Description

Die Erfindung betrifft Verfahren zur Herstellung eines Wertdokuments, das ein transluzentes Substrat mit einer Vorderseite und einer Rückseite aufweist, wobei auf der Vorderseite eine erste Information und auf der Rückseite eine zweite Information angeordnet wird, wobei die zweite Information im Passer zu der ersten Information angeordnet wird.The invention relates to a method for producing a document of value which has a translucent substrate with a front and a back, first information being arranged on the front and second information being arranged on the back, the second information being arranged in register with the first information .

Es ist bekannt, dass man die Oberflächenspannung von Farben, Lacken und Beschichtungen über Additive beeinflussen kann. Insbesondere die Hydrophobierung bestehender Farben und Lacke wird in der Praxis eingesetzt, um die Benetzung auf Substraten oder Vordrucken zu verbessern. Zur Hydrophobierung eignen sich beispielsweise Silikonöle oder Wachse. Weiterhin ist in der Praxis bekannt, durch eine Hydrophobierung von Lacken die Schmutzabweisung zu verbessern. Bei UV-trocknenden Lacken setzt man hierzu zum Teil UV-vernetzende Silikonharze ein.It is known that the surface tension of paints, varnishes and coatings can be influenced by additives. In particular, the hydrophobization of existing paints and varnishes is used in practice to improve wetting on substrates or preprints. For example, silicone oils or waxes are suitable for hydrophobing. It is also known in practice to improve the dirt repellency by making paints hydrophobic. In the case of UV-drying lacquers, UV-crosslinking silicone resins are sometimes used for this purpose.

Weiterhin ist bekannt, dass bestimmte Effektfarben ihre Farbigkeit nur auf dunklen Untergründen oder/und bei bestimmten Kippwinkeln zeigen. Hierzu zählen beispielsweise Farben mit Flüssigkristall-Pigmenten (LCP) oder mit Iriodin-Pigmenten. Iriodin-Pigmente sind Interferenzpigmente der Fa. Merck, die überwiegend aus glimmerbasierten Perlglanzpigmenten bestehen.It is also known that certain effect colors only show their color on dark backgrounds and / or at certain tilt angles. These include, for example, colors with liquid crystal pigments (LCP) or with Iriodin pigments. Iriodin pigments are interference pigments from Merck, which mainly consist of mica-based pearlescent pigments.

Des Weiteren ist beispielsweise aus den Druckschriften WO 2006/015733 A1 und WO 2013/124059 A1 bekannt, dass mittels Laserstrahlen Farben oder Beschichtungen ablatiert bzw. abgetragen werden oder in ihrer Struktur oder Sichtbarkeit modifiziert werden, wenn diese im Wellenlängenbereich der Laserstrahlung eine Absorption zeigen.
Im Banknotendruck ist die Supersimultandruckmaschine Stand der Technik, mit der es möglich ist, einen mehrfarbigen Vorderseitendruck gepassert zum Rückseitendruck zu realisieren, da bei dieser Maschine der Druck aller Farben auf Vorder- und Rückseite des Substrats gleichzeitig erfolgt. Das Substrat wird dabei zwischen zwei Gummituchzylindern geführt, wobei jeder dieser Gummituchzylinder gleichzeitig die Aufgabe eines Gegendruckzylinders für den gegenüberliegenden Farbtransferzylinder wahrnimmt. Selbstverständlich erfüllen auch andere Druckmaschinen die Voraussetzung, wenn nach dem Prinzip "blanket to blanket" verfahren wird. Bei diesen Maschinen wird mittels Farbauftragswalzen eine Hochdruck-, Toray- (auch wasserbasierter Effektdruck genannt) oder Offsetdruckplatte eingefärbt und das Motiv von der Druckplatte auf den Gummituchzylinder (bei Rollendruckmaschinen kann der Gummituchzylinder auch eine Gummiwalze sein) übertragen.Furthermore, for example, from the publications WO 2006/015733 A1 and WO 2013/124059 A1 It is known that colors or coatings are ablated or removed by means of laser beams or modified in their structure or visibility if they show absorption in the wavelength range of the laser radiation.
In banknote printing, the super-simultaneous printing machine is state of the art, with which it is possible to print a multicolored front side print in register Realize back side printing, because with this machine the printing of all colors on the front and back side of the substrate takes place at the same time. The substrate is guided between two blanket cylinders, each of these blanket cylinders simultaneously performing the task of an impression cylinder for the opposite ink transfer cylinder. Of course, other printing machines also meet the requirement if the "blanket to blanket" principle is used. With these machines, a high-pressure, Toray (also called water-based effect printing) or offset printing plate is inked using inking rollers and the motif is transferred from the printing plate to the blanket cylinder (on web printing machines the blanket cylinder can also be a rubber roller).

Druckfarben, die Effektpigmente enthalten, werden auch als Effektfarben bezeichnet. Der Druck dieser Effektpigmente auf das Substrat erfolgt in der Regel mit einer separaten Druckmaschine, üblicherweise im Tief-, Flexo- oder Siebdruck, um einen optimalen optischen Effekt zu erreichen. Dies hat seine Ursache beispielsweise in der besonderen Größe der Effektpigmente, der Form (z.B. plättchenförmig) und der Notwendigkeit einer planparallelen Orientierung der Pigmente in Bezug auf die Oberfläche des Substrats. Der Druck mit einer separaten Druckmaschine hat jedoch den Nachteil, dass es bedingt durch eine neue Anlage des Substrats und möglichen weiteren mechanischen Übergaben zwangsläufig zu Passerschwankungen zwischen den mit verschiedenen Druckverfahren erzeugten Aufdrucken kommt. Die Passerschwankungen können je nach Qualität der Druckmaschine und des Substrats (Planlage, Dimensionsstabilität), der Substratgröße, der aktiven Trocknung der Farbe (UV-Trockner, Heißluft-/IR-Trockner) usw. wenige Millimeter betragen und sind damit auch für Laien erkennbar.Printing inks that contain effect pigments are also referred to as effect colors. These effect pigments are usually printed on the substrate using a separate printing machine, usually using gravure, flexographic or screen printing, in order to achieve an optimal optical effect. This is due, for example, to the particular size of the effect pigments, the shape (for example platelet-shaped) and the need for a plane-parallel orientation of the pigments in relation to the surface of the substrate. Printing with a separate printing machine, however, has the disadvantage that a new installation of the substrate and possible further mechanical transfers inevitably lead to register fluctuations between the imprints produced with different printing processes. The register fluctuations can amount to a few millimeters, depending on the quality of the printing machine and the substrate (flatness, dimensional stability), the substrate size, the active drying of the ink (UV dryer, hot air / IR dryer), etc. and are therefore also noticeable to laypeople.

