Abstract

A convertible, multicolor, printing press for printing the safety background of banknotes or the like comprises, in one configuration, an impression cylinder, a second blanket cylinder which engages the impression cylinder, a first plate cylinder which engages the second blanket cylinder and also engages a first blanket cylinder which first blanket cylinder is spaced from the impression cylinder, and several sectioned inking rollers which engage the first blanket cylinder and which are each inked by inking devices of different colors. The printing press is converted to a second configuration by exchanging the sectioned inking rollers for second plate cylinders, separating the first plate and second blanket cylinders from engagement with the first blanket (11-14) and impression cylinders respectively, and moving the impression cylinder to directly engage the first blanket cylinder. In the one configuration, a juxtaposed color image may be printed and in the second configuration, a superposed color image may be printed.

Description

Die Erfindung bezieht sich auf eine Bogen- oder Rollen-Mehrfarbenrotationsdruckmaschine, insbesondere zum Druck des Sicherheitsuntergrundes auf Wertpapieren, vor allem Banknoten, mit einem Gegendruckzylinder, einem ersten Gummizylinder, mit mehreren, durch je ein Farbwerk mit unterschiedlichen Farben eingefärbten Zylindern, welche mit dem ersten Gummizylinder zum Aufbringen eines Mehrfarbenbildes zusammenarbeiten, und mit einer Gruppe aus zwei Zylindern, bestehend aus einem Plattenzylinder, welcher eine das vollständige, zu druckende Muster aufweisende Hochdruckplatte trägt, und einem mit diesem Plattenzylinder zusammenwirkenden zweiten Gummizylinder.The invention relates to a sheet or roll multi-color rotary printing machine, in particular for printing the security background on securities, especially banknotes, with an impression cylinder, a first blanket cylinder, with several cylinders, each colored by an inking unit with different colors, which with the first Working together blanket cylinders for applying a multicolor image, and with a group of two cylinders, consisting of a plate cylinder which carries a high-pressure plate having the complete pattern to be printed, and a second blanket cylinder interacting with this plate cylinder.

In einer älteren deutschen Patentanmeldung wurde bereits eine derartige Druckmaschine vorgeschlagen, welche ein Bild mit nebeneinanderliegenden Farbzonen mittels einer einzigen Druckplatte und mehreren Schablonenwalzen herzustellen erlaubt; dieses Druckverfahren ist unter dem Namen "Orlof"-Verfahren bekannt.In an older German patent application, such a printing machine was already proposed, which allows an image with adjacent ink zones to be produced by means of a single printing plate and several stencil rollers; this printing process is known as the "Orlof" process.

Nach diesem Druckverfahren ist ein einziger Plattenzylinder mit einer Hochdruckplatte vorgesehen, welche das vollständige, zu druckende Muster aufweist. Diese Hochdruckplatte wird durch einen Sammelzylinder eingefärbt, welcher seinerseits durch Schablonenwalzen eingefärbt wird, die sektoral ausgeschnittene Schablonen in Form von farbannehmenden Erhöhungen entsprechend den verschiedenen Farbzonen aufweisen; jede Schablonenwalze überträgt die Farbe, mit der sie von ihrem eigenen Farbwerk eingefärbt wird.According to this printing process, a single plate cylinder with a high-pressure plate is provided, which has the complete pattern to be printed. These H ochdruckplatte is inked by a collecting cylinder, which is in turn inked by stencil rollers, the sectoral cut stencil in the form of ink-accepting increases correspondingly have the different color zones; each stencil roller transfers the color with which it is inked by its own inking unit.

Man erhält durch dieses Druckverfahren ein mehrfarbiges Bild, auf welchem das Register zwischen den verschiedenen Farben des Bildmusters perfekt ist; ein derartiges Resultat lässt sich mit irgendwelchen anderen Druckverfahren praktisch nicht erzielen.This printing process gives a multicolored image on which the register between the different colors of the image pattern is perfect; such a result can practically not be achieved with any other printing method.

