Description

Die Erfindung betrifft ein Prägewerkzeug zur Herstellung eines Sicherheitselements mit einer optisch variablen Struktur, wobei die optisch variable Struktur beim Kippen des Sicherheitselementes um eine Achse einen Kippeffekt zeigt. Das Prägewerkzeug besteht hierbei aus einer Prägeplatte mit einer Oberfläche, wobei die Oberfläche der Prägeplatte eine Vielzahl von im Wesentlichen parallel zueinander angeordneten, rinnenförmigen Vertiefungen aufweist. Diese rinnenförmigen Vertiefungen bestehen jeweils aus einer ersten und einer zweiten Flanke, die sich gegenüberliegen, wobei jeweils die erste Flanke einer Vertiefung und die zweite Flanke der dieser Vertiefung benachbarten Vertiefung in Richtung der Oberfläche der Prägeplatte aufeinander zulaufen. Des Weiteren ist jeweils zwischen der ersten Flanke einer Vertiefung und der zweiten Flanke der dieser Vertiefung benachbarten Vertiefung ein ebener Bereich angeordnet, der im Wesentlichen parallel zur Oberfläche der Prägeplatte ausgerichtet ist.The invention relates to an embossing tool for producing a security element with an optically variable structure, the optically variable structure showing a tilting effect when the security element is tilted about an axis. The embossing tool here consists of an embossing plate with a surface, the surface of the embossing plate having a multiplicity of channel-shaped depressions arranged essentially parallel to one another. These channel-shaped depressions each consist of a first and a second flank, which lie opposite one another, the first flank of a depression and the second flank of the depression adjacent to this depression converging towards one another in the direction of the surface of the embossing plate. Furthermore, a flat area is arranged between the first flank of a depression and the second flank of the depression adjacent to this depression, which is aligned essentially parallel to the surface of the embossing plate.

Zum Schutz gegen Nachahmung, insbesondere mit Farbkopierern oder anderen Reproduktionsverfahren, werden Datenträger, wie beispielsweise Banknoten, Wertpapiere, Kredit- oder Ausweiskarten, Pässe, Urkunden und Ähnliches, Labels, Verpackungen oder andere Elemente für die Produktsicherung mit optisch variablen Sicherheitselementen ausgestattet. Der Fälschungsschutz beruht dabei darauf, dass der visuell und einfach und deutlich erkennbare optisch variable Effekt von den oben genannten Reproduktionsgeräten nicht oder nur ungenügend wiedergegeben wird. Insbesondere weisen die optisch variablen Sicherheitselemente eine entsprechende Haptik auf, die schwer zu kopieren, aber leicht und ohne Hilfsmittel zu überprüfen ist.To protect against counterfeiting, especially with color copiers or other reproduction methods, data carriers such as banknotes, securities, credit or identification cards, passports, certificates and the like, labels, packaging or other elements for product security are equipped with optically variable security elements. The protection against counterfeiting is based on the fact that the visually and easily and clearly recognizable optically variable effect is not or only insufficiently reproduced by the above-mentioned reproduction devices. In particular, the optically variable security elements have a corresponding haptic that is difficult to copy, but easy to check and without tools.

Ein derartiges optisch variables Sicherheitselement, das beim Kippen des Sicherheitselementes um eine Achse einen Kippeffekt zeigt, ist beispielsweise aus WO 2013/045055 A1 bekannt. Hierbei ist ein Sicherheitselement mit einer optisch variablen Struktur bekannt, die eine Vielzahl von ersten Prägestrukturen aufweist. Jede der ersten Prägestrukturen besteht aus mindestens zwei Flanken, die in mindestens einem bestimmten Winkel aufeinander zulaufen. Die WO 2013/045055 A1 betrifft weiterhin ein Prägewerkzeug zur Herstellung dieses Sicherheitselements. Hierbei weist eine Prägeplatte Vertiefungen auf, mit denen prismen- oder pyramidenförmige Prägestrukturen erzeugt werden. Ein Substrat wird auf die Oberfläche der Prägeplatte aufgelegt, mit hohem mechanischem Druck in die Vertiefungen gepresst und verformt. Vorteilhaft weist die Grundprägelinie der Prägeplatte eine gerade Oberkante auf, welche stabil der Laserung standhält und stets "unverletzt" gleichbleibend ist.Such an optically variable security element, which shows a tilting effect when the security element is tilted about an axis, is, for example, out of WO 2013/045055 A1 known. Here, a security element with an optically variable structure is known, which has a plurality of first embossed structures. Each of the first embossed structures consists of at least two flanks that converge at least at a certain angle. The WO 2013/045055 A1 also relates to an embossing tool for producing this security element. Here, an embossing plate has depressions with which prism or pyramid-shaped embossing structures are produced. A substrate is placed on the surface of the embossing plate, pressed into the depressions with high mechanical pressure and deformed. The basic embossing line of the embossing plate advantageously has a straight upper edge, which stands up to the lasering and is always "undamaged" constant.

Nachteilig an der Grundform der prismen- oder pyramidenförmigen Prägestrukturen aus WO 2013/045055 A1 ist jedoch, dass sie in ihrer Grundform aus allen Betrachtungsrichtungen den gleichen Kippeffekt zeigen. Zur Lösung dieses Nachteils schlägt die WO 2013/045055 A1 vor, dass in mindestens einem Teilbereich der optisch variablen Struktur mindestens eine Flanke der ersten Prägestrukturen jeweils mindestens eine zusätzliche Prägestruktur aufweist, die auf die Flanke der ersten Prägestrukturen aufgesetzt oder in die Flanke der ersten Prägestrukturen eingesetzt ist. Eine derartige Prägestruktur setzt jedoch einen erhöhten technischen Aufwand bei der Gravur der entsprechenden Prägeplatte voraus.A disadvantage of the basic shape of the prismatic or pyramidal embossed structures WO 2013/045055 A1 is, however, that their basic form shows the same tipping effect from all viewing directions. To solve this disadvantage, the WO 2013/045055 A1 proposes that in at least one partial area of the optically variable structure at least one flank of the first embossed structures each has at least one additional embossed structure which is placed on the flank of the first embossed structures or inserted into the flank of the first embossed structures. Such an embossing structure, however, requires an increased technical outlay when engraving the corresponding embossing plate.

Aus WO 00/20217 A1 ist eine Stichtiefdruckplatte zum vollflächigen Drucken zusammenhängender Druckbildbereiche bekannt, bei der das Druckbild in Form einer Gravur in die Druckplattenoberfläche eingearbeitet ist. Hierbei sind in den gravierten, farbaufnehmenden Bereichen Trennstege vorgesehen, welche die gravierten Bereiche in Teilbereiche aufteilen, wobei die Trennstege derart gestaltet sind, dass sie keine Flächen in Höhe der Druckplattenoberfläche aufweisen. Zusätzlich können die nach außen zeigenden Enden der Trennstege nach Gravur der die Feinstruktur bildenden Vertiefungen entfernt werden. Diese als Plateau ausgebildeten oberen Enden der Trennstege erzeugen im Druckbild feine helle Linien.Out WO 00/20217 A1 a intaglio printing plate for full-surface printing of contiguous print image areas is known, in which the print image is worked into the surface of the printing plate in the form of an engraving. Here, dividers are provided in the engraved, ink-receiving areas, which divide the engraved areas into partial areas, the dividers being designed in such a way that they have no surfaces at the level of the printing plate surface. In addition, the ends of the separating webs pointing outwards can be removed after the recesses forming the fine structure have been engraved. These upper ends of the dividers, which are designed as a plateau, produce fine bright lines in the printed image.

Mit der Stichtiefdruckplatte aus WO 00/20217 A1 werden jedoch keine Prägestrukturen erzeugt, die einen vom Betrachtungswinkel abhängigen Kippeffekt zeigen. Selbst, wenn diese Prägestrukturen einen Kippeffekt zeigen würden, würden sie aus allen Betrachtungsrichtungen den gleichen Kippeffekt zeigen.With the intaglio printing plate WO 00/20217 A1 However, no embossed structures are produced that show a tilting effect that depends on the viewing angle. Even if these embossed structures showed a tilting effect, they would show the same tilting effect from all viewing directions.

Aus EP 0 429 782 A1 ist eine beugungsoptisch wirksame Beugungsstruktur bekannt, die jeweils aus einer beugungsoptisch wirksamen Mikrostruktur bestehen, wobei die Mikrostrukturen annähernd 300 bis 3000 Linien pro Millimeter beziehungsweise eine Linienbreite von 300 nm bis 3 µm aufweisen.Out EP 0 429 782 A1 a diffraction-optically effective diffraction structure is known, each consisting of a diffraction-optically effective microstructure, the microstructures having approximately 300 to 3000 lines per millimeter or a line width of 300 nm to 3 μm.

Aus EP 2 886 356 A2 ist eine feine Struktur bekannt, die innerhalb einer makroskopischen Prägestruktur angeordnet ist. Diese feine Struktur weist eine Tiefe von 0,1 µm bis 10 µm auf und ist beispielsweise eine Beugungsstruktur. Die makroskopische Prägestruktur hingegen weist eine Tiefe in einem Bereich von 13 µm bis 30 µm auf.Out EP 2 886 356 A2 a fine structure is known which is arranged within a macroscopic embossed structure. This fine structure has a depth of 0.1 µm to 10 µm and is, for example, a diffraction structure. The macroscopic embossed structure, on the other hand, has a depth in a range from 13 µm to 30 µm.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein gattungsgemäßes Prägewerkzeug derart weiterzubilden, dass die Nachteile des Standes der Technik behoben werden.The invention is therefore based on the object of developing a generic embossing tool in such a way that the disadvantages of the prior art are eliminated.

Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by the features of independent claim 1. Further developments of the invention are the subject of the dependent claims.

Erfindungsgemäß weist die erste Flanke jeder rinnenförmigen Vertiefung einen anderen Neigungswinkel gegenüber der Oberfläche der Prägeplatte auf als die entsprechende zweite, gegenüberliegende Flanke. Die erste Flanke ist hierbei bevorzugt steiler als die zweite Flanke. Der Neigungswinkel der ersten Flanke beträgt bevorzugt 0° bis 40°, besonders bevorzugt 10° bis 30° und ganz besonders bevorzugt 20° bis 30° gegenüber der Flächennormalen der Oberfläche der Prägeplatte oder der Senkrechten auf der Oberfläche der Prägeplatte. 0° bedeutet hierbei, dass die Flanke senkrecht zur Oberfläche der Prägeplatte ausgerichtet ist. Die Flanken können auch bogenförmig, gekrümmt und/oder treppenförmig ausgestaltet sein, so dass sich der Neigungswinkel einer Flanke mit zunehmendem Abstand von der Oberfläche der Prägeplatte ändert.According to the invention, the first flank of each groove-shaped depression has a different angle of inclination with respect to the surface of the embossing plate than the corresponding second, opposite flank. The first flank is preferably steeper than the second flank. The angle of inclination of the first flank is preferably 0 ° to 40 °, particularly preferably 10 ° to 30 ° and very particularly preferably 20 ° to 30 ° with respect to the surface normal of the surface of the embossing plate or the perpendicular to the surface of the embossing plate. 0 ° here means that the flank is aligned perpendicular to the surface of the embossing plate. The flanks can also be arc-shaped, curved and / or stair-shaped, so that the angle of inclination of a flank changes with increasing distance from the surface of the embossing plate.

Die erfindungsgemäßen rinnenförmigen Vertiefungen sind somit asymmetrisch ausgeformt, so dass sich bei mit dieser Prägeplatte erzeugten Prägestrukturen ein aus unterschiedlichen Betrachtungsrichtungen unterschiedlicher Kippeffekt ergibt, je nach dem, auf welche der beiden Flanken der Betrachter blickt.The groove-shaped depressions according to the invention are thus asymmetrically shaped, so that the embossing structures produced with this embossing plate result in a different tilting effect from different viewing directions, depending on which of the two flanks the viewer is looking at.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass das Prägewerkzeug ein Prägestempel oder eine Druckplatte ist, insbesondere eine Stichtiefdruckplatte ist, und die Vertiefungen als Gravur in der Oberfläche des Prägewerkzeuges ausgeführt sind.According to a preferred embodiment, it is provided that the embossing tool is an embossing stamp or a printing plate, in particular an intaglio printing plate, and the depressions are designed as an engraving in the surface of the embossing tool.

Zusätzlich wird durch den ebenen Bereich, der jeweils zwischen der ersten Flanke einer Vertiefung und der zweiten Flanke der dieser Vertiefung benachbarten Vertiefung angeordnet und im Wesentlichen parallel zur Oberfläche der Prägeplatte ausgerichtet ist, ein Plateau gebildet. Dieses Plateau hat gegenüber spitzen Strukturen den Vorteil, dass es unempfindlicher gegen Erosion durch Bearbeitungswerkzeuge ist, mit denen das Prägewerkzeug graviert wird, insbesondere einen (breiten) Laserstrahl. Des Weiteren sind Plateaus unempfindlicher bei Entgratung, Reinigung und Polieren des Prägewerkzeugs, beispielsweise mittels Rakel, Poliermittel, Schleifmittel, Ätzverfahren oder mittels rotierender Bürsten und weisen somit einen geringeren Plattenverschleiß auf. Des Weiteren hat eine nachgelagerte Verchromung des Prägewerkzeugs eine bessere Haftung auf dem Trägermaterial, wodurch sich der mechanische Verschleiß zusätzlich reduziert.In addition, a plateau is formed by the flat region, which is arranged between the first flank of a depression and the second flank of the depression adjacent to this depression and is oriented essentially parallel to the surface of the embossing plate. This plateau has the advantage over pointed structures that it is less sensitive to erosion by processing tools with which the embossing tool is engraved, in particular a (wide) laser beam. Furthermore, plateaus are less sensitive to deburring, cleaning and polishing the embossing tool, for example by means of a doctor blade, polishing agent, abrasive, etching process or by means of rotating brushes, and thus have less plate wear. Furthermore, subsequent chrome plating of the embossing tool has better adhesion to the carrier material, which further reduces mechanical wear.

