Description

Die Erfindung betrifft ein Druckwerk einer Druckmaschine ohne Feuchtwerk gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a printing unit of a printing press without dampening unit according to the preamble of claim 1.

Manche Druckwerke arbeiten ohne Feuchtmittel und sind auf diese Weise insbesondere für den wasserlosen Rollenoffsetdruck geeignet. Beim Drucken ohne Feuchtmittel wird auf den Plattenzylinder des Druckwerks eine Druckplatte befestigt, die die Übertragung des Druckbildes auch ohne Feuchtmittel erlaubt. Dazu weist die Druckplatte eine untere Schicht aus einem farbannehmenden Material und eine obere Schicht aus einem farbabstoßendem Material auf. Die Farbabstoßung an der oberen Schicht erfolgt dabei ohne Feuchtmittel. Dementsprechend sind zur Herstellung der oberen Schicht besondere Materialien erforderlich. Insbesondere haben sich silikonhaltige Materialien zur feuchtmittellosen Farbabstoßung als geeignet erwiesen.Some printing units work without dampening solution and are thus particularly suitable for waterless web offset printing. When printing without dampening solution is attached to the plate cylinder of the printing unit, a printing plate, which allows the transfer of the printed image without dampening solution. For this purpose, the printing plate on a lower layer of a ink-accepting material and an upper layer of a ink-repellent material. The ink repellency on the upper layer is carried out without dampening solution. Accordingly, special materials are required to make the top layer. In particular, silicone-containing materials have proven suitable for damp-proof ink repellency.

Die obere und damit farbabstoßende Schicht der Druckplatte weist an den zu druckenden Bereichen des Druckbildes Durchbrechungen auf, so dass sich die Druckfarbe an der darunterliegenden farbannehmenden Schicht anlagern kann. Auf diese Weise kann das Druckbild bei gattungsgemäßen Druckwerken auf einen nachgeordneten Übertragungszylinder, beispielsweise einen Gummituchzylinder, übertragen werden. An den nicht zu druckenden Bereichen des Druckbildes überdeckt die obere Schicht die untere Schicht, so dass in diesen Bereichen keine Druckfarbe übertragen wird.The upper and thus ink-repellent layer of the printing plate has openings on the areas of the printed image to be printed, so that the printing ink can accumulate on the underlying ink-accepting layer. In this way, the printed image in generic printing on a downstream transfer cylinder, such as a blanket cylinder, are transmitted. At the areas of the printed image which are not to be printed, the upper layer covers the lower layer so that no ink is transferred in these areas.

Ein Druckwerk für den wasserlosen Offsetdruck ist beispielsweise in der WO 03/045695 A1 beschrieben.A printing unit for waterless offset printing is for example in the WO 03/045695 A1 described.

Die EP 0 182 156 B1 zeigt einen Gummizylinder mit einem im Radius reduzierten Bereich.The EP 0 182 156 B1 shows a rubber cylinder with a radius reduced Area.

Durch die DE 44 00 020 A1 ist ein Gummituch bekannt dessen Enden verjüngt sind.By the DE 44 00 020 A1 is a blanket known whose ends are tapered.

Die DE 198 02 470 A1 offenbart ein mehrschichtiges Gummituch.The DE 198 02 470 A1 discloses a multilayer blanket.

Die DE 33 15 506 A1 beschreibt ein Offsettuch, welches zwischen seinen Enden eine in axialer Richtung verlaufende Aussparung aufweist, um ein Mitdrucken der Plattenkanten zu vermeiden.The DE 33 15 506 A1 describes an offset blanket, which has between its ends a recess extending in the axial direction in order to avoid Mitdrucken the plate edges.

Werden am Plattenzylinder mehrere Druckplatten in Umfangsrichtung hintereinander mit zueinanderweisenden Enden befestigt, so ergibt sich beim gattungsgemäßen Flachdruck ohne Feuchtmittel das Problem, dass die Enden der Druckplatten oftmals zumindest schwach mitgedruckt werden, obwohl die Enden in einem an sich nicht zu druckenden Bereich des Druckbildes liegen.If a plurality of printing plates in the circumferential direction one behind the other with fastened ends attached to the plate cylinder, the result is the generic flat printing without dampening solution the problem that the ends of the printing plates are often at least weak mitgesruckt, although the ends are in a not to be printed on itself area of the printed image.

