Abstract

The printing machine has two interacting blanket cylinders (1,2) which are each inked by several offset plate cylinders (5,12) and between which the paper (P) to be printed on both sides runs through. One of the blanket cylinders (2) is also in contact with a plate cylinder (8) carrying a collect printing plate which is inked in a multicolor manner by a further blanket cylinder (9). This blanket cylinder (9) receives the inks from several appropriately inked selective color inking cylinders (10). Also arranged between the two blanket cylinders (2,9), which are in contact with the plate cylinder (8) carrying the collect printing plate, is an adjustable and convertible plate cylinder (16) which, in a first working position, carries an offset plate and rests against the blanket cylinder (2) inked by the offset plate cylinders (12), whilst in a second working position it carries a selective color inking plate and rests against the blanket cylinder (9) inked by the selective color inking cylinders (10). Thus, it is possible to produce on one side of the paper a multicolor pattern which is made by means of two different printing processes and in which either the number of colors used in collect printing or the number of colors used in offset printing is selectively increased by one color.

Description

Die Erfindung bezieht sich auf eine Mehrfarbenrotationsdruckmaschine zum gleichzeitigen Schön- und Widerdruck, insbesondere zum Druck des Sicherheitsuntergrundes auf Banknoten, gemäss dem Oberbegriff des Patentanspruchs 1 sowie auf ein Verfahren zum Betrieb dieser Druckmaschine.The invention relates to a multi-color rotary printing machine for simultaneous face and reverse printing, in particular for printing the security background on banknotes, according to the preamble of claim 1 and to a method for operating this printing machine.

Eine derartige Druckmaschine ist aus der europäischen Patentanmeldung mit der Veröffentlichungsnummer 0133328 bekannt und erlaubt es, in einer einzigen Druckoperation gleichzeitig zwei vollkommen verschiedene Druckverfahren anzuwenden, indem auf der einen Papierseite ein Mehrfarbenbild nach dem Offsetdruckverfahren und gleichzeitig auf der anderen Papierseite ein Mehrfarbenbild nach dem Sammeldruckverfahren, auch "Orlof"-Verfahren genannt, gedruckt wird. Während das Offsetbild aus Überlagerten Farben besteht, weist das nach dem Sammeldruckverfahren hergestellte Bild nebeneinanderliegende Farben auf. Diese Druckmaschine ist besonders für den Banknotendruck geeignet, da sie in einem einzigen Durchgang beide Banknotenseiten mit einem nach verschiedenen Verfahren erhaltenen mehrfarbigen Sicherheitsuntergrund zu bedrucken erlaubt, was die Sicherheit gegen Fälschung erhöht.Such a printing press is known from the European patent application with the publication number 0133328 and allows two completely different printing methods to be used simultaneously in a single printing operation, by a multicolor image using the offset printing method on one paper side and a multicolor image using the batch printing method simultaneously on the other paper side, also known as the "Orlof" process. While the offset image consists of superimposed colors, the image produced using the batch printing process has adjacent colors. This printing machine is particularly suitable for banknote printing, since it allows both sides of the banknote to be printed in a single pass with a multicolored security background obtained by various methods, which increases security against counterfeiting.

Der Erfindung liegt die Aufgabe zugrunde, bei einer derartigen Druckmaschine verschiedene Kombinationsmöglichkeiten für den Druck von Mehrfarbenbildern zu schaffen.The invention has for its object to provide various possible combinations for printing multicolor images in such a printing press.

Diese Aufgabe wird erfindungsgemäss durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Das Verfahren zum Betrieb dieser Druckmaschine ist im Patentanspruch 3 angegeben. Der Vorteil dieser Druckmaschine besteht darin, dass einerseits mittels des verstellbaren und konvertiblen Plattenzylinders wahlweise entweder die Anzahl der beim Sammeldruck oder die Anzahl der beim Offsetdruck verwendeten Farben um eine Farbe erhöht werden kann und andererseits die nach dem Sammeldruckverfahren bedruckte Papierseite zusätzlich mehrere Offsetdrucke erhält. Dadurch wird einerseits die Wirtschaftlichkeit der Druckmaschine erhöht, da sie nach Wunsch verschiedenartige Druckkombinationen ermöglicht, und andererseits wird beim Banknotendruck eine sehr hohe Sicherheit gegen Fälschung erzielt, da das Mehrfarbenbild auf ein und derselben Banknotenseite nach zwei verschiedenen Druckverfahren hergestellt wird.According to the invention, this object is achieved by the features specified in patent claim 1. The method for operating this printing machine is specified in claim 3. The advantage of this printing press is that on the one hand, using the adjustable and convertible plate cylinder, either the number of colors used in batch printing or the number of colors used in offset printing can be increased by one color, and on the other hand, the paper page printed using the batch printing process can also receive several offset prints. On the one hand, this increases the profitability of the printing press, since it enables different printing combinations, and on the other hand, a very high level of security against counterfeiting is achieved in banknote printing, since the multicolor image is produced on one and the same banknote side using two different printing processes.

Eine zweckmässige Anordnung der drei Gummizylinder der Maschine, bei der es sich vorzugsweise um eine Rollendruckmaschine handeln kann, ergibt sich aus dem Patentanspruch 2.An expedient arrangement of the three rubber cylinders of the machine, which can preferably be a web-fed printing machine, results from patent claim 2.

Die Erfindung wird anhand der einzigen Figur an einem schematisch dargestellten Ausführungsbeispiel einer Rollendruckmaschine näher erläutert.The invention is explained in more detail with reference to the single figure in a schematically illustrated embodiment of a web printing press.

Diese Rollendruckmaschine weist zwei im Hauptgestell der Maschine horizontal nebeneinander gelagerte Gummizylinder 1 und 2 auf, die gegeneinander gepresst sind und den Druckspalt für die beidseitig zu bedruckende Papierbahn P bilden. Diese zwischen den Gummizylindern 1 und 2 hindurchlaufende Papierbahn P bewegt sich im betrachteten Beispiel im Sinne des Pfeils vertikal aufwärts, wird durch Führungs- und Spannrollen 3 geführt und gespannt und durchläuft nach der Bedruckung eine auf beide Papierseiten wirkende Trocknungsvorrichtung 4.This web printing machine has two rubber cylinders 1 and 2, which are horizontally juxtaposed in the main frame of the machine and are pressed against one another and form the printing nip for the paper web P to be printed on both sides. This paper web P passing between the rubber cylinders 1 and 2 moves vertically upward in the example under consideration in the direction of the arrow, is guided and tensioned by guide and tensioning rollers 3 and, after printing, passes through a drying device 4 acting on both paper sides.

Am Gummizylinder 1 liegen vier Offsetplattenzylinder 5 an, die von je einem Farbwerk 6 mit unterschiedlichen Farben eingefärbt werden. Im betrachteten Beispiel tragen die drei oberen Plattenzylinder 5 Trockenoffsetplatten, das heisst Hochdruckplatten, während der untere Plattenzylinder 5, der den Gummizylinder 1 bei jeder Umdrehung desselben zuletzt einfärbt, eine Feuchtoffsetplatte trägt, welche durch ein Feuchtwerk 7 angefeuchtet wird. Bei dieser Feuchtoffsetplatte handelt es sich vorzugsweise um eine Tiefdruckplatte.There are four offset plate cylinders 5 on the rubber cylinder 1, each of which is inked with different colors by an inking unit 6. In the example considered, the three upper plate cylinders 5 carry dry offset plates, that is to say high-pressure plates, while the lower plate cylinder 5, which lastly colors the rubber cylinder 1 with each revolution of the plate, carries a wet offset plate which is moistened by a dampening unit 7. This wet offset plate is preferably an intaglio printing plate.

Am Gummizylinder 2 liegt ein Plattenzylinder 8 an, der eine Sammeldruckplatte trägt. Hierbei handelt es sich um eine Hochdruckplatte, die ein in mehreren Farben einzufärbendes Muster oder Bild trägt. Ein weiterer, im Hauptgestell gelagerter Gummizylinder 9 befindet sich seinerseits mit dem Plattenzylinder 8 in Berührung und arbeitet mit drei Farbselektionszylindern 10 zusammen, welche Farbselektionsplatten, auch Farbkonturplatten genannt, tragen. Diese Farbselektionsplatten haben ausgeschnittene Reliefs mit Konturen, welche den mit einer bestimmten Farbe einzufärbenden Bereichen der Sammeldruckplatte des Plattenzylinders 8 entsprechen, und werden ihrerseits durch je ein Farbwerk 11 mit der betreffenden Farbe eingefärbt. Die Farbselektionszylinder 10 werden auch Schablonenwalzen genannt. Der als Farbsammelzylinder fungierende Gummizylinder 9 sammelt die einzelnen, von den Farbselektionszylindern 10 herrührenden Farben und überträgt sie auf die Sammeldruckplatte des Plattenzylinders 8. Vom so eingefärbten Plattenzylinder 8 wird das Mehrfarbenbild auf den Gummizylinder 2 und von diesem auf die eine Papierseite übertragen.A plate cylinder 8 bears on the blanket cylinder 2 and carries a collective printing plate. This is a high-pressure plate that bears a pattern or picture to be colored in several colors. Another rubber cylinder 9 mounted in the main frame is in turn in contact with the plate cylinder 8 and works with three color selection cylinders 10, which carry color selection plates, also called color contour plates. These color selection plates have cut-out reliefs with contours which correspond to the areas of the collective printing plate of the plate cylinder 8 which are to be colored with a specific color, and are in turn colored by the respective inking unit 11. The color selection cylinders 10 are also called stencil rollers. The rubber cylinder 9, which functions as a color collecting cylinder, collects the individual colors originating from the color selection cylinders 10 and transfers them to the printing plate of the plate cylinder 8. The multicolored image is transferred from the plate cylinder 8 thus inked to the rubber cylinder 2 and from there onto one side of the paper.

Das Verfahren, nach dem die vorstehend beschriebene Anordnung arbeitet, wird im allgemeinen Farbsammeldruck- oder auch "Orlof"-Verfahren genannt und liefert ein Mehrfarbenbild, bei welchem die einzelnen Farben nebeneinanderliegen und ein vollkommenes Register zwischen den verschiedenen Farben des Bildmusters garantiert ist. Da sich die Farbselektionsplatten mit der elastischen Oberfläche des Gummizylinders 9 in Kontakt befinden, können sie aus einem harten Material hergestellt werden, was das Ausschneiden sehr feiner Reliefzonen und damit sehr feiner Farbbereiche, beispielsweise in Form von Linien oder Punkten, erlaubt.The method according to which the arrangement described above works is generally called color batch printing or "Orlof" method and provides a multicolor image in which the individual colors lie side by side and a perfect register between the different colors of the image pattern is guaranteed. Since the color selection plates are in contact with the elastic surface of the rubber cylinder 9, they can be made of a hard material, which allows the cutting out of very fine relief zones and thus very fine color areas, for example in the form of lines or dots.

Der Gummizylinder 9 liegt im betrachteten Beispiel näherungsweise senkrecht oberhalb des Gummizylinders 2 und ist seitlich nur derart versetzt, dass er die vertikal aufwärts verlaufende Papierbahn P nicht berührt. Die Anordnung der drei Gummizylinder 1, 2 und 9 hat den Vorteil, dass diese einerseits leicht zugänglich sind und dass andererseits längs des Umfangs des Gummizylinders 2 viel freier Raum zur Anordnung von weiteren, diesen Gummizylinder 2 einfärbenden Plattenzylindern besteht. Im betrachteten Beispiel sind drei Offsetplattenzylinder 12 vorgesehen, die durch je ein Farbwerk 13 eingefärbt werden und von denen die beiden oberen Plattenzylinder 12 Trockenoffsetplatten tragen, während der untere Plattenzylinder 12 wiederum eine Feuchtoffsetplatte, vorzugsweise eine Tiefdruckplatte, trägt, die durch ein Feuchtwerk 14 angefeuchtet wird.In the example considered, the rubber cylinder 9 lies approximately vertically above the rubber cylinder 2 and is only laterally offset in such a way that it does not touch the paper web P running vertically upwards. The arrangement of the three rubber cylinders 1, 2 and 9 has the advantage that these are easily accessible on the one hand and that on the other hand there is a lot of free space along the circumference of the rubber cylinder 2 for the arrangement of further plate cylinders coloring this rubber cylinder 2. In the example considered, three offset plate cylinders 12 are provided, each of which is inked by an inking unit 13 and of which the two upper plate cylinders 12 carry dry offset plates, while the lower plate cylinder 12 in turn carries a wet offset plate, preferably an intaglio printing plate, which is moistened by a dampening unit 14 .