Werden sowohl auf der Vorder- wie auch auf der Rückseite eines Substrats Effektfarben gedruckt, so werden die Effektfarben üblicherweise in unterschiedlichen Druckschritten aufgebracht, was zu einer weiteren Erhöhung der Passerschwankungen führt. Diese Passerproblematik ergibt sich auch dann, wenn Folienelemente und Druckbilder mit unterschiedlichen Verfahren und unterschiedlichen Maschinen auf das Substrat aufgebracht werden.If effect colors are printed on both the front and the back of a substrate, the effect colors are usually applied in different printing steps, which leads to a further increase in register fluctuations. This registration problem also arises when film elements and printed images are applied to the substrate using different methods and different machines.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein gattungsgemäßes Verfahren zur Herstellung eines Wertdokuments derart weiterzubilden, dass die Nachteile des Standes der Technik behoben und der Schutz gegenüber Fälschungen weiter erhöht wird.The invention is therefore based on the object of developing a method of the generic type for producing a document of value in such a way that the disadvantages of the prior art are eliminated and the protection against forgery is further increased.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst.This object is achieved by the features of the independent claims.

Erfindungsgemäß wird zunächst ein transluzentes Substrat zur Verfügung gestellt, das eine Vorderseite und eine Rückseite aufweist. Anschließend wird auf die Vorderseite des Substrats eine erste Information und auf die Rückseite des Substrats eine zweite Information aufgebracht, wobei die zweite Information im Passer zu der ersten Information angeordnet wird. Anschließend wird mindestens eine dritte Information auf die Vorderseite und/oder Rückseite des Substrats aufgebracht, wobei die mindestens eine dritte Information mindestens teilweise über der ersten Information und/ oder zweiten Information angeordnet wird. Im letzten erfindungsgemäßen Verfahrensschritt wird ein Passer zwischen der mindestens einen dritten Information und der ersten Information und/ oder zweiten Information hergestellt.According to the invention, a translucent substrate is first made available, which has a front side and a rear side. First information is then applied to the front side of the substrate and second information is applied to the rear side of the substrate, the second information being arranged in register with the first information. At least one third item of information is then applied to the front side and / or rear side of the substrate, the at least one third information is arranged at least partially over the first information and / or second information. In the last method step according to the invention, a register is produced between the at least one third piece of information and the first piece of information and / or second piece of information.

Bei dem mit dem erfindungsgemäßen Verfahren hergestellten Wertdokument ist somit auf der Vorderseite und/ oder Rückseite des Substrats mindestens eine dritte Information angeordnet, welche mindestens teilweise zu der ersten Information und/ oder zweiten Information überlappend angeordnet ist, wobei die mindestens eine dritte Information im Passer zu der ersten Information und/ oder zweiten Information angeordnet ist.In the value document produced with the method according to the invention, at least one third piece of information is thus arranged on the front and / or back of the substrate, which is arranged at least partially overlapping the first piece of information and / or second piece of information, the at least one third piece of information in the register the first information and / or second information is arranged.

Einer der Grundgedanken der Erfindung liegt hierbei darin, dass an sich nicht im Passer applizierbare Beschichtungen im Passer zueinander gebracht werden.One of the basic ideas of the invention is that coatings that cannot be applied in register are brought together in register.

Als Passer oder Register im Sinne dieser Erfindung wird die Lagegenauigkeit von Druckbildern oder anderer Elemente zueinander auf Vorder- und/ oder Rückseite eines Substrats bezeichnet. Beispielsweise stören bei Teilen von Druckbildern, die sich in Durchsicht zu einem Gesamtdruckbild ergänzen, bereits geringe Abweichungen von weniger als 0,1 mm zwischen den jeweiligen Druckbildern den visuellen Eindruck in Durchsicht erheblich. Die DIN 16500-2: 1987-01 definiert als Passer die Genauigkeit in der Drucktechnik, mit der die vorgesehene Wiedergabegüte der zu reproduzierenden Details erreicht bzw. eingehalten wird.In the context of this invention, the positional accuracy of printed images or other elements with respect to one another on the front and / or back of a substrate is referred to as register. For example, in the case of parts of printed images which, when viewed through, complement one another to form an overall printed image, even slight deviations of less than 0.1 mm between the respective printed images significantly disturb the visual impression when viewed through. DIN 16500-2: 1987-01 defines register as the accuracy in printing technology with which the intended reproduction quality of the details to be reproduced is achieved or maintained.

Durchsicht liegt vor, wenn die Beleuchtung des Substrats von der einen Seite und die Betrachtung von der anderen Seite erfolgt. Aufsicht liegt vor, wenn die Beleuchtung und Betrachtung von derselben Seite des Substrats aus erfolgt.See-through is present when the substrate is illuminated from one side and viewed from the other side. Supervision exists if the illumination and viewing are from the same side of the substrate.

Transluzenz im Sinne dieser Erfindung bedeutet, dass ein Objekt, wie beispielsweise das Substrat, auftreffendes Licht nur zu einem bestimmten Anteil hindurchtreten lässt. Trifft Licht auf eine Seite des Objekts auf, wird ein bestimmter Anteil des Lichtes bis zu der anderen Seite des Objekts hindurchgelassen und tritt dort wieder aus. Je größer der prozentuale Anteil des hindurchtretenden Lichtes bezogen auf das auftreffende Licht ist, desto transluzenter ist das Objekt.Translucency in the context of this invention means that an object, such as the substrate, allows incident light to pass through only to a certain extent. If light hits one side of the object, a certain proportion of the light is let through to the other side of the object and exits there again. The greater the percentage of the light passing through in relation to the incident light, the more translucent the object.

Ein transluzentes Objekt ist im Sinne dieser Erfindung jedoch weder transparent noch opak. Ein Objekt wird hierbei als transparent bezeichnet, wenn der prozentuale Anteil des durch das Objekt hindurchtretenden Lichts in Bezug auf das auf das Objekt auftreffende Licht bei mindestens 90 % liegt, d.h. das Objekt lässt das auftreffende Licht wie bei einem Fenster oder einer Öffnung nahezu ungeschwächt hindurchtreten. Ein Objekt hingegen, das weniger als 10 % und bevorzugt etwa 0 % des auftreffenden Lichtes hindurchtreten lässt, d.h. bei dem der Anteil des hindurchtretenden Lichtes bezogen auf das auftreffende Licht gering oder nahe oder gleich null ist, wird als opak oder als nicht lichtdurchlässig bezeichnet.For the purposes of this invention, however, a translucent object is neither transparent nor opaque. An object is referred to as transparent if the percentage of the light passing through the object in relation to the light hitting the object is at least 90%, i.e. the object allows the light to pass through almost without being weakened like a window or an opening . On the other hand, an object that allows less than 10% and preferably about 0% of the incident light to pass through, i.e. in which the proportion of the light passing through is low, close to or equal to zero in relation to the incident light, is referred to as opaque or non-translucent.

Das Substrat kann als einlagiges oder mehrlagiges Sicherheitspapier ausgeführt sein. Mehrlagiges Sicherheitspapier enthält zumindest eine Lage aus Papier. Die weiteren Lagen können ebenfalls aus Papier, aber auch aus anderen Materialien, beispielsweise durch Kunststofffolien, gebildet sein. Das Sicherheitspapier besteht besonders bevorzugt aus Baumwollfasern, wie es beispielsweise für Banknoten verwendet wird.The substrate can be designed as a single-ply or multi-ply security paper. Multi-ply security paper contains at least one ply of paper. The further layers can also be made of paper, but also of other materials, for example plastic films. The security paper is particularly preferably made of cotton fibers, such as is used for bank notes, for example.

Bevorzugt kann das Substrat auch aus Papier aus anderen natürlichen Fasern, ebenso bevorzugt aus Synthesefasern oder einer Mischung aus natürlichen und synthetischen Fasern bestehen. Weiterhin bevorzugt besteht das Substrat aus einer Kombination aus mindestens zwei übereinander angeordneten und miteinander verbundenen unterschiedlichen Substraten, einem sogenannten Hybrid, beispielsweise einer Kombination Kunststofffolie-Papier-Kunststofffolie, d.h. ein Substrat aus Papier wird auf jeder seiner beiden Seiten durch eine Kunststofffolie bedeckt, oder Papier-Kunststofffolie-Papier, d.h. ein Substrat aus einer Kunststofffolie wird auf jeder seiner beiden Seiten durch ein Substrat aus Papier bedeckt.The substrate can preferably also consist of paper made from other natural fibers, also preferably from synthetic fibers or a mixture of natural and synthetic fibers. Furthermore, the substrate preferably consists of a combination of at least two superposed and interconnected different substrates, a so-called hybrid, for example a combination of plastic film-paper-plastic film, ie a substrate made of paper is covered on each of its two sides by a plastic film, or paper -Plastic film paper, ie a substrate made of a plastic film is covered on each of its two sides by a substrate made of paper.

Angaben zum Gewicht des verwendeten Substrats (unbedruckt und unbeschichtet) sind beispielsweise in der Schrift DE 102 43 653 A9 angegeben, deren Ausführungen diesbezüglich vollumfänglich in diese Anmeldung aufgenommen werden. Die Schrift DE 102 43 653 A9 führt insbesondere aus, dass die Papierschicht üblicherweise ein Gewicht von 50 g/m2 bis 100 g/m2 aufweist, vorzugsweise von 80 g/m2 bis 95 g/m2. Selbstverständlich kann je nach Anwendung jedes geeignete Gewicht eingesetzt werden.Information on the weight of the substrate used (unprinted and uncoated) is given, for example, in the text DE 102 43 653 A9 specified, the explanations of which are fully included in this application. The font DE 102 43 653 A9 states in particular that the paper layer usually has a weight of 50 g / m 2 to 100 g / m 2 , preferably 80 g / m 2 to 95 g / m 2 . Of course, any suitable weight can be used depending on the application.

Wertdokumente, in denen ein derartiges Substrat bzw. Sicherheitspapier verwendet werden kann, sind insbesondere Banknoten, Aktien, Anleihen, Urkunden, Gutscheine, Schecks, hochwertige Eintrittskarten, aber auch andere fälschungsgefährdete Papiere, wie Pässe und sonstige Ausweisdokumente, sowie Karten, wie beispielsweise Kredit- oder Debitkarten, deren Kartenkörper mindestens eine Lage eines Sicherheitspapiers aufweist, und auch Produktsicherungselemente, wie Etiketten, Siegel, Verpackungen und dergleichen.Documents of value in which such a substrate or security paper can be used are, in particular, banknotes, stocks, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other forgery-prone papers, such as passports and other identification documents, as well as cards, such as credit cards. or debit cards, the card body of which has at least one layer of security paper, and also product security elements such as labels, seals, packaging and the like.

Die vereinfachte Benennung Wertdokument schließt alle oben genannten Materialien, Dokumente und Produktsicherungsmittel ein.The simplified designation of value document includes all of the above materials, documents and product security means.

Die Begriffe "Vorderseite" oder "Rückseite" des Substrats oder Wertdokuments sind relative Begriffe, die auch als "die eine" und "die gegenüberliegende" Seite bezeichnet werden können und die den überwiegenden Anteil der Gesamtoberfläche des Substrats oder Wertdokuments bilden. Ausdrücklich nicht umfasst mit diesen Begriffen sind die Seitenflächen eines Substrats oder Wertdokuments, die bei einer Dicke eines Substrats oder Wertdokuments, die bei Kartenkörpern nur etwa einen Millimeter oder bei Banknoten nur Bruchteile eines Millimeters beträgt, verschwindend gering sind und üblicherweise nicht mit Sicherheitselementen oder Beschichtungen versehen werden bzw. werden können. Insbesondere können mit den Seitenflächen auch keine Durchsichtseffekte erzielt werden.The terms “front side” or “back side” of the substrate or value document are relative terms which can also be referred to as “one” and “the opposite” side and which form the predominant part of the total surface of the substrate or value document. These terms expressly do not include the side surfaces of a substrate or document of value which, with a thickness of a substrate or document of value that is only about one millimeter for card bodies or only fractions of a millimeter for banknotes, are negligible and are usually not provided with security elements or coatings will or can become. In particular, no see-through effects can be achieved with the side surfaces.

Eine Information im Sinne dieser Erfindung ist eine musterförmig gestaltete und visuell wahrnehmbare Beschichtung. Diese kann beispielsweise eine graphische Abbildung, ein Bild, eine Zahl, ein Buchstabe, ein Text oder sonstige Zeichen bilden. Besonders bevorzugt besteht die Information dabei aus positiven oder/und negativen Motiven. Bei einem positiven Motiv wird hierbei ein Motivelement selbst auf das Substrat aufgebracht, wohingegen bei einem negativen Motiv der das Motivelement umgebende Bereich auf das Substrat aufgebracht wird. Ein positives Motiv ist beispielsweise ein in dunkler Farbe auf das helle Substrat aufgedruckter Buchstabe. Ein negatives Motiv ist beispielsweise eine in dunkler Farbe auf das Substrat aufgebrachte Fläche, die innerhalb der Fläche einen unbedruckten Bereich in Form eines Buchstabens aufweist.Information within the meaning of this invention is a visually perceptible coating designed in the form of a pattern. This can, for example, form a graphic image, an image, a number, a letter, a text or other characters. The information particularly preferably consists of positive and / or negative motifs. In the case of a positive motif, a motif element itself is applied to the substrate, whereas in the case of a negative motif, the area surrounding the motif element is applied to the substrate. A positive motif is, for example, a letter printed in dark color on the light-colored substrate. A negative motif is, for example, an area applied to the substrate in a dark color, which has an unprinted area in the form of a letter within the area.

Mit Hilfe der Erfindung ergibt sich besonders vorteilhaft ein Wertdokument, das in Aufsicht auf der Vorderseite ein erstes Motiv, das aus der ersten und der dritten Information gebildet wird, und auf der Rückseite ein zweites Motiv, das aus der zweiten und gegebenenfalls dritten Information gebildet wird, sowie in Durchsicht ein drittes Motiv zeigt, wobei sich das dritte Motiv durch Überlagerung des ersten und des zweiten Motivs ergibt.With the help of the invention, a document of value results particularly advantageously, which in plan view has a first motif on the front, which is formed from the first and third information, and on the back, a second motif, which is formed from the second and optionally third information as well as showing a third motif in transparency, the third motif resulting from the superimposition of the first and second motif.

Gemäß einer besonders bevorzugten Ausführungsform besteht die Beschichtung aus einer Druckfarbe, die mittels einem aus dem Stand der Technik bekannten Druckverfahren auf das Substrat aufgedruckt wird.According to a particularly preferred embodiment, the coating consists of a printing ink which is printed onto the substrate by means of a printing method known from the prior art.

Gemäß einer ersten erfindungsgemäßen Ausführungsform wird im letzten Verfahrensschritt des erfindungsgemäßen Verfahrens die dritte Information von der ersten Information und/ oder zweiten Information mindestens teilweise abgestoßen und lagert sich mindestens teilweise außerhalb der ersten Information und/oder zweiten Information an. Gemäß einer zweiten, alternativen erfindungsgemäßen Ausführungsform wird im letzten Verfahrensschritt des erfindungsgemäßen Verfahrens die dritte Information von dem Bereich außerhalb der ersten Information und/oder zweiten Information mindestens teilweise abgestoßen und lagert sich mindestens teilweise innerhalb der ersten Information und/ oder zweiten Information an. Derartige Abstoßungs- und Anlagerungsprozesse sind beispielsweise aus den Druckschriften WO 03/029019 A1 , WO 2009/083146 A2 und WO 2010/057995 A1 bekannt.According to a first embodiment according to the invention, in the last method step of the method according to the invention, the third information is at least partially repelled by the first information and / or second information and is at least partially deposited outside of the first information and / or second information. According to a second, alternative embodiment according to the invention, in the last method step of the method according to the invention, the third information is at least partially repelled from the area outside the first information and / or second information and is at least partially deposited within the first information and / or second information. Such repulsion and attachment processes are, for example, from the publications WO 03/029019 A1 , WO 2009/083146 A2 and WO 2010/057995 A1 known.

Gemäß einer alternativen erfindungsgemäßen Ausführungsform wird im letzten Verfahrensschritt des erfindungsgemäßen Verfahrens die erste Information oder zweite Information in den Bereichen, in denen sie von der dritten Information überdeckt wird, mindestens teilweise von einem Laserstrahl abgetragen. Der von dem Laserstrahl abgetragene Bereich der ersten Information oder zweiten Information trägt hierbei die über ihm angeordnete dritte Information mit ab. Dies bedeutet, dass bei dieser Ausführungsform die erste oder zweite Information laserablatierbar und die dritte Information für den Laserstrahl transparent und nicht laserablatierbar ist. Der Laserstrahl tritt somit durch die dritte Information hindurch und trägt die unter ihr angeordnete erste oder zweite Information ab. Die vom Laserstrahl abgetragenen und beschleunigten Partikel der ersten oder zweiten Information brechen die darüber angeordneten Partikel der dritten Information auf und reißen sie mit, die daneben befindlichen Partikel der dritten Information hingegen werden nicht abgetragen und verbleiben auf dem Substrat.According to an alternative embodiment according to the invention, in the last method step of the method according to the invention, the first information or second information is at least partially removed by a laser beam in the areas in which it is covered by the third information. The area of the first information item or the second information item removed by the laser beam also removes the third information item arranged above it. This means that in this embodiment the first or second information item can be laser ablated and the third item of information is transparent to the laser beam and cannot be laser ablated. The laser beam thus passes through the third information item and removes the first or second information item located below it. The particles of the first or second information item ablated and accelerated by the laser beam break open the particles of the third item of information arranged above and drag them with them, while the particles of the third item of information located next to it are not ablated and remain on the substrate.

Ein Aufdruck auf das Substrat, der erste Information und der zweite Information enthält, erfolgt erfindungsgemäß im Supersimultandruck, bei dem Vorder- und Rückseite gleichzeitig bedruckt werden. Hierbei werden in einem Druckvorgang gleichzeitig die Vorder- und Rückseite des Substrates bedruckt, wodurch ein Passer zwischen den aufgebrachten Druckbildern erzielt wird.An imprint on the substrate containing the first information and the second information is carried out according to the invention using super-simultaneous printing, in which the front and back are printed simultaneously. In this case, the front and back of the substrate are simultaneously printed in one printing process, whereby a register is achieved between the applied print images.