Ferner ist der Mehrfarbendruck mit überlagerten Farben und Mustern bekannt (indirekter Hochdruck oder Offsetdruck), welcher ebenfalls häufig zum Druck des Sicherheitsuntergrundes auf Wertpapieren verwendet wird. Nach diesem Druckverfahren wird das komplette Druckmuster aus verschiedenfarbigen Teilmustern zusammengesetzt; jedes Teilmuster einer bestimmten Farbe wird durch eine Druckplatte dargestellt, die auf je einem Plattenzylinder angeordnet ist. Es entsteht hierbei eine registerhaltige Ueberlagerung der verschiedenen Farben und Muster. Die Anzahl der Druckplatten und folglich der Plattenzylinder entspricht der Zahl der verschiedenfarbigen Teilmuster, welche das vollständige mehrfarbige Bild bilden.Furthermore, multi-color printing with superimposed colors and patterns is known (indirect letterpress or offset printing), which is also often used to print the security background on securities. According to this printing process, the complete print pattern is composed of differently colored partial patterns; Each partial pattern of a certain color is represented by a printing plate, which is arranged on a plate cylinder. This creates a register-based overlay of the different colors and patterns. The number of printing plates and consequently the plate cylinders corresponds to the number of differently colored partial patterns which form the complete multicolored image.

Bisher wurden Druckmaschinen entwickelt, mit denen getrennt entweder das eine oder das andere der vorstehend beschriebenen Druckverfahren durchführbar ist.So far, printing presses have been developed with which either one or the other of the printing processes described above can be carried out separately.

Der Erfindung liegt die Aufgabe zugrunde, eine einzige Rotationsdruckmaschine zu schaffen, mit welcher man sowohl das eine als auch das andere der erwähnten Druckverfahren durchführen kann und welche auf einfachste Weise den Uebergang vom einen zum anderen Druckverfahren ermöglicht.The invention has for its object to provide a single rotary printing press, with which one can carry out both one and the other of the printing methods mentioned and which on one the most professional way to enable the transition from one printing process to another.

Diese Aufgabe wird erfindungsgemäss durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of patent claim 1.

Der Hauptvorteil der Druckmaschine nach der Erfindung ist nicht nur technischer Natur, da sie zwei vollständig unterschiedliche Druckverfahren ermöglicht, sondern auch wirtschaftlicher Natur, weil sie dem Benutzer die Wahl des Druckverfahrens bietet, ohne zwei getrennte Maschinen zu Hilfe nehmen zu müssen.The main advantage of the printing machine according to the invention is not only of a technical nature, since it enables two completely different printing processes, but also of an economic nature, because it offers the user the choice of the printing process without having to use two separate machines.

Die Umstellung der Maschine nach der Erfindung beim Uebergang von einem zum anderen Druckverfahren ist ausserordentlich einfach.The changeover of the machine according to the invention during the transition from one printing process to another is extremely simple.

Die Erfindung wird anhand der Zeichnungen an einem Ausführungsbeispiel einer Bogendruckmaschine näher erläutert.

  • Figur 1 zeigt schematisch die Lage aller Maschinenteile beim Druck nach dem "Orlof"-Verfahren, und
  • Figur 2 zeigt schematisch die Lage aller Maschinenteile beim indirekten Hochdruck oder Offsetdruck.
The invention is explained in more detail with reference to the drawings using an exemplary embodiment of a sheet-fed printing machine.
  • Figure 1 shows schematically the position of all machine parts when printing according to the "Orlof" process, and
  • Figure 2 shows schematically the position of all machine parts in indirect high pressure or offset printing.

Die beiden Figuren 1 und 2 unterscheiden sich lediglich in der Anordnung einiger Teile der Druckmaschine, und daher sind in beiden Figuren die jeweils selben Maschinenteile mit den gleichen Bezugszeichen bezeichnet.The two Figures 1 and 2 differ only in the arrangement of some parts of the printing press, and therefore in both figures the same machine parts are designated by the same reference numerals.

Die Druckmaschine hat eine bekannte Bogenzuführungsvorrichtung 1, welche einen nicht dargestellten Schuppenanleger, eine Stopptrommel 2, eine Ueberführungstrommel 3 und eine Papierentstaubungs- und Antistatikvorrichtung 5 aufweist. Wahlweise kann ein Bogenrandnumerierwerk 4 vorgesehen sein. Die Bogen gelangen auf einen Gegendruckzylinder 6, welcher sich in Pfeilrichtung dreht, und werden nach der Bedruckung durch ein Kettengreifersystem 20 zu einer Bogenauslage oder aber zu einer weiteren Druckmaschine zwecks Be-druckung der anderen Bogenseite transportiert.The printing press has a known sheet feed device 1, which has a scale feeder (not shown), a stop drum 2, a transfer drum 3 and a paper dusting and A ntistatikvorrichtung 5 has. Optionally, a B may be provided ogenrandnumerierwerk. 4 The sheets arrive to a counter-pressure cylinder 6, which rotates in the direction of the arrow, and transported after printing by a chain gripper system 20 to a sheet delivery or to a further printing machine for the purpose of B e-druckung the other side of the sheet.

Die auf dem Gegendruckzylinder 6 befindlichen Bogen können gemäss der Erfindung entweder nach dem "Orlof"-Verfahren (Figur 1) oder im indirekten Hochdruck oder Offsetdruck (Figur 2) bedruckt werden, und zwar vorzugsweise zur Erzeugung eines mehrfarbigen Sicherheitsuntergrundes auf der einen Seite eines Wertpapiers. Zu diesem Zwecke weist die Druckmaschine einen Gummizylinder 7 auf, welcher in beiden Fällen, jedoch auf unterschiedliche Weise verwendet wird.The sheets on the impression cylinder 6 can be printed according to the invention either by the "Orlof" process (FIG. 1) or in indirect letterpress or offset printing (FIG. 2), preferably to produce a multicolored security background on one side of a security . For this purpose, the printing press to a G ummizylinder 7, which is used, however, in both cases, in different ways.

Beim "Orlof"-Verfahren ist der Gegendruckzylinder 6 vom Gummizylinder 7 abgerückt (Figur 1). In der Praxis ist eine derartige Abstellung des Gegendruckzylinders 6 vom Gummizylinder 7 leicht mit Hilfe eines Exzenters 6b zu erreichen, auf welchem der Körper des Gegendruckzylinders 6 montiert ist. Eine derartige Montage mit Hilfe eines Exzenters ist zur Einstellung des Anpressdruckes und zur Abstellung zweier nicht in Funktion befindlicher Zylinder bekannt; wenn der Exzenter gedreht wird, dann verschiebt sich entsprechend die Achse des betreffenden Zylinders. Es können also für diese Abrückung bereits bei bestehenden Maschinen bekannte Mittel verwendet werden. Wenn die beiden Zylinder voneinander getrennt sind, dann ist der Abstand zwischen ihnen sehr klein, im allgemeinen nur ein oder mehrere Millimeter; der in Figur 1 dargestellte Abstand ist stark übertrieben.In the "Orlof" process, the impression cylinder 6 has moved away from the blanket cylinder 7 (FIG. 1). In practice, such a shifting of the impression cylinder 6 from the blanket cylinder 7 can easily be achieved with the aid of an eccentric 6b on which the body of the impression cylinder 6 is mounted. Such assembly with the aid of an eccentric is known for adjusting the contact pressure and for turning off two cylinders that are not in operation; when the eccentric is turned, the axis of the cylinder in question shifts accordingly. Means already known for existing machines can be used for this dislocation. If the two cylinders are separate, the distance between them is very small, generally only one or more millimeters; the distance shown in Figure 1 is greatly exaggerated.