Zwischen den beiden Gummizylindern 2 und 9, im Abstand vom Plattenzylinder 8, ist ein weiterer Plattenzylinder 16 angeordnet, welcher konvertibei und derart verstellbar im Hauptgestell gelagert ist, dass er in einer ersten Arbeitsstellung am Gummizylinder 2 anliegt, wie in der Figur mit ausgezogener Linie dargestellt, und in einer zweiten Arbeitsstellung am Gummizylinder 9 anliegt, wie strichpunktiert dargestellt. Im ersten Falle, wenn der Plattenzylinder 16 mit dem Gummizylinder 2 zusammenarbeitet, trägt er eine Offsetplatte, und im zweiten Falle, wenn er mit dem Gummizylinder 9 zusammenarbeitet, trägt er eine Farbselektionsplatte. In beiden Fällen wird er von dem ihm zugeordneten Farbwerk 15 mit einer bestimmten Farbe eingefärbt.Between the two rubber cylinders 2 and 9, at a distance from the plate cylinder 8, a further plate cylinder 16 is arranged, which is mounted in the main frame in a convertible and adjustable manner such that it rests on the rubber cylinder 2 in a first working position, as shown in the figure with a solid line , and in a second working position on the blanket cylinder 9, as shown in broken lines. In the first case, when the plate cylinder 16 works together with the rubber cylinder 2, it carries an offset plate, and in the second case, when it works together with the rubber cylinder 9, it carries a color selection plate. In both cases, it is colored with a specific color by the inking unit 15 assigned to it.

Alle Plattenzylinder sind, wie die drei Gummizylinder 1, 2 und 9, im Hauptgestell der Maschine gelagert, während die den Plattenzylindern 5 zugeordneten Farbwerke 6 und das Feuchtwerk 7 auf der einen Seite in einem abfahrbaren Farbwerkgestell 18 und alle anderen Farbwerke 11, 13 und 15 und das Feuchtwerk 14 auf der anderen Seite in einem abfahrbaren Farbwerkgestell 17 installiert sind.All plate cylinders, like the three rubber cylinders 1, 2 and 9, are mounted in the main frame of the machine, while the inking units 6 assigned to the plate cylinders 5 and the dampening unit 7 on one side in a removable inking unit frame 18 and all other inking units 11, 13 and 15 and the dampening unit 14 are installed on the other side in a removable inking unit frame 17.

Im betrachteten Beispiel wird mittels des Gummizylinders 1 auf die eine Papierseite ein Vierfarben-Offsetdruck und mittels des Gummizylinders 2 auf der anderen Papierseite gleichzeitig ein Siebenfarben-Druck aufgebracht, bei dem es sich um einen kombinierten Sammeldruck-Offsetdruck handelt. Wenn der Plattenzylinder 16 eine Offsetdruckplatte trägt und am Gummizylinder 2 anliegt, handelt es sich um die Kombination eines Dreifarben-Sammeldrucks und eines Vierfarben-Offsetdrucks; im andern Falle, wenn der Plattenzylinder 16 eine Farbselektionsplatte trägt und am Gummizylinder 9 anliegt, entsteht die Kombination eines Vierfarben-Sammeldrucks und eines Dreifarben-Offsetdrucks. Der verstellbare und konvertible Plattenzylinder 16 erlaubt also sehr interessante Kombinationsdruckmöglichkeiten, wie sie insbesondere beim Banknotendruck wichtig sind.In the example under consideration, a four-color offset print is applied by means of the rubber cylinder 1 on one side of the paper and a seven-color print is simultaneously applied by means of the rubber cylinder 2 on the other side of the paper, which is a combined collective printing offset print. If the plate cylinder 16 carries an offset printing plate and lies against the blanket cylinder 2, it is a combination of a three-color collective printing and a four-color offset printing; otherwise, when the plate cylinder 16 carries a color selection plate and is in contact with the blanket cylinder 9, the combination of a four-color collective print and a three-color offset print is produced. The adjustable and convertible plate cylinder 16 thus allows very interesting combination printing options, as are particularly important in banknote printing.

