Abstract
Description
Die Erfindung betrifft ein Sicherheitselement mit einem flächigen Substrat, das in Echtheitszertifikaten oder Wertpapieren eingesetzt werden kann.The Invention relates to a security element with a planar substrate, which are used in certificates of authenticity or securities can.
Bekannte Sicherheitselemente mit einem flächigen Substrat sind Hologramme, Kinegramme und allgemein Wechselbilder. Ihnen ist gemeinsam, daß der wahrgenommene Bildinhalt sich mit einer Veränderung des Betrachtungswinkels signifikant ändert. Die Änderung des Bildinhalts bei wechselndem Betrachtungswinkel ist je nach verwendeter Technik mehr oder weniger stark. Generell wird ein starker optischer Wechseleffekt angestrebt, um die Wahrnehmbarkeit auch unter ungünstigen Bedingungen zu gewährleisten.Known Security elements with a flat Substrate are holograms, kinegrams and generally alternating pictures. They have in common that the perceived image content with a change in the viewing angle changes significantly. The change the picture content with changing viewing angle is depending on the used Technology more or less strong. Generally, a strong optical Interactive effect aimed at the perceptibility even under unfavorable To ensure conditions.
Zu unterscheiden ist allerdings zwischen der optischen Wahrnehmbarkeit und dem dadurch ausgelösten Erkennungseffekt. Auch Sicherheitselemente können gefälscht werden und bei Veränderung des Betrachtungswinkels einen optischen Effekt erzeugen. Aus der Sicht des Verbrauchers ist es kaum möglich, ein solches Sicherheitsmerkmal als Fälschung zu erkennen, wenn nicht der durch wechselnde Betrachtungswinkel erzeugte optische Effekt hochgradig erkennbar, eindeutig und vor allem konsistent ist.To however, there is a difference between visual perceptibility and thereby triggered Recognition. Also security elements can be forged and if changed Viewing angle produce an optical effect. From the From the point of view of the consumer, it is hardly possible to have such a security feature as a fake to recognize if not by changing viewing angles generated optical effect highly recognizable, unique and before everything is consistent.
Diese Forderung läßt sich mit Wechselbildern, z. B. Refraktionsbildern, gut erfüllen, da bei diesen der optische Effekt in einer kompletten Veränderung des Bildinhalts bestehen kann. Eine eindeutige Echtheitsaussage kann darin bestehen, daß bei probeweisem Kippen, Wippen oder Verschwenken eines Echtheitszertifikats die sonst nicht unmittelbar sichtbare Kennzeichnung des genuinen Herstellers augenfällig in Erscheinung tritt. Dieses Beispiel erfüllt auch die Forderung nach Konsistenz, da der Verbraucher so bei unterschiedlichsten Produkten immer nur darauf zu achten hat, daß die vertraute Marke des genuinen Herstellers sichtbar wird.These Demand can be with change pictures, z. As refraction images, well, since in these the optical effect in a complete change of the image content. A clear statement of authenticity may be that at trial tilting, rocking or swinging a certificate of authenticity the otherwise not directly visible marking of genuine Manufacturer obvious appears in appearance. This example also meets the demand for Consistency, as the consumer so with a wide variety of products always have to make sure that the familiar brand of genuine Manufacturer is visible.
Refraktionsbilder bestehen aus einem periodischen Liniemuster, das auf einem Substrat aufgebracht ist, und einer das Linienmuster bedeckenden Linsenstruktur aus zu den Linien des Linsenmusters parallelen Zylinderlinsen. Je nach dem Betrachtungswinkel, unter dem das periodische Linienmuster durch die Linsenstruktur gesehen wird, sind in jeder Periode des Linienmusters verschiedene Linien des Musters sichtbar, die zusammen das wahrgenommene Bild ergeben. Durch die Gestaltung des Linienmusters können diverse optische Effekte erzielt werden, durch die der Betrachter bei verschiedenen Betrachtungswinkeln verschiedene Bildinhalte wahrnimmt. Die Herstellung eines Linsenmusters ist aber aufwendig.refraction images consist of a periodic line pattern on a substrate is applied, and a lens pattern covering the line pattern from to the lines of the lens pattern parallel cylindrical lenses. ever by the viewing angle under which the periodic line pattern passes through The lens structure is seen in each period of the line pattern different lines of the pattern are visible, which together perceive the Picture result. Through the design of the line pattern can diverse optical effects are achieved by which the viewer at different Viewing angles perceives different image content. The production a lens pattern is consuming.
Um die Sicherheitselemente auch bei Massenprodukten anwenden zu können, müssen die zu ihrer Erzeugung anfallenden Kosten gering sein.Around To be able to use the security elements also with mass products, the be low for their production costs.
Durch die Erfindung wird ein Sicherheitselement geschaffen, das einen starken optischen Wechseleffekt, vergleichbar mit Refraktionsbildern, erzeugt und nur mit speziellem Gerät hergestellt werden kann, mit diesem jedoch kostengünstig.By The invention provides a security element is provided, the one strong optical interaction, comparable to refraction images, generated and can only be produced with a special device, but inexpensive with this.
