Abstract

The system has a screen roller (03) and at least one form roller (04) to ink a form cylinder (06). The circumference of the form cylinder is an integer multiple of the circumference of the form roller. The form roller is assigned to a calender cylinder (05) to guide movement in the axial direction. The form roller and the calender cylinder have the same diameter.

Description

Kurzfarbwerk einer RotationsdruckmaschineShort inking unit of a rotary printing press
Die Erfindung betrifft ein Kurzfarbwerk einer Rotationsdruckmaschine gemäß dem Oberbegriff der Ansprüche 1 , 2, 3 oder 4.The invention relates to a short inking unit of a rotary printing press according to the preamble of claims 1, 2, 3 or 4.
Die WO 91/13761 A1 beschreibt ein Kurzfarbwerk einer Rotationsdruckmaschine, wobei Formzylinder und Farbauftragwalze gleichen Durchmesser aufweisen. Der Farbauftragwalze ist eine changierende Glättwalze zugeordnet.WO 91/13761 A1 describes a short inking unit of a rotary printing press, the forme cylinder and inking roller having the same diameter. An oscillating smoothing roller is assigned to the inking roller.
Der Erfindung liegt die Aufgabe zugrunde, ein Kurzfarbwerk einer Rotationsdruckmaschine zu schaffen.The invention has for its object to provide a short inking unit of a rotary printing press.
Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 , 2, 3 oder 4 gelöst.The object is achieved by the features of claims 1, 2, 3 or 4.
Dieses Kurzfarbwerk ohne Zonenschrauben ist vorzugsweise in Offsetdruckmaschinen für Qualitätsakzidenzdruck angeordnet.This short inking unit without zone screws is preferably arranged in offset printing machines for quality commercial printing.
Solche Farbwerke sind bekannt. Sie sind zweiwalzig mit Anilox- und Auftragwalze ausgebildet. Sie genügen für gute Zeitungsqualität. Bei Akzidenzqualität auf gestrichenen Papieren mit z. B. 70-iger Bildraster benötigt man Aniloxwalzen mit entsprechend feineren Gravuren als im Zeitungsdruck um Moiree-Erscheinungen zu vermeiden. Derartige Aniloxwalzen sind jedoch empfindlich gegen mechanische Beschädigungen.Such inking units are known. They have two rollers with anilox and applicator rollers. They are enough for good newspaper quality. For commercial quality on coated papers with e.g. B. 70 image grid requires anilox rollers with correspondingly finer engravings than in newspaper printing to avoid moiree phenomena. However, such anilox rollers are sensitive to mechanical damage.
Erfindungsgemäß ist eine gröbere, d. h. mechanisch stabilere Stuktur der Aniloxwalze dann auch für Feinraster einsetzbar, wenn der Farbfilm mit Grobraster auf der Auftragwalze geglättet ist bevor die Platte berührt wird. Glättwalzen mit seitlicher Verreibung sind bei klassischen Farbwerken an sich bekannt. Sie sind aber im Durchmesser klein gehalten, machen mehr als eine Umdrehungen pro Drucklänge und kehren mit ihren Umkehrpunkten bei der seitlichen Verreibung auf der Form um.According to the invention, a coarser, ie mechanically more stable, structure of the anilox roller can also be used for fine screens if the ink film with coarse screen is smoothed on the application roller before the plate is touched. Smoothing rollers with lateral rubbing are known per se in classic inking units. However, they are kept small in diameter, make more than one revolution per printing length and reverse with their reversal points when rubbing on the side of the mold.
Daher gibt es Schablonieren, Farbanreichungen insbesondere auch vom Druckkanal bei Bogendruckmaschinen und Farbabfall über die Umfangslänge zum Druckende.Therefore, there are stencils, color enhancements, especially from the printing channel in sheetfed printing machines, and ink waste over the circumferential length to the end of the print.
In neuartiger Weise wird vorgeschlagen, nur einen einzigen Glättzylinder zu verwenden, der 1:1 umlauft und deshalb nicht im Umfang Schablonieren kann.In a new way, it is proposed to use only a single smoothing cylinder, which rotates 1: 1 and therefore cannot stencil the extent.