Der Erfindung liegt die Aufgabe zugrunde, ein Druckwerk einer Druckmaschine ohne Feuchtwerk zu schaffen, bei dem die Enden der Druckplatten auch beim Flachdruck ohne Feuchtmittel nicht mitdrucken.The invention has for its object to provide a printing unit of a printing press without dampening, in which the ends of the printing plates not mitdrucken even in planographic without dampening solution.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Ein Vorteil des Druckwerks liegt insbesondere darin, dass den Enden der Druckplatten Vertiefungen auf der Mantelfläche des Übertragungszylinders gegenüberliegen, die sich parallel zur Längsachse des Übertragungszylinders erstrecken. Auf diese Weise wird ein Farbübertrag von den Enden der Druckplatten auf den Übertragungszylinder verhindert. Im Ergebnis werden so die Enden der Druckplatten auch beim Flachdruck ohne Feuchtmittel nicht mitgedruckt, da ein Farbübertrag dieses Bereichs aufgrund der Vertiefungen auf dem Übertragungszylinder ausgeschlossen ist.An advantage of the printing unit is in particular that the ends of the printing plates opposite recesses on the lateral surface of the transfer cylinder, which extend parallel to the longitudinal axis of the transfer cylinder. In this way, a transfer of ink from the ends of the printing plates is prevented on the transfer cylinder. As a result, the ends of the printing plates are not printed in the planographic printing without fountain solution, as a color transfer of this area is excluded due to the wells on the transfer cylinder.

In welcher Weise der Übertragungszylinder konstruktiv ausgebildet ist, ist grundsätzlich beliebig. Nach einer bevorzugten Ausführungsform weist der Übertragungszylinder ein Drucktuch mit einer formstabilen Trägerplatte und einer auf der Trägerplatte befestigten Beschichtung auf. Zur Befestigung des Drucktuchs können die Enden der Trägerplatte am Übertragungszylinder festgelegt werden. Die Mantelfläche des Übertragungszylinders wird von der Außenseite der Beschichtung gebildet.In what way the transfer cylinder is designed constructively, is basically arbitrary. According to a preferred embodiment, the transfer cylinder on a blanket with a dimensionally stable support plate and a fixed to the support plate coating. For attachment of the blanket, the ends of the carrier plate can be fixed to the transfer cylinder. The lateral surface of the transfer cylinder is formed by the outside of the coating.

Eine Vertiefung am Übertragungszylinder kann durch den Abstand zwischen dem vorlaufenden Ende und dem nachlaufenden Ende des Drucktuchs, insbesondere durch den Abstand zwischen der vorlaufenden Seitenkante und der nachlaufenden Seitenkante der Beschichtung des Drucktuchs, gebildet werden.A recess on the transfer cylinder can be formed by the distance between the leading end and the trailing end of the blanket, in particular by the distance between the leading side edge and the trailing side edge of the coating of the blanket.

Additiv dazu kann die Beschichtung zwischen dem vorlaufenden Ende und dem nachlaufenden Ende des Drucktuchs, insbesondere zwischen der vorlaufenden Seitenkante und der nachlaufenden Seitenkante der Beschichtung des Drucktuchs, insbesondere ungefähr mittig zwischen diesen beiden Seitenkanten, eine in die Beschichtung des Drucktuchs eingearbeitete Nut aufweisen. Die Tiefe der Nut sollte dabei vorzugsweise ungefähr 5 % bis 15 % der Dicke der Beschichtung entsprechen.Additively, the coating between the leading end and the trailing end of the blanket, in particular between the leading side edge and the trailing side edge of the coating of the blanket, in particular approximately midway between these two side edges, have a groove incorporated into the coating of the blanket. The depth of the groove should preferably correspond to approximately 5% to 15% of the thickness of the coating.

Alternativ zur Verwendung eines Drucktuchs mit Trägerplatte sind auch Drucktücher denkbar, deren Enden selbst am Übertragungszylinder festgelegt werden. Bei derartigen Drucktüchern kann eine Vertiefung durch den Abstand zwischen der vorlaufenden und der nachlaufenden Einhängekante des Drucktuchs gebildet sein. Weiter ist es auch möglich zur Bildung der Vertiefung eine Nut in das Drucktuch einzuarbeiten. Ist zwischen dem Drucktuch und dem Übertragungszylinder ein Unterzug vorgesehen, so kann der Unterzug zur Bildung der Vertiefung am Außenumfang des Drucktuchs zumindest eine Unterbrechung oder eine Querschnittsverringerung aufweisen.Alternatively to the use of a blanket with carrier plate and blankets are conceivable, the ends are set even on the transfer cylinder. In such blankets, a recess may be formed by the distance between the leading and the trailing hemming edge of the blanket. Further, it is also possible to form a groove in the blanket to form the depression. If a joist is provided between the blanket and the transfer cylinder, the joist for forming the depression on the outer circumference of the blanket may have at least one interruption or reduction in cross-section.

Die Breite der Vertiefung in Umfangsrichtung sollte ungefähr 0,1 % bis 1 % der Länge des Drucktuchs in Umfangsrichtung entsprechen.The width of the groove in the circumferential direction should be about 0.1% to 1% of the length of the Compressed blanket in the circumferential direction.

Besonders vorteilhaft ist es, wenn der Plattenzylinder und/oder der Übertragungszylinder temperiert werden kann, da durch die Temperierung der Farbübertragungsprozess der feuchtmittellosen Druckfarbe besser geführt werden kann. Nachfolgend wird die Erfindung anhand der in den Zeichnungen dargestellten Ausführungsformen beispielhaft erläutert.It is particularly advantageous if the plate cylinder and / or the transfer cylinder can be tempered, since the ink transfer process of the inkless ink can be better guided by the temperature control. The invention will be explained by way of example with reference to the embodiments shown in the drawings.

