Abstract
Description
Die Erfindung betrifft ein Druckwerk einer Rotationsdruckmaschine zur Erzeugung von Irisdrucken.The The invention relates to a printing unit of a rotary printing press for the production from iris printing.
Die Herstellung von verlaufenden Farbtönen, dem so genannten Irisdruck, ist seit langem bekannt. Der Farbkasten wird hierfür durch Farbtrenner quer zur Druckrichtung in mehrere Segmente unterteilt. In jedem Bereich des Farbkastens kann eine andere Farbe gefüllt werden. Somit können in einem Druckwerk mehrere Farben nebeneinander auf dem Bedruckstoff gedruckt werden. Unter gezielter Nutzung der seitlichen Verreibung auf einer oder mehrerer nachfolgenden Farbübertragwalzen werden die Farben an ihren Grenzen zueinander miteinander vermischt, indem die Verreibewalzen axiale Bewegungen quer zur Rotationsrichtung der Walzen ausführen. Die so vermischte Farbe wird in konventioneller Weise über nachfolgende Farbübertragwalzen eines so genannten Langfarbwerkes und eine Druckform auf den Bedruckstoff aufgedruckt. Nachteilig daran ist, dass die Langfarbwerke eine Vielzahl von Walzen aufweisen. Durch die Vielzahl der Walzen soll eine gute Verteilung der Druckfarbe auf dem Plattenzylinder erreicht werden. Andererseits bedingen lange Farbwerke lange Einrichtzeiten und hohen Makulaturanfall. Dies führt gerade bei kleineren Auflagen zu hohen Kostenbelastungen.The Production of running shades, the so-called Iris printing has been known for a long time. The color box will do this divided by color separator transversely to the printing direction into several segments. In each area of the color box, another color can be filled become. Thus, in a printing unit several colors printed side by side on the substrate. Under targeted Use of lateral trituration on one or more subsequent ones Paint transfer rollers become the colors at their boundaries mixed together by the Verreibewalzen axial movements transverse to the direction of rotation of the rollers. The way mixed color is transferred in a conventional manner via subsequent Ink transfer rollers of a so-called long-inking unit and a printing form printed on the substrate. The disadvantage of this is the long inking units have a multiplicity of rollers. By The variety of rollers should have a good distribution of the printing ink can be achieved on the plate cylinder. On the other hand, require long inking long setup times and high waste of paper. this leads to especially for smaller runs at high cost burdens.

Dieses Verfahren erfordert eine Vielzahl von Druckwerken und ist damit sehr aufwändig.This Method requires a large number of printing units and is so very expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der auf vereinfachte Art und Weise ein Irisdruck erzeugt werden kannOf the Invention is therefore based on the object to a device create an iris print in a simplified way can be
Erfindungsgemäß wird die Aufgabe durch ein Druckwerk mit den Merkmalen des 1. Anspruchs gelöst.According to the invention the problem is solved by a printing unit having the features of the first claim.
Die Erfindung hat den Vorteil, dass mit einer geringen Anzahl von Farbwerkwalzen ein Farbverlaufsmuster erzeugt werden kann, bei der eine beliebigen Anzahl von unterschiedlichen Farben in einem einzigen Druckwerk gleichzeitig verwendet werden können. Das erfindungsgemäß vorgeschlagene Kurzfarbwerk für den Irisdruck weist keine Farbzonen auf, wodurch es einfach zu bedienen ist. Das Kurzfarbwerk wird in sehr kurzer Zeit gefüllt. Es eignet sich sowohl für den indirekten als auch für den direkten Druck. Es lässt sich einsetzen bei Druckverfahren, bei denen ein Feuchtmittel zum Einsatz kommt, und bei Druckverfahren, die wasserlos arbeiten.The Invention has the advantage that with a small number of inking rollers a gradient pattern can be generated in which any Number of different colors in a single printing unit can be used simultaneously. The inventively proposed short inking unit for the iris print has no color zones, which makes it easy to use. The short inking unit will be in a very short time filled. It is suitable for both the indirect as well as for direct printing. It can be used in printing processes where a dampening solution is used comes, and in printing processes that work waterless.
Im Folgenden soll die Erfindung beispielhaft erläutert werden. Die dazugehörigen Zeichnungen stellen dabei dar:in the The invention will be explained by way of example below. The accompanying drawings represent:
