- FIGS. 1 and 2 show a schematic representation of a banknote 10, the feature of the invention in the form of a in Fig. 2 has a see-through area 12 shown in more detail.
- the see-through area 12 formed by a family of curves of a plurality of straight, diverging cut lines 22 by the action of laser radiation in the banknote paper 20 were cut.
- the family of curves of the cutting lines 22 has a cutting width of 0.15 mm and the center-to-center spacing of the cutting lines is between 0.4 mm at the lower edge and 1.0 mm at the upper edge of the see-through region 12.
- the area coverage The cutting lines is thus between 15% and 37.5%, so that the viewing area 12 can be seen both in supervision and in transparency.
- the see-through area 12 is in the form of a geometric pattern, for example of the in Fig. 2 formed oval formed. Its outline is indicated in the figure by the dashed line border 24 and serves only the graphic illustration of the formed shape.
- a marking 30 is arranged, which, compared to the surrounding see-through area 12, in the reflected light and / or transmitted light has a changed visual appearance and is therefore recognizable to a viewer.
- the marking 30 is generally in the form of a pattern, of a character or a coding and in the exemplary embodiment has the shape of a maple leaf.
- the dashed line outline 34 of the marking 30 is merely a graphic illustration of their shape and does not necessarily correspond to an actually existing contour on the banknote.
- the marking 30 is also formed by a family of curves consisting of a plurality of straight, diverging cutting lines 32, wherein the cutting lines 32 of the marking 30 are perfectly matched to the cutting lines 22 of the see-through region 12 located outside the marking.
- the cutting lines 32 within However, the marking 30 is formed with a cutting width of 0.3 mm and thus much wider than the outside of the marking present cutting lines 22. Due to the lower area coverage of the paper in the area of the marking 30 is formed by the mark motif "maple leaf" depending on to clearly recognize the light conditions and the background in reflected light and / or transmitted light.
- the perfect registration of the differently wide cutting lines 22, 32 is ensured by the fact that the cutting lines 22, 32 are produced by laser cutting with the same cutting laser beam in the same operation.
- the different cutting widths are generated by a variation of the laser parameters, in particular a variation of the laser power and / or the cutting speed during the cutting process.
- Fig. 3 (a) shown the substantially Gaussian spatial distribution of the power W of a cutting laser beam.
- the energy input of the laser radiation into the paper exceeds the threshold energy needed to cut the paper 20 in a wide cutting area 42.
- the threshold energy needed to cut the paper 20 becomes only exceeded in a narrower cutting area 46, so that a smaller cutting width results.
- the cutting width of the laser beam along the laser beam guide can be varied as desired.
- contiguous cutting lines 22, 32 can be produced in a single operation as continuous and thus perfectly matched cutting lines.
- the laser power and thus the cutting width is increased and the transition from the area of the marking 30 (cutting lines 32) in the see-through area 12 (section lines 22) Laser power and thus the cutting width again lowered.
- This is especially good in the detail of the Fig. 3 (b) which shows the transition of a wide cutting line 32 within the marking 30 (width 42, here 0.3 mm) to a narrow cutting line outside the marking (width 46, here 0.15 mm) exactly at the edge 34 of the marking 30.
- the change in the cutting width 42, 46 can also be achieved by changing the cutting speed at a constant laser power.
- the laser radiation acts only relatively briefly on the paper, so that the energy input into the paper is low. Accordingly, the threshold energy needed to cut the paper is exceeded only in a narrow cutting area with high laser power.
- the laser radiation acts longer on the paper, resulting in a higher energy input into the paper. Accordingly, there is a wider cutting area in which the threshold energy needed to cut the paper is exceeded.
- the two parameters laser power and cutting speed can of course also be changed together and simultaneously to have a wider range of variation available.
- Fig. 4 shows a see-through area 50, in which the lying outside the mark 54 cutting lines 52 as in Fig. 2 produced by laser cutting.
- the family of curves of the see-through area 50 is formed by curved, equidistant lines of intersection 52.
- the laser power of the cutting laser was lowered below the cutting threshold of the paper 20, so that no cutting lines were produced there.
- the marking 54 thus remains as an uncut piece of paper and can be seen clearly against the background of the rastered viewing area 50, especially in transmitted light.
- Fig. 5 shows a further embodiment of the invention with a see-through area 60, in which the family of curves of lying outside of the marking 64 cutting lines is formed by curved and divergent cutting lines 62.
- Fig. 5 further illustrates the optional marking of the outer contour 66 of the marker 64 using laser radiation.
- the banknote paper 20 is provided with a laser-modifiable marking substance whose visible color is changeable by the action of the laser radiation.
- the laser parameters were then adjusted so that the laser energy is above the entire beam diameter below the cutting threshold of the paper, but in an inner region still above the reaction threshold of the laser-modifiable marker and thus causes a desired color change.
- Fig. 6 shows in a detailed view like Fig. 3 (b) an embodiment of an advantageous variant of the invention, in which the see-through region 70 and the marking 80 are both formed by a plurality of curved and / or diverging cutting lines 72 and 82, respectively.
- the cut lines 72, 82 adjoin each other at the edge 86 of the marking in perfect register, wherein, as in the embodiment of FIG Fig. 2 the cutting width of the cutting lines 72 outside the marking 80 is selected smaller than the cutting width of the cutting lines 82 within the marking 80 by suitable variation of the laser parameters.
- both the cut lines 82 within the tag and the cut lines 72 outside the tag are each surrounded on both sides by a perfectly matched colored edge 74 and 84, respectively.
- the banknote paper 20 was provided with a laser-modifiable feature substance, for example with laser-modifiable effect pigments, before the laser cutting in a certain environment of the see-through region 70 to be produced, which would be a desired one upon exposure to laser radiation Color change, from colorless to red, show.
- FIG Fig. 7 illustrates where the spatial power distribution 90 of the cutting laser beam is shown schematically.
- the laser energy exceeds the threshold energy E 1 required to cut the paper 20.
- E 2 is in Fig. 7 denotes the reaction energy of the effect pigments, when exceeded the desired color change takes place.
- the marking region 94 the laser energy lies between the energy E 2 required for the color change and the energy Ei required for cutting, so that a color change of the effect pigments is induced in the marking region 94 but the carrier is not cut.
- the banknote paper 20 provided with the laser-modifiable effect pigments is therefore irradiated by the laser beam 90 in a central region 72 and 82, respectively, corresponding to the cutting region 92 of FIG Fig. 7 corresponds, cut and additionally colored in an edge region 74, 84 in perfect registration to the cutting lines 72 and 82.
- the width of the colored edge region 74, 84 corresponds to the width of the marking region 94 and depends on the beam profile, the reaction energy of the effect pigments used and the material properties of the paper. Outside the cutting region 92 and the marking region 94, the laser energy is below the reaction threshold of the effect pigments, so that the paper is not changed there.
- the outer contour 66 of the marking 64 can be marked by means of the laser radiation, as in FIG Fig. 5 illustrated.
- the laser parameters are adjusted so that the laser energy over the entire beam diameter below the cutting threshold of the paper, but in an inner region is still above the reaction threshold of the effect pigments, for example by selecting a laser energy between E 1 and E 2 in Fig. 7 ,
- Fig. 8 shows a further embodiment of a see-through area 100 according to the invention, in which the lying outside of the marking 110 cutting lines 102 as in Fig. 6 are produced by laser cutting a banknote paper 20 provided with a marker along with a matched colored edge 104.
- the laser parameters of the cutting laser were changed so that the energy input into the paper below the cutting threshold of the paper 20, but still above the reaction threshold of the marker at the transition into the region of the label 110 lies.
- the laser beam generated within the marking 110 no longer cutting lines with colored edge, but only colored marking lines 112, the perfectly aligned to match the boundary 116 of the marking 110 to the cutting lines 102.
- Such a smooth transition from colored marking lines to color-edged cutting lines is visually appealing, easy to prove, and also makes it difficult for a counterfeiter to overcome a technical hurdle.
- the exemplary embodiment shown there includes a see-through region 120, which has, outside a marking 130, both a family of curves consisting of cutting lines 122 with a colored edge 124 and a marker curve group of colored marking lines 126 without a cutting region.
- both the cut lines 122 and the marking lines 126 may be curved and equidistant, curved and diverging, or straight and divergent.
- both the colored marking lines 126 and the color-edged cutting lines 122 in perfect registration pass over into colored marking lines 132.
- the two types of lines 122, 126 of the see-through region 120 are arranged alternately, but other sequences, for example of two cutting lines 122 and one marking line 126, are also conceivable. Since the marker set does not contain cut lines, it can also be arranged at any angle to the set of curves of the cut lines.
- the relative arrangement of the cut-line curve family and the marking can form a further authenticity feature.
- FIG. 10 For illustration shows Fig. 10 in (a) and (b) two copies of a banknote, in which a see-through area 140 is formed by curved, equidistant cut lines 142, as in connection with Fig. 4 already explained in principle.
- a marking 144 which here is in the form of the denomination "10" of the banknote, the laser power of the cutting laser was lowered below the cutting threshold of the paper so that no cutting lines were produced there.
- FIGS. 10 (a) and (b) differ now by the phase position of the curved cut lines 142 relative to the label 144. While in Fig. 10 (a) the curvature bellies of the cut lines 142 at the upper edge of the label 144 to the left (arrangement 1, reference numeral 146), they show in Fig. 10 (b) there to the right (arrangement 2, reference number 148).
- the phase position of the cutting lines 142 can now be selected, for example, according to the serial number of the respective banknote copy, such as arrangement 1 for the serial number range 0000001 to 0100000, arrangement 2 for the serial number range 0100001 to 0200000, then again arrangement 1 for the serial number range 0200001 to 0300000, and so on .
- the serial number of the respective banknote copy such as arrangement 1 for the serial number range 0000001 to 0100000, arrangement 2 for the serial number range 0100001 to 0200000, then again arrangement 1 for the serial number range 0200001 to 0300000, and so on .
- cut-line curves can be used for coding, for example the slope (rising / falling), the divergence (opening up / down or right / left opening) or the radius of curvature (increasing / decreasing).
- the identification in reflected light is virtually undetectable, but becomes clear when the data carrier is viewed in transmitted light.
- Fig. 11 shows in cross-section a data carrier according to the invention, in which a transparent film 150 is covered on both sides by opaque cover layers 152.
- the film 150 includes a feature area 154 having a plurality of curved and / or diverging cut lines 156 and a mark 158 disposed within the feature area.
- the mark 158 may be as shown in FIG Fig. 11 may be formed by an uncut portion of the film 150, or in other embodiments may be formed by, for example, a portion having cut lines of different widths.
- the marking 158 can be detected by machine, for example by an ultrasonic sensor 160. It lends itself to the only to combine machine-detectable markings with a coding by the relative arrangement of cut-line curves and marking, as related to Fig. 10 already explained in principle.

Die Erfindung betrifft einen Datenträger, insbesondere ein Wertdokument, wie eine Banknote, Ausweiskarte und dergleichen, mit einem Merkmalsbereich sowie ein Verfahren zum Herstellen eines derartigen Datenträgers.The invention relates to a data carrier, in particular a value document, such as a banknote, identity card and the like, with a feature area and a method for producing such a data carrier.
Datenträger, wie Sicherheits-, Wert- oder Ausweisdokumente, aber auch andere Wertgegenstände werden zur Absicherung oft mit Sicherheitsmerkmalen ausgestattet, die eine Überprüfung der Echtheit des Datenträgers gestatten und die zugleich als Schutz vor unerlaubter Reproduktion dienen. Dabei gewinnen zunehmend Durchsichtssicherheitsmerkmale, wie etwa Durchsichtsfenster in Banknoten, an Attraktivität. Zur Fenstererzeugung wird dabei beispielsweise eine auf einer Seite mit einer Kleberschicht versehene Folie auf eine Banknote aufgebracht, um eine zuvor erzeugte durchgehende Öffnung der Banknote zu verschließen.Data carriers, such as security, value or identity documents, but also other valuables are often equipped with security features for security, which allow verification of the authenticity of the data carrier and at the same time serve as protection against unauthorized reproduction. Increasingly transparent security features, such as transparent windows in banknotes, are becoming increasingly attractive. For window production, for example, a film provided with an adhesive layer on one side is applied to a banknote in order to close a previously produced through opening of the banknote.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, Datenträger der eingangs genannten Art hinsichtlich ihrer Nachahmungssicherheit und ihres visuellen Erscheinungsbilds weiter zu verbessern.Based on this, the present invention has the object to further improve data carriers of the type mentioned in terms of their imitation security and their visual appearance.
Diese Aufgabe wird durch den Datenträger und das Herstellungsverfahren mit den Merkmalen der unabhängigen Ansprüche gelöst. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the data carrier and the production method having the features of the independent claims. Further developments of the invention are the subject of the dependent claims.
