwerk lässt sich sowohl bei Druckverfahren, bei denen ein Feuchtmittel zum Einsatz kommt, als auch bei wasserlosen Druckverfahren einsetzen.The proposed short inking unit can be used both in printing processes, in which a dampening solution is used, as well as in waterless printing process deploy.
Die Erfindung soll nachfolgend an Hand eines Ausführungsbeispieles beschrieben werden. Die dazugehörige Figur zeigt die schematische Darstellung des erfindungsgemäßen Kurzfarbwerkes.The Invention will be described below with reference to an embodiment to be discribed. The accompanying figure shows the schematic Representation of the short inking unit according to the invention.