Im Wesentlichen parallel bedeutet hierbei, dass der Winkel zwischen der Vertiefung oder dem Plateau und der Oberfläche der Prägeplatte bzw. den rinnenförmigen Vertiefungen zueinander bevorzugt 0° (exakt parallel) und besonders bevorzugt 0,5° bis 5° beträgt.In this context, essentially parallel means that the angle between the depression or the plateau and the surface of the embossing plate or the groove-shaped depressions relative to one another is preferably 0 ° (exactly parallel) and particularly preferably 0.5 ° to 5 °.

Besondere Vorteile des erfindungsgemäßen Prägewerkzeugs sind weiterhin, dass das Plateau zu einer Reduzierung der Kantenschärfe führt, so dass während der Prägung einer möglichen Papierverletzung vorgebeugt und die Haltbarkeit des Wischzylinders einer Stichtiefduckmaschine erhöht werden kann. Umgekehrt sind die Plateaus auch unempfindlicher gegen Abnutzung durch den Wischzylinder.Special advantages of the embossing tool according to the invention are furthermore that the plateau leads to a reduction in the sharpness of the edges, so that a possible paper injury can be prevented during embossing and the durability of the wiping cylinder of a low-pressure printing machine can be increased. Conversely, the plateaus are also less sensitive to wear from the wiping cylinder.

Das erfindungsgemäße Prägewerkzeug eignet sich besonders bevorzugt bei Gravurverfahren, bei denen mittels Laserstrahl in ein rotierendes zylindrisches Werkstück aus Kunststoff, beispielsweise Kapton, oder aus Metall, beispielsweise Messing, graviert wird, das sogenannte "Computer to Intaglioplate"- bzw. "CTiP"-Verfahren. Dabei ist es durch die Erfindung bevorzugt möglich, CTiP-Anlagen zum Einsatz kommen zu lassen und so die Verwendung von "Daten-Handelsware" zu ermöglichen, also vorgegebenen Prägedaten für bestimmte Banknoten-Nennwerte einer Währung. Auch bei fehlender Kompensation des Laserdurchmessers, kann durch geeignete Wahl der Plateaus eine Verletzung der gewünschten Prägestrukturen vermieden werden, indem innerhalb der Datenstruktur ausreichend breite Plateaus vorgehalten werden.The embossing tool according to the invention is particularly preferably suitable for engraving processes in which a laser beam is used to rotate into a rotating cylindrical workpiece made of plastic, for example Kapton, or of metal, for example Brass, is engraved, the so-called "Computer to Intaglioplate" or "CTiP" process. The invention preferably makes it possible to use CTiP systems and thus to enable the use of “data commercial goods”, that is to say predetermined embossed data for certain denominations of a currency's denominations. Even if the laser diameter is not compensated for, a suitable choice of the plateaus prevents damage to the desired embossed structures by providing sufficiently broad plateaus within the data structure.

Des Weiteren können nun Systeme mit einer geringeren physikalischen Auflösung ein ansprechendes Ergebnis erzielen.Furthermore, systems with a lower physical resolution can now achieve an appealing result.

Die Erfindung ist jedoch nicht nur auf Prägewerkzeuge beschränkt, die mittels Laserstrahl graviert werden. Vielmehr können auch alle anderen aus dem Stand der Technik bekannten Gravurverfahren verwendet werden, wie beispielsweise mechanische Gravur mittels Stichel.However, the invention is not only limited to embossing tools that are engraved using a laser beam. Rather, all other engraving methods known from the prior art can also be used, such as mechanical engraving using a stylus.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die Querschnittsfläche der im Wesentlichen parallel zueinander angeordneten, rinnenförmigen Vertiefungen dreieckig oder trapezförmig ausgestaltet ist. Beispielsweise ergibt eine dreieckige Querschnittsfläche walmdachartige Prägestrukturen.According to a preferred embodiment, it is provided that the cross-sectional area of the groove-shaped depressions arranged essentially parallel to one another is triangular or trapezoidal. For example, a triangular cross-sectional area results in embossed roof-like structures.

Besonders zweckmäßig ist es darüber hinaus, wenn das Verhältnis aus dem Abstand benachbarter Gravuren und der entsprechenden Gravurtiefe, das sogenannte Aspektverhältnis, 1:5 bis 20:1, bevorzugt 1:3 bis 10:1 und besonders bevorzugt 1:2 bis 6:1 beträgt.It is also particularly expedient if the ratio of the distance between adjacent engravings and the corresponding engraving depth, the so-called aspect ratio, is 1: 5 to 20: 1, preferably 1: 3 to 10: 1 and particularly preferably 1: 2 to 6: 1 is.

Erfindungsgemäß beträgt die Tiefe der im Wesentlichen parallel zueinander angeordneten, rinnenförmigen Vertiefungen 10 µm bis 250 µm, bevorzugt 10 µm bis 100 µm und besonders bevorzugt 10 µm bis 80 µm.According to the invention, the depth of the groove-shaped depressions arranged essentially parallel to one another is 10 μm to 250 μm, preferably 10 μm to 100 μm and particularly preferably 10 μm to 80 μm.

Gemäß einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass mindestens einer der ebenen Bereiche, die zwischen der ersten Flanke einer Vertiefung und der zweiten Flanke der dieser Vertiefung benachbarten Vertiefung angeordnet sind, und die im Wesentlichen parallel zur Oberfläche der Prägeplatte ausgerichtet sind, gegenüber der Oberfläche der Prägeplatte abgesenkt ist.According to a further preferred embodiment, it is provided that at least one of the flat regions which are arranged between the first flank of a depression and the second flank of the depression adjacent to this depression and which are aligned essentially parallel to the surface of the embossing plate, relative to the surface of the Stamping plate is lowered.

Gemäß einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass jeweils zwischen der ersten Flanke einer Vertiefung und der zweiten Flanke dieser Vertiefung ein zweiter ebener Bereich angeordnet ist, der im Wesentlichen parallel zur Oberfläche der Prägeplatte ausgerichtet ist. Hierbei weisen nicht nur die "Gipfel" der Vertiefungen, die der Oberfläche der Prägeplatte zugewandt sind, ein Plateau auf, sondern auch die "Täler", die von der Oberfläche der Prägeplatte abgewandt sind.According to a further preferred embodiment, it is provided that between the first flank of a depression and the second flank of this depression a second flat region is arranged, which is aligned essentially parallel to the surface of the embossing plate. Here, not only do the "peaks" of the depressions which face the surface of the embossing plate have a plateau, but also the "valleys" which face away from the surface of the embossing plate.

Erfindungsgemäß beträgt die Breite eines ebenen Bereichs, d.h. sowohl der "Gipfel" als auch der "Täler", 1 µm bis 100 µm, bevorzugt 5 µm bis 50 µm und besonders bevorzugt 10 µm bis 30 µm.According to the invention, the width of a flat area, i.e. both the "peak" and the "valleys", 1 µm to 100 µm, preferably 5 µm to 50 µm and particularly preferably 10 µm to 30 µm.

Ein optisch variables Element im Sinne dieser Erfindung ist ein Element, dessen visuelles Erscheinungsbild sich bei Verkippen des Elements ändert. Beispielsweise ändert sich bei Verkippen des optisch variablen Elements dessen Farbe, bewegt sich scheinbar ein Balken von einer Seite des Elements zu einer anderen Seite, werden beim Verkippen unterschiedliche Zeichen dargestellt oder ergibt sich ein sogenannter Pumpeffekt in Form einer sich vergrößernden oder verkleinernden Umrisslinie eines Bildmotivs.An optically variable element in the sense of this invention is an element whose visual appearance changes when the element is tilted. For example, when the optically variable element changes its color, a bar appears to move from one side of the element to another, different characters are displayed when the element is tilted, or a so-called pump effect results in the form of an enlarging or reducing outline of an image motif.

Das Substrat, in das die Prägestrukturen eingeprägt werden, besteht besonders bevorzugt aus Papier aus Baumwollfasern, wie es beispielsweise für Banknoten verwendet wird, oder aus anderen natürlichen Fasern oder aus Synthesefasern oder einer Mischung aus natürlichen und synthetischen Fasern, oder aus mindestens einer Kunststofffolie. Weiterhin bevorzugt besteht das Substrat aus einer Kombination aus mindestens zwei übereinander angeordneten und miteinander verbundenen unterschiedlichen Substraten, einem sogenannten Hybrid.
