Abstract
Description
Die Erfindung betrifft eine Rotationsdruckmaschine nach dem Oberbegriff von Patentanspruch 1. Als Rotationsdruckmaschinen eignen sind insbesondere Offsetdruckmaschinen und/oder Lackierwerke mit mindestens zwei Druck-/Lackwerken für die Verarbeitung von Bedruckstoffen.The invention relates to a rotary printing press according to the preamble of
In Rotationsdruckmaschinen wird die Oberfläche einer auf dem Formzylinder bzw. Plattenzylinder fixierten Druckform mittels mehreren Farbauftragwalzen eingefärbt und bei Bedarf im Nassoffsetdruck durch wenigstens eine Feuchtauftragwalze mit Feuchtmittel benetzt. Bei Lackierwerken wird die auf dem Formzylinder fixierte Druckform (eingeschlossen ein Gummituch) mittels wenigstens einer Lackauftragwalze mit Lack benetzt. Derartige Formzylinder weisen in der Regel einen Zylinderkanal für die Fixierung der Druckform mittels Spannmitteln auf. Beim Passieren des Zylinderkanals des Formzylinders kann von den Auftragwalzen (Farb-, Feucht-, Lackauftragwalzen) keine Farbe, Feuchtmittel bzw. Lack an die Druckform übertragen werden. Es kann sich somit ein etwa streifenförmiger Überschuss an Farbe, Feuchtmittel bzw. Lack an der jeweiligen Auftragwalze aufbauen und zur Überfärbung, Überfeuchtung bzw. Überlackierung eines nachfolgenden Teils der Druckform führen. Da das Bogenmaterial mittels zumindest einen Zylinderkanal aufweisende Bogenführungszylinder (Druckzylinder, Transferzylinder) in Förderrichtung durch die Bogenrotationsdruckmaschine gefördert wird, können beim Durchlaufen des Bogenmaterials durch mehrere Druck-/Lackierwerke sich diese Effekte überlagern und somit die Druck-/Lackierqualität beinträchtigen, indem sich Streifen auf dem Drucksujet des Bogenmaterials abbilden.In rotary printing machines, the surface of a fixed on the forme cylinder or plate cylinder printing plate is colored by means of several inking rollers and wetted if necessary in wet offset by at least one dampening roller with fountain solution. In coating plants, the printing forme fixed on the forme cylinder (including a rubber blanket) is wetted with lacquer by means of at least one lacquer applicator roller. Such form cylinder usually have a cylinder channel for the fixation of the printing plate by means of clamping means. When passing through the cylinder channel of the forme cylinder, no ink, dampening solution or paint can be transferred to the printing form from the applicator rollers (ink, damp, lacquer application rollers). It may thus build up an approximately strip-shaped excess of color, dampening solution or paint on the respective applicator roller and lead to over-staining, over-moistening or repainting of a subsequent part of the printing form. Since the sheet material by means of at least one cylinder channel having sheet guiding cylinder (printing cylinder, transfer cylinder) is conveyed in the conveying direction by the sheet-fed rotary printing machine, these effects can overlap as the sheet material passes through several printing / varnishing and thus affect the printing / Lackierqualität by stripes on Imagine the print subject of the sheet material.

Bei derartigen Rotationsdruckmaschinen ist bekanntlich die geometrische Anordnung von Zylinderkanal, Druckanfang, Druckende der Formzylinder, Gummituchzylinder sowie Druckzylinder von Druck-/Lackwerk zu Druck-/Lackwerk gleich.In such rotary printing machines, as is well known, the geometric arrangement of the cylinder channel, the beginning of the printing, the end of the printing of the forme cylinder, the blanket cylinder and the impression cylinder from the printing / coating unit to the printing / coating unit are the same.
Aufgabe der Erfindung ist es, eine Rotationsdruckmaschine der eingangs genannten Art zu schaffen, die insbesondere die durch das Passieren eines Zylinderkanals eines Formzylinders bedingten Beeinträchtigungen der Druckqualität kompensiert.The object of the invention is a rotary printing machine of the aforementioned To create a type that compensates in particular the caused by the passage of a cylinder channel of a forme cylinder impairments in print quality.

Ein erster Vorteil der Erfindung ist darin begründet, dass im Druck-/Lackierbetrieb ein gleichmäßigerer Walzenstreifen auf dem Drucksujet erzeugt wird, indem zumindest ein Formzylinder eines Druck-/Lackwerkes eine spezielle Zylinderkanalanordnung aufweist. Durch diese spezielle Zylinderkanalanordnung verändert sich auch der Druck-/Lackanfang sowie das Druck-/Lackende an diesem Formzylinder. In Weiterbildungen kann die Erfindung ebenso bei den Zylinderkanälen der Gummituchzylinder und/oder der Bedruckstoff führenden Druckzylindern realisiert sein.A first advantage of the invention is due to the fact that a more uniform roll strip is produced on the print substrate in the printing / coating operation, in that at least one forme cylinder of a printing / coating unit has a special cylinder channel arrangement. This special cylinder channel arrangement also changes the beginning of the print / varnish and the end of the print / varnish on this forme cylinder. In further developments, the invention can also be realized in the cylinder channels of the blanket cylinder and / or the printing material leading printing cylinders.
Ein zweiter Vorteil besteht darin, dass durch die spezielle Zylinderkanalanordnung der beim Walzenanlauf an einer Kanalkante initiierte Stoß (Kanalschlag) der jeweiligen Auftragwalze (von Farbwerk und bei Bedarf Feuchtwerk) kompensiert und die drucktechnischen Störungen, insbesondere Schwingungen, in dem Druck-/Lackwerk bzw. der Rotationsdruckmaschine reduziert. Weiterhin wird das Auftreten von sichtbaren Streifen im Drucksujet vermieden und somit die Druckqualität verbessert.A second advantage is that compensated by the special cylinder channel arrangement initiated at the roll start on a channel edge shock (channel impact) of the respective applicator roll (inking unit and if necessary dampening unit) and the printing technology disturbances, in particular vibrations in the printing / coating unit or the rotary printing machine reduced. Furthermore, the occurrence of visible streaks in the printed matter is avoided, thus improving the print quality.