Gemäß einem Ausführungsbeispiel offenbart sich die Passerung für einen Betrachter in Durchsicht. Hierbei ist die Passerung als zwei oder mehr sich ergänzende, komplementierende oder/und überlappende Informationen von Vorder- zu Rückseite zu erkennen. Bevorzugt ergänzen sich dabei in Durchsicht die Informationen auf der Vorder- und der Rückseite zu einer weiteren Information.According to one exemplary embodiment, the registration is revealed to a viewer in see-through. Here, the registration can be recognized as two or more complementary, complementary and / or overlapping pieces of information from front to back. In this case, the information on the front and the back preferably complement each other to form further information.

Gemäß einem weiteren Ausführungsbeispiel ist mindestens eine der Informationen auf dem Wertdokument mittels eines Sensors einer Bearbeitungsmaschine detektierbar. Besonders bevorzugt wird mit diesem Sensor die Passerung der Vorder- zu der Rückseiteninformation geprüft.According to a further exemplary embodiment, at least one of the items of information on the value document can be detected by means of a sensor of a processing machine. This sensor is particularly preferably used to check the registration of the front and back information.

Sowohl für die visuelle als auch für die maschinelle Prüfung des Wertdokuments können die Informationen zusätzliche Merkmale, wie beispielsweise lumineszierende (Fluoreszenz, Phosphoreszenz, Upconversion bzw. Antistokes), IR- oder UV-absorbierende oder emittierende, magnetische, thermochrome oder/und photochrome Zusatzstoffe enthalten.The information can contain additional features, such as luminescent (fluorescence, phosphorescence, upconversion or antistokes), both for the visual and for the machine checking of the document of value. Contain IR or UV absorbing or emitting, magnetic, thermochromic and / or photochromic additives.

Die Benetzungsstörung lässt sich unterteilen in zwei Fälle:

Fall A:
eine Farbabstoßung, die dazu führt, dass es in dem Teilbereich mit farbabstoßender, hydrophober Beschichtung wegen einer höheren Gesamt-Oberflächenspannung zu keiner Farbübertragung mit einer hydrophilen Farbe kommt,
Fall B:
eine Farbabstoßung, die dazu führt, dass es in dem Teilbereich mit der farbabstoßenden, hydrophoben Beschichtung zu einer Entnetzung mit einer nachfolgend aufgetragenen hydrophilen Farbe kommt.
The wetting disturbance can be divided into two cases:
Case A:
color repellency, which means that there is no color transfer with a hydrophilic color in the partial area with the color-repellent, hydrophobic coating due to a higher total surface tension,
Case B:
a color repellency, which leads to a dewetting with a subsequently applied hydrophilic color in the subarea with the color-repellent, hydrophobic coating.

Fall A setzt insbesondere einen Applikationsprozess voraus, der auf einem Spaltprozess beruht. Die Farbe wird entweder direkt von einer planen oder zylindrischen Druckform oder indirekt, beispielsweise mittels Übertragungswalze von der Druckform, auf das Substrat übertragen. Hierbei wird eine Teilschicht auf das Substrat übertragen und verbleibt eine zweite Teilschicht auf der Übertragungswalze oder der Druckform. In dem Teilbereich mit einer farbabstoßenden Beschichtung findet somit keine Farbspaltung statt und die Farbe verbleibt vollständig oder teilweise auf der Übertragungswalze oder der Druckform. Die Adhäsion auf dem Teilbereich der farbabstoßenden Beschichtung muss dabei geringer sein als die Kohäsionskräfte der Farbe oder des Beschichtungsmittels.Case A requires in particular an application process based on a cleavage process. The color is transferred to the substrate either directly from a flat or cylindrical printing form or indirectly, for example by means of a transfer roller from the printing form. Here, a partial layer is transferred to the substrate and a second partial layer remains on the transfer roller or the printing form. In the partial area with an ink-repellent coating, no color splitting takes place and the color remains completely or partially on the transfer roller or the printing form. The adhesion on the partial area of the ink-repellent coating must be less than the cohesive forces of the ink or the coating agent.

Druckprozesse, bei denen die Farbübertragung auf Spaltprozessen beruhen, sind der Offsetdruck, der Hochdruck, der indirekte Hochdruck, der wasserlose Offsetdruck (auch Toray-Verfahren genannt), der Flexodruck und der Tiefdruck.Printing processes in which the color transfer is based on splitting processes are offset printing, letterpress printing, indirect letterpress printing, and waterless Offset printing (also called Toray process), flexographic printing and gravure printing.

Bei dem wasserlosen Offsetdruck liegt die Oberflächenspannung der farbabstoßenden Beschichtung unter 20 mN/m. Die Farbe selbst ist in der Regel hochviskos und mittelkleberig. Der Prozess funktioniert bei hohen Druckgeschwindigkeiten und einem Schichtdickenbereich (bezogen auf die auf das Substrat übertragene Farbe) bis 2 µm. Bei höheren Schichtdicken kann es zum Tonen kommen.In waterless offset printing, the surface tension of the ink-repellent coating is below 20 mN / m. The paint itself is usually highly viscous and medium-adhesive. The process works at high printing speeds and a layer thickness range (based on the color transferred to the substrate) of up to 2 µm. If the layer is thicker, it can lead to toning.

Der Fall B trifft auf alle nicht auf einem Spaltprozess beruhenden Applikationsverfahren zu. Dazu gehören der Ink-Jet-Druck und Siebdruck. Die Farbe wird in beiden Fällen immer komplett auf das Substrat übertragen, unabhängig von der Substratqualität.Case B applies to all application methods that are not based on a cleavage process. These include ink-jet printing and screen printing. In both cases, the color is always completely transferred to the substrate, regardless of the substrate quality.