Ein Einfallen in die Auftragwalzengrube wird durch Schmitzringe vermieden und ein Stehenbleiben in der Grube durch Zahnradantrieb. Bei endlos aufvulkanisierter 1:1 Auftragwalze können Schmitzringe und Zahnradantrieb entfallen. Höchste Eindruckqualität ist jedoch mit Offsetdrucktüchern als Farbübertragungsmedium auf dem Auftragwalzen-Zylinder zu erreichen, was einen Spannkanal bedingt oder eine aufvulkanisierte Gummizylinderhülse.Falling into the applicator roller pit is avoided by bearer rings and stopping in the pit by gear drive. With an endlessly vulcanized 1: 1 applicator roller, bearer rings and gear drive can be omitted. However, the highest impression quality can be achieved with offset printing blankets as the ink transfer medium on the applicator cylinder, which requires a tensioning channel or a vulcanized rubber cylinder sleeve.
Der Glättzylinder wird auf zwei Umdrehungen nur einmal hin- und herbewegt. Bei der ersten Umdrehung macht er über die gesamte Druckabwicklung einen Hinweg von ca. 15 bis 20 mm. Im Zylinderkanal der Auftragwalze erfolgt die Bewegungsumkehr. Bei der i zweiten Umdrehung läuft der Glättzylinder zurück - wiederum über die gesamte Druckabwicklungslänge ohne Bewegungsumkehr. Die Umkehr erfolgt wiederum in der Zylindergrube. Damit ist sichergestellt, daß keine Farbunterschiede durch Stillstehen oder Bewegungsumkehr des Glättzylinders auf der Auftragwalze, der Platte und damit im Druckbild auf Papier sichtbar werden.The smoothing cylinder is only reciprocated once in two revolutions. At the first turn, it makes a path of approx. 15 to 20 mm over the entire printing process. The movement is reversed in the cylinder channel of the applicator roller. With the second rotation, the smoothing cylinder runs back - again over the entire length of the print run without reversing the movement. The reverse takes place in the cylinder pit. This ensures that there are no color differences due to standstill or reversal of movement of the smoothing cylinder on the application roller, the plate and thus in the printed image on paper.
Der axiale Hub des Glättzylinders muß in jedem Fall so groß sein, daß im Berührungsstreifen zwischen Glättzylinder und Farbauftragwalze mehr als ein Näpfchen bzw. eine Haschur Abstand auf der Rasterwalze seitlich verrieben wird.The axial stroke of the smoothing cylinder must in any case be so large that there is more than one well in the contact strip between the smoothing cylinder and the inking roller or a hashing distance is rubbed laterally on the anilox roller.
Das Dreiwalzenfarbwerk - d. h. ein Zweiwalzenfarbwerk mit zusätzlicher 1:1 großer Glättwalze - zeigt schablonierfreie Einfärbung von extrem schwierigen Druckformen bei guten Farbdichten über die Breite und im Umfang.The three-roller inking unit - d. H. a two-roller inking unit with an additional 1: 1 large smoothing roller - shows stencil-free inking of extremely difficult printing forms with good ink densities across the width and circumference.
In weiterer Ausbildung der Erfindung kann die Farbauftragwalze z. B. mit einem doppeltgroßem Plattenzylinder für zwei verschiedene Farbplatten im Umfang und damit im Zylinderverhältnis 2:1 oder auch mehr zusammenarbeiten. Dann muß die Auftragwalze getaktet werden, um nur ihre Farbplatte einzufärben, während sie weiter mit der Aniloxwalze im Kontrakt bleibt. In diesem Fall muß Glättzylinder der geringfügigen Lageveränderung der Auftragwalze folgen, d. h. die Schmitzringberührung bleibt durch geeignete Maßnahmen erhalten.In a further embodiment of the invention, the inking roller z. B. with a double-sized plate cylinder for two different color plates in scope and thus in the cylinder ratio 2: 1 or more. Then the applicator roller must be clocked so that only its ink plate is inked while it remains in the contract with the anilox roller. In this case, the smoothing cylinder must follow the slight change in position of the application roller, i.e. H. The bearer ring contact is retained by suitable measures.