Der Gummizylinder 7 wirkt im betrachteten Beispiel nach Figur 1 mit vier Schablonenwalzen 8 zusammen, welche sektoral ausgeschnittene reliefartige Erhöhungen 8a entsprechend der Kontur der in der betreffenden Farbe zu druckenden Zonen aufweisen; jede dieser Erhöhungen 8a wird ihrerseits durch ein der betreffenden Schablonenwalze 8 zugeordnetes Farbwerk 9 eingefärbt. Diese Schablonenwalzen 8 mit ihren farbannehmenden Erhöhungen 8a sind vorzugsweise aus einem harten Material gefertigt, welches sich selbst im Falle sehr feiner ausgeschnittener Reliefs nicht verformt, so dass ein Sicherheitsuntergrund aus sehr feinen Linien herstellbar ist. Die den Konturen der Erhöhungen 8a entsprechenden Zonen der vier Farben werden auf den Gummizylinder 7 übertragen, welcher als Sammelzylinder fungiert, der diese Farbzonen nebeneinander vereinigt und auf die Druckplatte 10a eines einzigen Plattenzylinders 10 überträgt. Diese Druckplatte 10a ist eine Hochdruckplatte und weist das vollständige, in vier Farben zu druckende Muster auf. Das vollständige, in den verschiedenen Farben eingefärbte Bild wird seinerseits auf einen Gummizylinder 11 übertragen, der einen kleineren Durchmesser als der Gummizylinder 7 hat und mit dem Gegendruckzylinder 6 zusammenwirkt, um das vollständige Bild auf das Papier zu drucken.In the example considered according to FIG. 1, the rubber cylinder 7 interacts with four stencil rollers 8, which have sector-like relief-like elevations 8a corresponding to the contour of the zones to be printed in the relevant color; each of these elevations 8a is in turn inked by an inking unit 9 assigned to the relevant stencil roller 8. These stencil rollers 8 with their ink-accepting elevations 8a are preferably made of a hard material which does not deform even in the case of very finely cut reliefs, so that a security base can be produced from very fine lines. The zones of the four colors corresponding to the contours of the elevations 8a are transferred to the rubber cylinder 7, which functions as a collecting cylinder which combines these color zones next to one another and transfers them to the printing plate 10a of a single plate cylinder 10. This printing plate 10a is a high-pressure plate and has the complete pattern to be printed in four colors. The complete image, colored in the different colors, is in turn transferred to a rubber cylinder 11, which has a smaller diameter than the rubber cylinder 7 and cooperates with the impression cylinder 6 in order to print the complete image on the paper.

Die Maschine weist ausserdem zwei in Berührung befindliche Farbübertragungszylinder 12 und 13 auf, welche dasselbe Bild der auf dem Gummizylinder 7 befindlichen Farbzonen noch einmal von diesem Gummizylinder 7 registerhaltig auf den Plattenzylinder 10 übertragen, wodurch die Einfärbung der Druckplatte 10a verstärkt wird und demzufolge diese Zonen mit den betreffenden Farben besser gedeckt werden. Gemäss der Drehrichtung des Gummizylinders 7 erfolgt zunächst eine Uebertragung des grössten Teils der Farben direkt auf die Druckplatte 10a des Plattenzylinders 10, während die restliche Farbe dann registerhaltig mittels der Farbübertragungszylinder 12 und 13 übertragen wird.The machine also has two ink transfer cylinders 12 and 13 in contact, which transfer the same image of the ink zones located on the blanket cylinder 7 from this blanket cylinder 7 to the plate cylinder 10 in register, thereby intensifying the inking of the printing plate 10a and consequently these zones the colors in question are better covered. According to the direction of rotation of the blanket cylinder 7, the majority of the colors are first transferred directly to the printing plate 10a of the plate cylinder 10, while the residual ink is then transferred in register by means of the F arbübertragungszylinder 12 and 13. FIG.

Im betrachteten Beispiel findet, wenn das Papier über den Gegendruckzylinder 6 läuft, nach dem im "Orlof"-Verfahren durchgeführten Druck im selben Arbeitsgang ein weiterer Druck im Feuchtoffsetverfahren statt. Dieser Feuchtoffsetdruck dient insbesondere zum Aufdrucken des einfarbigen Hauptmusters auf einem Wertschein. Das Feuchtoffsetsystem weist einen eine Tiefdruckplatte tragenden Plattenzylinder 14, ein Farbwerk 15 und ein an sich bekanntes Feuchtwerk 16 auf, wobei der Tiefdruckzylinder 14 mit einem Gummizylinder 17 zusammenwirkt, welcher das Bild auf das Papier überträgt. Im betrachteten Falle erhält man also in einem einzigen Druckvorgang einen vollständigen Druck auf einer Wertscheinseite, nämlich den vierfarbigen Sicherheitsuntergrund durch einen Druck nach dem "Orlof"-Verfahren und das einfarbige Hauptmuster durch einen Feuchtoffsetdruck.In the example under consideration, when the paper runs over the impression cylinder 6, after the printing carried out in the "Orlof" process, a further printing takes place in the same operation in the wet offset process. This wet offset printing is used in particular to print the single-color main pattern on a bill. The dampening offset system has a plate cylinder 14 carrying an intaglio printing plate, an inking unit 15 and a dampening unit 16 known per se, the intaglio printing cylinder 14 cooperating with a rubber cylinder 17 which transfers the image onto the paper. In the case under consideration, one receives a complete print on a banknote page in a single printing process, namely the four-color security background by printing according to the "Orlof" process and the single-color main pattern by wet offset printing.