im Falle eines Banknotendrucks lässt sich insbesondere auf der einen Seite ein vierfarbiger und auf der anderen Seite ein siebenfarbiger Sicherheitsuntergund herstellen, der aufgrund des nach zwei vollkommen verschiedenen Druckverfahren hergestellten Siebenfarbenbildes besonders sicher gegen Fälschung ist. Andererseits können die erwähnten Tiefdruckplatten, die sich auf dem untersten Plattenzylinder 5 und dem untersten Plattenzylinder 12 befinden, dazu verwendet werden, auf jeder Papierseite ein einfarbiges Hauptmuster zu drucken, während alle übrigen Plattenzylinder gleichzeitig einen mehrfarbigen Sicherheitsuntergrund liefern. In diesem Falle lässt sich also mit der beschriebenen Druckmaschine ein vollständiger beidseitiger Banknotendruck durchführen, wie er insbesondere für Banknoten geringerer Werte geeignet ist, bei denen im allgemeinen das Hauptmuster einfarbig sein kann. Zur Erzielung eines mehrfarbigen Hauptmusters wird das Papier anschliessend noch in einem weiteren Druckwerk, insbesondere einem Stichdruckwerk, bedruckt.In the case of banknote printing, a four-color security background can be produced on one side and a seven-color security background on the other side, which is particularly secure against counterfeiting due to the seven-color image produced using two completely different printing processes. On the other hand, the above-mentioned gravure printing plates, which are located on the lowermost plate cylinder 5 and the lowermost plate cylinder 12, can be used to print a single-color main pattern on each side of the paper, while all the other plate cylinders simultaneously provide a multicolored security background. In this case, the printing press described can therefore be used to carry out complete banknote printing on both sides, as is particularly suitable for banknotes of lower values, in which the main pattern can generally be monochrome. In order to achieve a multicolored main pattern, the paper is then printed in a further printing unit, in particular an engraving printing unit.

Im betrachteten Beispiel haben der Durchmesser der Gummizylinder 1, 2 und 9 und der Durchmesser der Plattenzylinder 5, 8,10,12 und 16 das Verhältnis 3:1, was am Umfang der Gummizylinder genügend Platz zur Unterbringung der erwähnten Anzahl von Plattenzylindern bietet. Das erwähnte Durchmesserverhältnis kann natürlich auch kleiner beispielsweise 2:1, oder grösser, beispielsweise 4:1, sein, wobei sich dann die Anzahl der maximal unterzubringenden Plattenzylinder entsprechend ändert. Auch kann die Anordnung der Gummizylinder 1, 2 und 9 anders als beschrieben sein. Schliesslich kann es sich bei der beschriebenen Druckmaschine auch um eine Bogendruckmaschine handeln, wobei dann entsprechende Bogenführungsorgane und an einem der Gummizylinder 1 oder 2 bekannte Bogengreifer vorgesehen sind.In the example considered, the diameter of the blanket cylinders 1, 2 and 9 and the diameter of the plate cylinders 5, 8, 10, 12 and 16 have a ratio of 3: 1, which offers enough space on the circumference of the blanket cylinders to accommodate the number of plate cylinders mentioned. The diameter ratio mentioned can of course also be smaller, for example 2: 1, or larger, for example 4: 1, in which case the number of the maximum plate cylinders to be accommodated changes accordingly. The arrangement of the rubber cylinders 1, 2 and 9 can also be different than described. Finally, the printing press described can also be a sheet-fed printing press, in which case corresponding sheet guiding members and sheet grippers known on one of the rubber cylinders 1 or 2 are then provided.

Es ist ferner möglich, dass auch der Gummizylinder 1 mit einem Sammeldruckwerk, bestehend aus einem Sammeldruckplattenzylinder, einem weiteren Gummizylinder und diesen einfärbenden Farbselektionszylinder, sowie mit einem konvertiblen und verstellbaren Plattenzylinder, analog dem Plattenzylinder 16, kombiniert wird, so dass die in der Figur linke Papierseite ebenfalls einen kombinierten Sammeldruck-Offsetdruck erhält. Die linke Seite der Druckmaschine kann dann insbesondere vollständig symmetrisch zur rechten Seite aufgebaut sein.It is also possible that the blanket cylinder 1 is also combined with a collective printing unit, consisting of a collective printing plate cylinder, a further blanket cylinder and this inking color selection cylinder, as well as with a convertible and adjustable plate cylinder, analogous to the plate cylinder 16, so that the one on the left in the figure Paper side also receives a combined batch printing offset printing. The left side of the printing press can then be constructed completely symmetrically to the right side.