Process steps for producing a printing blanket unit.

In Fig. 1 ist ein Teil eines Druckwerks 01 mit einem Plattenzylinder 02 und einem daran anliegenden Übertragungszylinder 03 in perspektivischer Ansicht dargestellt. Am Umfang des Plattenzylinders 02 sind in vier Reihen nebeneinander jeweils zwei Druckplatten 04, insbesondere Flachdruckplatten 04, in Umfangsrichtung hintereinander befestigt, so dass sich eine Gesamtzahl von insgesamt acht Druckplatten 04 am Plattenzylinder 02 ergibt. Die Druckplatten 04 übertragen das gewünschte Druckbild im feuchtmittellosen Flachdruck auf die Umfangsfläche des Übertragungszylinders 03, von wo es beispielsweise auf eine Bedruckstoffbahn im Offsetdruck übertragen wird.In Fig. 1 is a part of a printing unit 01 with a plate cylinder 02 and an adjacent transfer cylinder 03 shown in a perspective view. On the circumference of the plate cylinder 02 are in four rows next to each other two printing plates 04, in particular planographic printing plates 04, mounted one behind the other in the circumferential direction, so that a total of eight printing plates 04 on the plate cylinder 02 results. The printing plates 04 transfer the desired print image in damp-proof flat printing onto the circumferential surface of the transfer cylinder 03, from where it is transferred, for example, to a printing material web in offset printing.

Die Herstellung der die Druckfarbe übertragenden Umfangsschicht an den Druckplatten 04 soll nachfolgend anhand der fünf Skizzen in Fig. 2, die die einzelnen Schritte zur Herstellung einer feuchtmittellosen arbeitenden Druckplatte 04 beispielhaft darstellen, kurz erläutert werden.The preparation of the ink transferring peripheral layer on the printing plates 04 will be described below with reference to the five sketches in Fig. 2 , which illustrate the individual steps for producing a dampening-free working pressure plate 04 by way of example, will be explained briefly.

Wie aus Fig. 2a zu erkennen ist, ist die Druckplatte 04 aus einer Trägerschicht 06, beispielsweise aus Aluminium, einer Farbübertragungsschicht 07 aus einem farbübertragenden Material, einer farbabstoßenden Schicht 08 aus einem farbabstoßenden Material, z. B. Silikon, und einer Schutzschicht 09 aufgebaut.Zur Übertragung des gewünschten Druckbildes auf die Druckplatte 04 wird diese beispielsweise unter Verwendung eines das Druckbild enthaltenen Positivfilms 11 belichtet (Fig. 2b). Zur Belichtung kann insbesondere UV-Licht eingesetzt werden. An den belichteten Stellen der Druckplatte 04 löst sich die farbabstoßende Schicht 08 lokal begrenzt ab (Fig. 2c) und kann mit geeigneten Lösungsmitteln bereichsweise abgewaschen werden. Im Ergebnis deckt dann die farbabstoßende Schicht 08 die farbübertragende Schicht 07 an den Stellen des Druckbildes ab, die später nicht gedruckt werden sollen (Fig.2d). An den zu druckenden Stellen des Druckbildes enthält die farbabstoßende Schicht 08 Durchbrechungen 12. Während des Druckprozesses kann sich die Druckfarbe 13 im Bereich der Durchbrechungen 12 an der farbübertragenden Schicht 07 anlagern und somit auf den nachgeordneten Übertragungszylinder 03 übertragen werden (Fig. 2e). Im Ergebnis ist damit eine feuchtmittellose Übertragung der Druckfarbe 13 möglich. Zur Herstellung feuchtmittellos arbeitender Druckplatten sind selbstverständlich auch andere Herstellungsverfahren bekannt und einsetzbar.How out Fig. 2a can be seen, the pressure plate 04 from a support layer 06, for example, aluminum, a color transfer layer 07 of a color-transferring material, an ink-repellent layer 08 of an ink-repellent material, eg. B. silicone, and a protective layer 09.Zur transfer of the desired print image on the printing plate 04, this example, using a positive film 11 containing the printed image illuminated ( Fig. 2b ). For exposure, in particular UV light can be used. At the exposed areas of the printing plate 04, the ink-repellent layer 08 is detached locally ( Fig. 2c ) and can be washed off in areas with suitable solvents. As a result, the ink-repellent layer 08 then covers the ink-transferring layer 07 at the locations of the printed image which are not to be printed later ( Figure 2d ). During the printing process, the printing ink 13 can accumulate in the region of the perforations 12 on the ink-transferring layer 07 and thus be transferred to the downstream transfer cylinder 03 (in the case of the printing process). Fig. 2e ). As a result, a damp-free transfer of the printing ink 13 is possible. Of course, other manufacturing processes are also known and can be used to produce printing plates that operate without dampening agents.