Gemäß der Erfindung enthält ein gattungsgemäßer Datenträger, insbesondere ein Wertdokument, wie eine Banknote, Ausweiskarte und dergleichen, ein Substrat, in dem durch eine Kurvenschar aus einer Mehrzahl von gekrümmten und/oder divergierenden Schnittlinien ein Merkmalsbereich gebildet ist, wobei innerhalb dieses Merkmalsbereichs eine visuell und/oder maschinell erfassbare Kennzeichnung in Form eines Musters, von Zeichen oder einer Codierung angeordnet ist.According to the invention, a generic data carrier, in particular a value document, such as a banknote, identity card and the like, contains a substrate in which a feature region is formed by a family of curves of a plurality of curved and / or divergent cutting lines, wherein within this feature region a visual and or by machine detectable marking in the form of a pattern, is arranged by characters or a coding.
Die Krümmung der Schnittlinien kann dabei konstant sein, wie einem Kreisbogen, entlang der Schnittlinien ab- oder zunehmen, oder auch undulieren, wie bei einem Wellenmuster. Divergente gerade Schnittlinien weisen keinen konstanten, sondern einen zunehmenden Abstand voneinander auf, wobei die Richtung, in der der Abstand zunimmt, im Rahmen der Erfindung beliebig ist. Gekrümmte Schnittlinien können äquidistant verlaufen, können divergent verlaufen oder können auch mit bereichsweise unterschiedlichem Abstandverhalten verlaufen.The curvature of the cut lines can be constant, such as a circular arc, along the cut lines increase or decrease, or undulate, as in a wave pattern. Divergent straight cutting lines have no constant, but an increasing distance from each other, wherein the direction in which the distance increases, in the invention is arbitrary. Curved cut lines may be equidistant, may be divergent, or may be spaced apart with varying distances.
In einem Erfindungsaspekt ist die Kennzeichnung durch eine Kurvenschar aus einer Mehrzahl von gekrümmten und/oder divergierenden Schnittlinien gebildet, so dass die Schnittlinien der Kennzeichnung erste Schnittlinien bilden und die außerhalb der Kennzeichnung liegenden Schnittlinien des Merkmalsbereichs zweite Schnittlinien bilden, wobei die ersten und zweiten Schnittlinien aneinander anschließen und unterschiedliche Schnittbreite aufweisen. Durch die unterschiedlichen Schnittbreiten der ersten und zweiten Schnittlinien und der resultierenden unterschiedlichen Flächendeckung ist die Kennzeichnung innerhalb des umgebenden Durchsichtsbereichs im Durchlicht und/oder Auflicht visuell erkennbar, oder im Fall einer Abdeckung durch opake Deckschichten maschinell nachweisbar.In one aspect of the invention, the tag is formed by a family of curves of a plurality of curved and / or divergent cut lines such that the cut lines of the tag form first cut lines and the cut lines of the feature area lying outside the tag form second cut lines, with the first and second cut lines contiguous connect and have different cutting width. Due to the different cutting widths of the first and second cutting lines and the resulting different area coverage, the marking within the surrounding see-through area in transmitted light and / or reflected light is visually recognizable, or in the case of a cover by opaque cover layers can be detected by machine.
Die Breite der ersten Schnittlinien kann dabei sowohl größer als auch kleiner als die Breite der zweiten Schnittlinien sein. Die breiteren Schnittlinien sind dabei insbesondere um mindestens 10%, mindestens 20%, mindestens 50% oder sogar um mehr als 100% breiter als die schmäleren Schnittlinien. Die Schnittbreite der ersten und zweiten Schnittlinien ist in vorteilhaften Gestaltungen jeweils im Wesentlichen konstant. Die Formulierung "im Wesentlichen konstant" trägt dabei der Tatsache Rechnung, dass die Schnittbreite beim Laserschneiden in der Praxis auch bei gleichen Einstellungen leicht variieren und daher nicht vollkommen konstant sein kann.The width of the first cutting lines can be both larger and smaller than the width of the second cutting lines. In particular, the wider cut lines are at least 10%, at least 20%, at least 50% or even more than 100% wider than the narrower cut lines. The cutting width of the first and second cutting lines is in advantageous configurations each substantially constant. The phrase "substantially constant" takes into account the fact that the cutting width of laser cutting in practice, even with the same settings vary slightly and therefore can not be completely constant.