In Abhängigkeit der Oberflächenspannung des Substrates, der Oberflächenspannung der übertragenen Farbe oder des Beschichtungsmittels, der Rheologie, der physikalischen Trocknung, der Saugfähigkeit der Substrates, der Glätte der Substrate (je glatter desto besser) und der Trocknungszeit, kommt es zu einer mehr oder weniger deutlich sichtbaren Entnetzung der übertragenen Farbe bzw. des Beschichtungsmittels vom Substrat im Bereich der farbabstoßenden Beschichtung. Die Farbe zieht sich dabei zu einer Vielzahl an Tropfen zusammen und/ oder bildet netzförmige Strukturen aus. Beispielsweise ergeben sich bei einer Trocknung der Siebdruckfarbe innerhalb weniger Sekunden nach der Applikation wenige Fehlstellen, beispielsweise ca. 13 % unbenetzte bzw. entnetzte Fehlstellen. Eine Trocknung der Siebdruckfarbe nach 4 Minuten nach der Applikation führt zur Ausbildung netzartiger Strukturen der Siebdruckfarbe mit wenigen Fehlstellen. Eine Trocknung der Siebdruckfarbe nach 10 Minuten nach Applikation führt zu Ausbildung von tropfenartigen Strukturen mit ca. 75 % entnetzten Fehlstellen.Depending on the surface tension of the substrate, the surface tension of the transferred color or the coating agent, the rheology, the physical drying, the absorbency of the substrate, the smoothness of the substrates (the smoother the better) and the drying time, there is a more or less obvious visible dewetting of the transferred ink or of the coating agent from the substrate in the area of the ink-repellent coating. The color contracts to form a large number of drops and / or forms network-like structures. For example, when the screen printing ink dries, there are few imperfections within a few seconds after application, for example approx. 13% non-wetted or drained imperfections. A drying of the screen printing ink after 4 minutes after application leads to the formation of network-like structures of the screen printing ink with few defects. A drying of the screen printing ink after 10 minutes after application leads to Formation of drop-like structures with approx. 75% drained voids.

Der Fall B kann auch bei Druckprozessen auftreten, welche auf einem Spaltprozess beruhen und bei denen niedrig viskose Farben eingesetzt werden. Dies ist beispielsweise bei Siebdruck, Flexodruck und Tiefdruck der Fall. In diesen Fällen kann auch eine Kombination aus Fall A und B auftreten.Case B can also occur in printing processes which are based on a split process and in which low-viscosity inks are used. This is the case, for example, with screen printing, flexographic printing and gravure printing. In these cases, a combination of case A and B can also occur.

Im Fall B bzw. der Kombination aus A und B ist es vorteilhaft, die farbabstoßende Beschichtung in kleinen Strukturen zu drucken, beispielsweise in einem Raster angeordnete Punkte oder Linien, da hierbei die Entnetzung kontrolliert motivbezogen funktioniert.In case B or the combination of A and B, it is advantageous to print the ink-repellent coating in small structures, for example dots or lines arranged in a grid, since the dewetting works in a controlled, motif-related manner.

Besonders bevorzugt ist die Differenz zwischen der Oberflächenspannung der farbabstoßenden hydrophoben und der hydrophilen Farbe möglichst groß. Je geringer hierbei die Schichtdicke ist, desto zuverlässiger erfolgt der farbstoßende Effekt.The difference between the surface tension of the ink-repellent hydrophobic and the hydrophilic ink is particularly preferably as great as possible. The thinner the layer thickness, the more reliable the color-repelling effect will be.

Die Hydrophobierung einer bestehenden oxidativ trocknenden Offsetfarbe kann beispielsweise mit einem Zusatz aus einer 1 %igen bis 3 %igen Emulsion eines hochmolekularen Polydimethylsiloxans oder Lösung eines aminofunktionellen Polysiloxans erfolgen. Als Beispiel für kommerzielle erhältliche Hydrophobierungszusätze, die zur Beimischung in einer Offsetfarbe geeignet sind, sind Tego Glide 482 und Phobe 1500N von der Fa. Evonik zu nennen.An existing, oxidatively drying offset ink can be made hydrophobic, for example, with an additive of a 1% to 3% emulsion of a high molecular weight polydimethylsiloxane or a solution of an amino-functional polysiloxane. Tego Glide 482 and Phobe 1500N from Evonik are examples of commercially available water repellant additives that are suitable for admixture in an offset ink.

Alternativ kann auch eine Farbe bestehend aus einem UV-vernetzenden Silicon oder einem UV-vernetzenden Silicon und/ oder einem UV-vernetzenden Fluoropolymer eingesetzt werden. Insbesondere die Verwendung eines UV-vernetzenden Fluoropolymers erlaubt nochmals eine deutliche Reduzierung der Oberflächenspannung.Alternatively, an ink consisting of a UV-crosslinking silicone or a UV-crosslinking silicone and / or a UV-crosslinking fluoropolymer can be used. In particular, the use of a UV-crosslinking fluoropolymer allows a further significant reduction in surface tension.

Auch eine Kombination der farbabstoßenden Schicht mit einer darauf optimierten Zifferndruckfarbe und/oder Phosphorblock ist möglich. Beide Drucke erfolgen in der Regel als abschließender Druckschritt, so dass sich eine perfekte Passerung ergibt. Bei einem Zifferndruck eignet sich beispielsweise ein Linienuntergrunddruck, so dass die Ziffer nicht zu stark segmentiert wird und damit die Lesbarkeit nicht zu stark eingeschränkt wird.A combination of the ink-repellent layer with a digit printing ink and / or phosphor block optimized thereon is also possible. Both prints are usually carried out as the final printing step, so that a perfect registration results. When printing numbers, for example, a line background print is suitable so that the number is not segmented too much and thus the legibility is not restricted too much.

Gemäß einem Ausführungsbeispiel enthält die farbabstoßende Schicht Substanzen, die nach einer Aktivierung, beispielsweise mittels Heißluft, durch die Druckfarbe hindurch an die Oberfläche migrieren und/ oder verdampfen und somit die Benetzung bzw. Farbannahme einer zweiten Schicht beeinträchtigen. Vorteil dieser Methode ist, dass die oberflächenaktiven Substanzen direkt vor dem zweiten Druckschritt aufgetragen werden können oder bei der Härtung dieser Schicht verwendet werden können. Eine solche entweichende Flüssigkeit ist bevorzugt eine hydrophobe Flüssigkeit, wie ein Mineralöl. Der Siedebereich dieses Mineralöls liegt bevorzugt zwischen 180°C bis 350°C.According to one embodiment, the ink-repellent layer contains substances which, after activation, for example by means of hot air, migrate through the printing ink to the surface and / or evaporate and thus impair the wetting or ink acceptance of a second layer. The advantage of this method is that the surface-active substances can be applied directly before the second printing step or can be used when this layer is hardened. Such a leaking liquid is preferably a hydrophobic liquid such as a mineral oil. The boiling range of this mineral oil is preferably between 180 ° C and 350 ° C.