Das erfindungsgemäße Sicherheitselement hat ein flächiges Substrat aus transparentem Material, das auf der einen Fläche ein Maskenmuster aus opaken Strukturen und auf der gegenüberliegenden Fläche ein Bildmuster trägt. Das Maskenmuster und das Bildmuster sind derart aufeinander abgestimmt, daß bei Blick auf die Fläche des Maskenmusters oder des Bildmusters unter verschiedenen Betrachtungswinkeln verschiedene Bereiche des Bildmusters durch das Maskenmuster sichtbar sind. Dabei sind grundsätzlich zwei Lösungswege möglich. Bei dem ersten Lösungsweg befindet sich das Maskenmuster auf der Sichtseite. Je nach Betrachtungswinkel gibt das Maskenmuster verschiedene Bereiche des Bildmusters frei, die einen gemeinsamen Bildinhalt darstellen, und deckt die anderen Bildbereiche ab. Bei dem zweiten Lösungsweg befindet sich das transluzente Bildmuster auf der Sichtseite. Je nach Betrachtungswinkel läßt das Maskenmuster verschiedene Anteile des auf die Rückseite (d. h. die vom Betrachter abgewandte Seite) des Bildmuster fallenden Lichts zu dem transluzenten Bildmuster durchtreten, so daß verschiedene Bereiche des Bildmusters sichtbar sind, die jeweils einen gemeinsamen Bildinhalt darstellen, während das Maskenmuster die anderen Bereiche des Bildmusters gegen das Licht abschirmt.The has security element according to the invention a flat Substrate made of transparent material, which is on one surface Mask pattern of opaque structures and on the opposite surface Wearing pattern. The mask pattern and the image pattern are matched to one another such that when Blick on the surface the mask pattern or the image pattern under different viewing angles different areas of the image pattern visible through the mask pattern are. Here are basically two solutions possible. In the first solution the mask pattern is on the visible side. Depending on the viewing angle the mask pattern releases different areas of the image pattern which represent a common image content, and covers the others Image areas. In the second approach is the translucent image patterns on the visible side. Depending on the viewing angle leaves the mask pattern different proportions of the on the back (ie the viewer opposite side) of the image pattern falling light to the translucent Pass through image patterns, so that different Areas of the image pattern are visible, each having a common Picture content while the mask pattern the other areas of the image pattern against the Light shields.
Das Bildmuster und das Maskenmuster können auf dem Substrat mit drucktechnischen Verfahren aufgebracht werden. Prinzipiell sind drucktechnische Verfahren kostengünstig bei der Herstellung großer Stückzahlen. Allerdings stellt das erfindungsgemäße Sicherheitselement hohe Anforderungen an die gegenseitige Abstimmung von Maskenmuster und Bildmuster, insbesondere hinsichtlich der Maßhaltigkeit der verwendeten Raster. Alle Anforderungen können mit Simultandruck (gleichzeitiges Bedrucken beider Substratflächen in derselben Druckpresse) gut erfüllt werden. Simultandruck ist eine Technik, die hohe Anlageninvestitionen erfordert und dem Fälscher nicht zugänglich ist.The Image patterns and the mask pattern can be printed on the substrate Procedures are applied. In principle, printing processes economical in the production of large Quantities. However, the security element according to the invention is high Requirements for the mutual matching of mask patterns and Patterns, in particular with regard to the dimensional accuracy of the used Grid. All requirements can with simultaneous printing (simultaneous printing of both substrate surfaces in the same printing press) become. Simultaneous pressure is a technique that requires high capital investment requires and the counterfeiter inaccessible is.
Der mit dem Sicherheitselement verbundene optische Wechseleffekt kann darin bestehen, daß sich der wahrgenommene Bildinhalt bei Verschwenkung des Substrate um eine Achse signifikant ändert. Bei der bevorzugten Ausführungsform werden aber verschiedene optische Wechseleffekte erzielt, wenn sich der Betrachtungswinkel in verschiedenen Ebenen ändert. Insbesondere wird ein erster optischer Wechseleffekt durch "Wippen" und ein zweiter optischer Wechseleffekt durch "Kippen", also durch Verschwenken um zwei zueinander senkrechte Achsen, die beide parallel zum Substrat sind, erzielt. Anders ausgedrückt: der Betrachtungswinkel wird in zwei aufeinander senkrechten Ebenen, die beide senkrecht zur Ebenen des Substrats sind, durch "Wippen" und "Kippen" verändert.The optical switching effect associated with the security element may be that the perceived image content changes significantly as the substrate is pivoted about an axis. However, in the preferred embodiment, different optical switching effects are achieved as the viewing angle changes in different planes. In particular, a first optical Change effect by "rockers" and a second optical switching effect by "tilting", ie by pivoting about two mutually perpendicular axes, which are both parallel to the substrate achieved. In other words, the viewing angle is changed in two mutually perpendicular planes, which are both perpendicular to the planes of the substrate, by "rocking" and "tilting".
Während das Maskenmuster naturgemäß deckend (opak) ist, kann oder muß das Bildmuster transluzent (optisch teildurchlässig) sein, insbesondere wenn eine rückseitige Beleuchtung bei der Betrachtung vorgesehen ist. Für eine Betrachtung ohne rückseitige Beleuchtung ist es hingegen zweckmäßig, die der Betrachtungsseite abgewandte Fläche mit einer reflektierenden Beschichtung zu versehen.While that Mask pattern naturally opaque (opaque) is, can or must be Image pattern translucent (optically semitransparent), especially if a back Lighting is provided when viewing. For a consideration without back Lighting, however, it is appropriate that of the viewing page opposite surface with to provide a reflective coating.