In einer bevorzugten Erfindungsvariante ist das Substrat im Merkmalsbereich mit einem lasermodifizierbaren Markierungsstoff versehen, und es weisen zumindest die außerhalb der Kennzeichnung liegenden Schnittlinien des Merkmalsbereichs einen durch Einwirkung von Laserstrahlung modifizierten Randbereich auf. Liegen innerhalb der Kennzeichnung ebenfalls Schnittlinien vor, so weisen auch diese mit Vorteil einen durch die Einwirkung von Laserstrahlung modifizierten Randbereich auf. In anderen Gestaltungen ist der Bereich der Kennzeichnung ungeschnitten, insbesondere lediglich mit Markierungslinien oder Markierungskonturen versehen, wie weiter unten ausgeführt. Das Substrat kann insbesondere mit einem Markierungsstoff versehen sein, dessen sichtbare Farbe durch die Einwirkung der Laserstrahlung veränderbar ist. Die außerhalb der Kennzeichnung liegenden Schnittlinien des Merkmalsbereichs und gegebenenfalls auch die innerhalb der Kennzeichnung vorliegenden Schnittlinien weisen dann einen farbigen Randbereich auf.In a preferred variant of the invention, the substrate is provided with a laser-modifiable marking substance in the feature area, and at least the sectional lines of the feature area lying outside the marking have an edge area modified by the action of laser radiation. If there are also cutting lines within the marking, then these also advantageously have an edge region modified by the action of laser radiation. In other embodiments, the area of the marking is uncut, in particular provided only with marking lines or marking contours, as explained below. The substrate may in particular be provided with a marking substance whose visible color can be changed by the action of the laser radiation. The sectional lines of the feature area lying outside the marking and optionally also the cutting lines present within the marking then have a colored border area.
Alternativ oder zusätzlich kann das Substrat mit einem Markierungsstoff versehen sein, dessen Infrarot-absorbierende, magnetische, elektrische oder lumineszierende Eigenschaften durch die Einwirkung der Laserstrahlung veränderbar sind. Die außerhalb der Kennzeichnung liegenden Schnittlinien des Merkmalsbereichs und gegebenenfalls auch die innerhalb der Kennzeichnung vorliegenden Schnittlinien weisen dann einen Randbereich mit gegenüber ihrem Umfeld veränderten Infrarot-absorbierenden, magnetischen, elektrischen oder lumineszierenden Eigenschaften auf. Derartige Gestaltungen gestatten eine einfache ergänzende maschinelle Echtheitsprüfung des Merkmalsbereichs. Selbstverständlich sind auch Varianten denkbar, die eine Echtheitsprüfung mit bloßem Auge oder einfachem Hilfsmittel, wie z.B. eine UV-Lampe, ermöglichen.Alternatively or additionally, the substrate may be provided with a marking substance whose infrared-absorbing, magnetic, electrical or luminescent properties can be changed by the action of the laser radiation. The cut-off lines of the feature area lying outside the marking and, if appropriate, also the cutting lines present within the marking then have an edge area with infrared-absorbing, magnetic, electrical or luminescent properties which are changed with respect to their surroundings. Such designs allow a simple complementary mechanical authentication of the feature area. Of course, variants are conceivable that allow an authenticity check with the naked eye or simple aids, such as a UV lamp.
Als Markierungsstoff können vorteilhaft lasermodifizierbare Effektpigmente eingesetzt werden. Solche Effektpigmente stehen dem Fachmann mit unterschiedlichen Eigenschaften, insbesondere bezüglich ihrer Körperfarbe, dem Farbumschlag unter Lasereinwirkung, der Schwellenergie und der benötigten Laserwellenlänge zur Verfügung. Auch Effektpigmente, die bei Laserbestrahlung nicht (nur) ihre sichtbare Farbe, sondern ihre Infrarot-absorbierenden, magnetischen, elektrischen oder lumineszierenden Eigenschaften verändern, sind dem Fachmann bekannt. Die Modifikation der Effektpigmente kann mit Laserstrahlung im ultravioletten, sichtbaren oder infraroten Spektralbereich beispielsweise mit einem CO2-Laser einer Wellenlänge von 10,6 µm erfolgen.As a marker, laser-modifiable effect pigments can advantageously be used. Such effect pigments are available to the person skilled in the art with different properties, in particular with respect to their body color, the color change under laser action, the threshold energy and the required laser wavelength. Also, effect pigments which do not (only) change their visible color upon laser irradiation but their infrared-absorbing, magnetic, electrical or luminescent properties are known to the person skilled in the art. The modification of the effect pigments can be made with laser radiation in the ultraviolet, visible or infrared spectral range, for example, a CO 2 laser of a wavelength of 10.6 microns.