Im betrachteten Beispiel beträgt das Verhältnis der Durchmesser der Zylinder 8, 10, 11, 12, 13, 14 und 17 einerseits und der Zylinder 6 und 7 andererseits 1 : 3; der Umfang der Zylinder 6 und 7 entspricht also den Abmessungen dreier Papierbogen, und entsprechend sind der Gummizylinder 7 und der Gegendruckzylinder 6 mit jeweils drei Gummitüchern 7a bzw. 6a belegt, während der Gummizylinder 11 und die Farbübertragungszylinder 12 und 13 nur je ein Gummituch lla, 12a bzw. 13a tragen.In the example considered, the ratio of the diameters of the cylinders 8, 10, 11, 12, 13, 14 and 17 on the one hand and the cylinders 6 and 7 on the other hand is 1: 3; the circumference of the cylinders 6 and 7 thus corresponds to the dimensions of three sheets of paper, and accordingly the blanket cylinder 7 and the impression cylinder 6 are each covered with three blankets 7a and 6a, while the blanket cylinder 11 and the ink transfer cylinders 12 and 13 each have only one blanket lla, Wear 12a or 13a.

Gemäss einer Variante ist es auch möglich, die Lagen des Plattenzylinders 10 und des Gummizylinders 11 zu vertauschen. In diesem Falle findet der Druck auf das Papier direkt durch den Plattenzylinder 10 statt, wobei die Einfärbung der Druckplatte 10a durch den Gummizylinder 11 erfolgt, welcher seinerseits sowohl mit dem Gummizylinder 7 als auch dem Uebertragungszylinder 13 in Berührung steht.According to a variant, it is also possible to interchange the positions of the plate cylinder 10 and the rubber cylinder 11. In this case, the printing on the paper takes place directly through the plate cylinder 10, with the inking of the printing plate 10a by the rubber cylinder 11 takes place, which in turn is in contact with both the blanket cylinder 7 and the transfer cylinder 13.

Für den Fall, dass dieselbe Maschine für einen indirekten Hochdruck oder Offsetdruck verwendet werden soll (Figur 2), genügt es, die Schablonenwalzen 8, 8a durch Druckplatten 8b tragende Plattenzylinder 8 zu ersetzen, den Gummizylinder 11 vom Gegendruckzylinder 6 abzustellen, ferner den Plattenzylinder 10 und den Farbübertragungszylinder 12 vom Gummizylinder 7 abzustellen und den Gegendruckzylinder 6 an den Gummizylinder 7 anzustellen, damit sich diese beiden Zylinder berühren. Die Druckplatten 8b sind Hochdruckplatten, wie sie beim Trockenoffsetdruck verwendet werden, und weisen Teilmuster auf, die, wie im vorhergehenden Falle, durch Farbwerke 9 eingefärbt werden. Diese verschiedenfarbigen Teilmuster werden registerhaltig auf dem Gummizylinder 7 vereinigt, welcher in diesem Falle als Sammelzylinder für die das mehrfarbige Gesamtbild bildenden Teilmuster fungiert. Man erhält auf diese Weise beim Durchgang des Papiers zwischen dem Gegendruckzylinder 6 und dem Gummizylinder 7 einen vierfarbigen Trockenoffsetdruck. Dieser mehrfarbige Offsetdruck kann ebenfalls, wie vorstehend erläutert, durch einen einfarbigen Feuchtoffsetdruck mit Hilfe des Tiefdruckzylinders 14 und des Gummizylinders 17 ergänzt werden.In the event that the same machine is to be used for indirect high-pressure or offset printing (FIG. 2), it is sufficient to replace the stencil rollers 8, 8a with plate cylinders 8 carrying printing plates 8b, to switch off the rubber cylinder 11 from the impression cylinder 6, and also the plate cylinder 10 and F shut arbübertragungszylinder 12 from the blanket cylinder 7 and to make the impression cylinder 6 to the blanket cylinder 7, so that they touch the two cylinders. The printing plates 8b are high-pressure plates, as are used in dry offset printing, and have partial patterns which, as in the previous case, are colored by inking units 9. These differently colored partial patterns are combined in register on the rubber cylinder 7, which in this case functions as a collecting cylinder for the partial patterns forming the multicolored overall picture. In this way, four-color dry offset printing is obtained when the paper passes between the impression cylinder 6 and the blanket cylinder 7. This multi-color offset printing can also, as explained above, by a single-color wet offset printing using the T iefdruckzylinders 14 and the blanket cylinder 17 to be added.