Fig. 1 zeigt in Fig. 1a in Seitenansicht ein Wertdokument 1, beispielsweise eine Banknote, mit einem Substrat 2 mit einer Vorderseite 3 und einer Rückseite 4. Auf die Vorderseite 3 wird in einem ersten Verfahrensschritt eine erste Information 5 und auf die Rückseite 4 eine zweite Information 6 aufgebracht. Die beiden Informationen 5 und 6 bestehen jeweils aus einer aufgedruckten Offsetfarbe, die visuell nicht oder nur gering erkennbar ist und das Substrat 2 an dieser Stelle stark hydrophobiert. Die Offsetfarben der beiden Informationen 5 und 6 werden jeweils in der geometrischen Form zweier Rechtecke 5.1 und 5.2 bzw. 6.1 und 6.2 auf das Substrat 2 aufgebracht, wie sie in Aufsicht in Fig. 1b von der Vorderseite und in Fig. 1c von der Rückseite mit weiß gestrichelten Linien dargestellt sind. Fig. 1 shows in Fig. 1a a side view of a value document 1, for example a bank note, with a substrate 2 with a front side 3 and a back side 4. In a first method step, a first information item 5 is applied to the front side 3 and a second item of information 6 is applied to the rear side 4. The two pieces of information 5 and 6 each consist of a printed offset ink which is not or only slightly recognizable visually and which makes the substrate 2 highly hydrophobic at this point. The offset colors of the two items of information 5 and 6 are each applied to the substrate 2 in the geometric shape of two rectangles 5.1 and 5.2 or 6.1 and 6.2, as shown in plan view in FIG Figure 1b from the front and in Figure 1c are shown from the rear with white dashed lines.

Anschließend wird in einem zweiten Verfahrensschritt auf die Vorderseite 3 die dritte Information 7 und in einem dritten Verfahrensschritt auf die Rückseite 4 die dritte Information 8 aufgebracht. Die beiden dritten Informationen 7 und 8 werden jeweils in der geometrischen Form eines Rechtecks auf das Substrat 2 aufgebracht und überdecken die beiden Informationen 5 und 6 jeweils mindestens teilweise, wie in Aufsicht in Fig. 1b von der Vorderseite und in Fig. 1c von der Rückseite dargestellt.Subsequently, in a second method step, the third information item 7 is applied to the front side 3 and, in a third method step, the third information item 8 is applied to the rear side 4. The two third pieces of information 7 and 8 are each applied to the substrate 2 in the geometric shape of a rectangle and each at least partially cover the two pieces of information 5 and 6, as in plan view in FIG Figure 1b from the front and in Figure 1c shown from the back.

Die beiden dritten Informationen 7 und 8 bestehen jeweils aus einer deckenden Effektfarbe, die von der hydrophoben Oberfläche der Informationen 5 und 6 abgestoßen werden, so dass die Teile der deckenden Effektfarbe, die im ersten Verfahrensschritt auch auf den Informationen 5 und 6 aufgedruckt wurden von diesen abgestoßen werden und sich außerhalb der ersten 5 und zweiten Information 6 anlagern. Das ursprünglich rechteckförmige Muster der beiden dritten Informationen 7 und 8 ändert sich somit in das in Fig. 1b bzw. Fig. 1c dargestellte Muster.The two third information 7 and 8 each consist of an opaque effect color, which is repelled by the hydrophobic surface of the information 5 and 6, so that the parts of the opaque effect color, the In the first step of the process, the information 5 and 6 were also printed on by these and are deposited outside the first 5 and second information 6. The originally rectangular pattern of the two third pieces of information 7 and 8 thus changes to that in FIG Figure 1b or. Figure 1c illustrated pattern.

In einer weiteren Ausführungsform werden die Effektfarben im Bereich 5 und 6 derart abgestoßen, dass es nur zu einer Fläche mit einer unregelmäßigen Anzahl von Tröpfchenbildung in diesem Bereich kommt.In a further embodiment, the effect colors in areas 5 and 6 are repelled in such a way that there is only one area with an irregular number of droplet formation in this area.

Die zweite Information 6 ist erfindungsgemäß im Passer zur ersten Information 5 aufgebracht, wobei die beiden Rechtecke 5.1 und 6.1 so angeordnet sind, dass sie sich in Durchsicht zu einem durchgehenden Rechteck ergänzen und an den aneinandergrenzenden Enden überlappen. Die beiden Rechtecke 5.2 und 6.2 sind so angeordnet, dass sich in Durchsicht zu einem unterbrochenen Rechteck ergänzen, wobei ihre inneren Enden einen gewissen Überlapp zueinander aufweisen.According to the invention, the second information 6 is applied in register with the first information 5, the two rectangles 5.1 and 6.1 being arranged in such a way that, when viewed through, they complement each other to form a continuous rectangle and overlap at the adjacent ends. The two rectangles 5.2 and 6.2 are arranged in such a way that, when viewed through, they complement one another to form an interrupted rectangle, their inner ends having a certain overlap with one another.

Die im zweiten und dritten Verfahrensschritt aufgedruckten dritten Informationen 7 und 8 sind nicht passerhaltig zueinander und auch nicht passerhaltig zur ersten und zweiten Information 5 und 6 angeordnet, können also in ihrer Position zueinander und zur ersten und zweiten Information 5 und 6 von Banknote zu Banknote abweichen. Die Bereiche, in denen sie von den Rechtecken 5.1, 5.2, 6.1 und 6.2 abgestoßen werden, sind jedoch quasi "automatisch" im Passer zueinander angeordnet, da die Rechtecke 5.1, 5.2, 6.1 und 6.2 zueinander im Passer angeordnet sind.The third information 7 and 8 printed in the second and third process step are not in register with one another and also not with register with the first and second information 5 and 6, so their position with one another and with the first and second information 5 and 6 can differ from banknote to banknote . The areas in which they are repelled by the rectangles 5.1, 5.2, 6.1 and 6.2 are, however, arranged quasi "automatically" in the register, since the rectangles 5.1, 5.2, 6.1 and 6.2 are arranged in relation to one another in the register.

In Durchsicht ergibt sich somit für einen Betrachter das in Fig. 1d dargestellte Bild aus einem dunklen bzw. schwarzen Rechteck, das durch die Überlagerung aus den beiden deckenden Effektfarben der Vorder- und Rückseite gebildet wird, die insgesamt opak sind und durch die Licht somit kaum bzw. nicht hindurchtreten kann. Das dunkle Rechteck ist im oberen Bereich unterbrochen durch einen grauen, einen hellen und einen grauen rechteckförmigen Bereich, die durch die Überlagerung der beiden Rechtecke 5.1 und 6.1 gebildet werden, und im unteren Bereich durch zwei aneinandergrenzende graue rechteckförmige Bereiche, die durch die Rechtecke 5.2 und 6.2 gebildet werden.When looking through, the in Fig. 1d The image shown consists of a dark or black rectangle, which is created by the superimposition of the two opaque effect colors on the front and back which are overall opaque and through which light can hardly or not pass through. The dark rectangle is interrupted in the upper area by a gray, a light and a gray rectangular area, which are formed by the superposition of the two rectangles 5.1 and 6.1, and in the lower area by two adjacent gray rectangular areas, which are defined by the rectangles 5.2 and 6.2 are formed.