Die Einstellung des Abstandes zwischen den verschiedenen Zylindern, d.h. zwischen dem Gegendruckzylinder 6 und dem Gummizylinder 7, zwischen dem Gummizylinder 11 und dem Gegendruckzylinder 6, zwischen den Zylindern 10 und 12 und dem Gummizylinder 7, sowie die erforderlichen Verschiebungen der anderen, mit diesen Zylindern zusammenwirkenden Zylinder lässt sich durch bekannte Einstellmittel erreichen, insbesondere indem alle Zylinder auf Exzenterbüchsen montiert werden, wie es bereits für den Gegendruckzylinder 6 erwähnt wurde. Die Abstände zwischen nicht zusammenwirkenden Zylindern sind sehr klein und betragen Grössenordnungsmässig im allgemeinen nur einige Millimeter.The adjustment of the distance between the different cylinders, that is, between the impression cylinder 6 and the blanket cylinder 7, between the blanket cylinder 11 and the impression cylinder 6, between the cylinders 10 and 12 and the blanket cylinder 7, as well as the necessary displacements of the other, interacting with these cylinders Cylinder can be reached by known adjustment means, especially by all Cylinder can be mounted on eccentric bushes, as has already been mentioned for the impression cylinder 6. The distances between non-interacting cylinders are very small and generally only a few millimeters in size.

Während eines Offsetdrucks werden der Plattenzylinder 10, der Gummizylinder 11 und die Farbübertragungszylinder 12 und 13 nicht verwendet und daher durch Entkupplung vom Antriebssystem der Maschine stillgesetzt.During an offset printing, the plate cylinder 10, the blanket cylinder 11 and the ink transfer cylinders 12 and 13 are not used and are therefore stopped by decoupling from the drive system of the machine.

Selbstverständlich kann im Rahmen der Erfindung auf das beschriebene Feuchtoffsetsystem verzichtet werden, jedoch erlaubt es dieses System, wie erwähnt, einen vollständigen Druck auf der einen Seite eines Wertpapiers zu erhalten.Of course, the described wet offset system can be dispensed with in the context of the invention, but, as mentioned, this system allows a complete print to be obtained on one side of a security.

Ausserdem können die Schablonenwalzen 8, 8a, welche zur Einfärbung des Gummizylinders 7 beim Druck nach dem "Orlof"-Verfahren bestimmt sind, durch Einfärbeschablonen bzw. durch Farbkonturplatten ersetzt werden, welche auf den eigentlichen Rollen bzw. Zylindern befestigbar sind. In diesem Falle genügt es also beim Uebergang von einen zum anderen Druckverfahren, lediglich auf den mit dem Gummizylinder 7 zusammenwirkenden Zylindern 8 die Einfärbeschablonen durch Druckplatten zu ersetzen oder umgekehrt, während die Zylinder bzw. Rollen selber unverändert bleiben und nicht gewechselt zu werden brauchen.In addition, the stencil rollers 8, 8a, which are intended for inking the blanket cylinder 7 when printing according to the "Orlof" method, can be replaced by inking stencils or by color contour plates which can be attached to the actual rollers or cylinders. In this case, when changing from one printing process to the other, it is sufficient to replace the inking stencils with printing plates only on the cylinders 8 interacting with the rubber cylinder 7, or vice versa, while the cylinders or rollers themselves remain unchanged and do not need to be replaced.