Der helle Bereich ergibt sich durch die Überlappung der beiden Rechtecke 5.1 und 6.1, da sich hier sowohl auf der Vorder- als auch auf der Rückseite keine Beschichtung durch die Information 7 und 8 befindet. In diesem Bereich ist auf der Vorder- und Rückseite die Oberfläche des Substrats zu sehen und hat das Wertdokument 1 damit die gleiche oder nahezu gleiche Transluzenz wie das Substrat 2.The light area results from the overlap of the two rectangles 5.1 and 6.1, since there is no coating by the information 7 and 8 on either the front or the rear. In this area, the surface of the substrate can be seen on the front and back and the value document 1 thus has the same or almost the same translucency as the substrate 2.

In den grauen Bereichen befindet sich jeweils nur auf der Vorder- oder Rückseite die Beschichtung durch die Information 7 oder die Information 8. Damit ist hier in Durchlicht nur eine der deckenden Effektfarben zu sehen, so dass ein gewisser Anteil des Lichtes durch das Wertdokument 1 hindurchtreten kann.In the gray areas, the coating by the information 7 or the information 8 is only located on the front or back. Thus, only one of the opaque effect colors can be seen here in transmitted light, so that a certain proportion of the light penetrates through the value document 1 can.

Das in Fig. 2 gezeigte Ausführungsbeispiel entspricht dem in Fig. 1 gezeigten Ausführungsbeispiel, wobei hier auf die Vorderseite 3 des Substrats 2 die erste Information 9 nicht als hydrophobe Beschichtung, sondern als mittels Laser abtragbare Farbe aufgedruckt wird.This in Fig. 2 The embodiment shown corresponds to that in Fig. 1 embodiment shown, wherein the first information 9 is not printed on the front side 3 of the substrate 2 as a hydrophobic coating, but as an ink that can be removed by means of a laser.

Die erste Information 9 wird hierbei im Passer zur zweiten Information 6 und in Form von zwei Rechtecken auf das Substrat 2 aufgedruckt, die in Form und Position den Rechtecken 5.1 und 5.2 aus Fig. 1 entsprechen.The first information 9 is in this case printed in register with the second information 6 and in the form of two rectangles on the substrate 2, the form and position of which correspond to the rectangles 5.1 and 5.2 Fig. 1 correspond.

Anschließend wird die dritte Information 7 in Form eines Rechtecks, das dem Rechteck aus Fig. 1 entspricht, über die erste Information 9 gedruckt, wie in Fig. 2b dargestellt. Die Effektfarbe der dritten Information 7 ist hierbei für die Wellenlänge der Laserstrahlung, für die die erste Information 9 empfindlich ist, transparent.The third information 7 is then in the form of a rectangle, which is made up of the rectangle Fig. 1 is printed over the first information 9 as shown in FIG Figure 2b shown. The effect color of the third information 7 is transparent for the wavelength of the laser radiation to which the first information 9 is sensitive.

Bei einer Beaufschlagung der Vorderseite mit Laserstrahlung wird somit die erste Information abgetragen. In den Bereichen, in denen die dritte Information 7 die erste Information 9 überlappt, tritt der Laserstrahl durch die dritte Information 7 hindurch, ohne sie zunächst zu beeinflussen, trifft dann auf die erste Information 9 und trägt diese ab. Das abgetragene Material der ersten Information 9 reißt die über ihr liegenden Teile der dritten Information 7 mit weg, so dass die dritte Information 7 die in Fig. 2c gezeigte geometrische Form annimmt.When laser radiation is applied to the front side, the first information is removed. In the areas in which the third information 7 overlaps the first information 9, the laser beam passes through the third information 7 without initially influencing it, then hits the first information 9 and removes it. The removed material of the first information 9 tears away the parts of the third information 7 lying above it, so that the third information 7 corresponds to the in Figure 2c shown geometric shape assumes.

Somit ergibt sich für einen Betrachter in Durchsicht ein Bild, wie es in Fig. 2e zu sehen ist und dem aus Fig. 1d entspricht.Thus, for a viewer looking through, there is an image as it is in Fig. 2e can be seen and that from Fig. 1d corresponds to.

Bei dem in Fig. 3 gezeigten Ausführungsbeispiel entspricht lediglich der Aufbau auf der Rückseite 4 des Substrats 2 dem Aufbau aus Fig. 1. Auf die Vorderseite wird eine erste Information 10 im Passer zur zweiten Information aufgedruckt, die aus einer visuell erkennbaren Offsetfarbe besteht. Die Information 10 weist bereits die geometrische Form auf, die in Fig. 3b dargestellt ist und die derjenigen aus Fig. 1b entspricht.The in Fig. 3 The embodiment shown corresponds only to the structure on the rear side 4 of the substrate 2 from the structure Fig. 1 . A first piece of information 10 is printed on the front side in register with the second piece of information, which consists of a visually recognizable offset color. The information 10 already has the geometric shape shown in FIG Figure 3b is shown and that of those from Figure 1b corresponds to.

Somit ergibt sich für einen Betrachter in Durchsicht ein Bild, wie es in Fig. 3d zu sehen ist und demjenigen aus Fig. 1d entspricht.Thus, for a viewer looking through, there is an image as it is in Fig. 3d can be seen and the one from Fig. 1d corresponds to.

Selbstverständlich können alle der oben genannten Ausführungsformen der Fig. 1 bis 3 und alle Ausführungsbeispiele miteinander kombiniert werden, wobei eine Ausführungsform auf der Vorderseite mit jeder beliebigen Ausführungsform auf der Rückseite kombiniert wird, soweit dies vom Schutzbereich der Ansprüche abgedeckt ist.Of course, all of the above-mentioned embodiments of the Figs. 1 to 3 and all exemplary embodiments are combined with one another, one embodiment on the front side being combined with any desired embodiment on the rear side, insofar as this is covered by the scope of protection of the claims.