Bei einer anderen ebenfalls vorteilhaften Erfindungsvariante wird ein pigmentfreier lasermodifizierbarer Markierungsstoff eingesetzt. Auch pigmentfreie Markierungsstoffe können, beispielsweise als Stich- oder Druckfarbe, auf das Substrat aufgebracht oder in das Substratvolumen eingebracht werden. Mit pigmentfreien Markierungsstoffen lässt sich eine Beschichtung hoher Transparenz erzeugen, in die durch Lasereinwirkung mit hoher Geschwindigkeit eine dauerhafte und kontrastreiche Markierung eingebracht werden kann. Pigmentfreie Markierungsstoffe können durch Laserstrahlung im ultravioletten, sichtbaren oder infraroten Spektralbereich beispielsweise mit der 10,6 µm-Strahlung eines CO2-Lasers modifiziert werden. Konkrete, nicht beschränkende Beispiele für pigmentfreie lasermodifizierbare Markierungsstoffe sind in den Druckschriften
Nach einem anderen Erfindungsaspekt ist die Kennzeichnung durch einen ungeschnittenen Bereich des Substrats mit einer Markierungskurvenschar aus einer Mehrzahl von Markierungslinien gebildet, die an die Schnittlinien außerhalb der Kennzeichnung anschließen. Allgemein bezeichnet der Begriff "Markierungslinien" im Rahmen dieser Beschreibung stets ungeschnittene, lediglich markierte Linien. Linien, die sowohl einen inneren Schnittbereich als auch einen äußeren Markierungsbereich aufweisen, sind ebenfalls möglich und werden als (farbig) berandete Schnittlinien oder Schnittlinien mit (farbigem) Rand bezeichnet.According to another aspect of the invention, the marking is formed by an uncut portion of the substrate having a marker curve set of a plurality of marker lines which adjoin the cut lines outside the marker. In general, the term "marking lines" in the context of this description always means uncut, only marked lines. Lines which have both an inner cut area and an outer mark area are also possible and are referred to as (color) bordered cut lines or cut lines with (colored) borders.
Die Kennzeichnung ist bei dieser Erfindungsvariante als ungeschnittener Teil des Substrats im Durchlicht gut zu erkennen und durch die Markierungslinien auch im Aufsicht deutlich sichtbar.In this variant of the invention, the marking can be easily recognized as an uncut part of the substrate in transmitted light and can be clearly seen through the marking lines even in the top view.
Das Substrat ist dabei vorzugsweise mit einem Markierungsstoff versehen, dessen sichtbare Farbe durch die Einwirkung der Laserstrahlung veränderbar ist, so dass die Markierungslinien der Kennzeichnung farbig sind. Alternativ oder zusätzlich kann das Substrat auch mit einem Markierungsstoff versehen sein, dessen Infrarot-absorbierende, magnetische, elektrische oder lumineszierende Eigenschaften durch die Einwirkung der Laserstrahlung veränderbar sind, so dass die Markierungslinien der Kennzeichnung gegenüber ihrem Umfeld veränderte Infrarot-absorbierende, magnetische, elektrische oder lumineszierende Eigenschaften aufweisen. Als Markierungsstoffe kommen auch hier die oben erwähnten Stoffe in Betracht.The substrate is preferably provided with a marking substance whose visible color is changeable by the action of the laser radiation, so that the marking lines of the marking are colored. Alternatively or additionally, the substrate may also be provided with a marker whose infrared-absorbing, magnetic, electrical or luminescent properties can be changed by the action of the laser radiation, so that the marking lines of the marking relative to their environment have changed infrared-absorbing, magnetic, electrical or luminescent properties. As markers, the abovementioned substances are also suitable here.
Bei geeigneten Laserparametern kann eine farbige Markierungslinie auch ohne zusätzlichen Markierungsstoff erzeugt werden, beispielsweise indem durch Verbrennungsvorgänge sich die Papierfasern verfärben oder indem sich die Opazität eines Polymersubstrats verändert.With suitable laser parameters, a colored marking line can also be produced without additional marking substance, for example by the paper fibers becoming discolored by combustion processes or by the opacity of a polymer substrate changing.
Bei einer weiteren vorteilhaften Erfindungsvariante ist die Kennzeichnung durch einen ungeschnittenen Bereich des Substrats mit mehreren ineinander liegenden Markierungskonturen abnehmender Größe gebildet. Die Markierungskonturen bilden dabei zweckmäßig die Form der Kennzeichnung nach, wobei mit zunehmender Verkleinerung nicht mehr alle Details der Außenkontur der Kennzeichnung dargestellt werden müssen. Auch bei einer solchen Gestaltung ist die Kennzeichnung mit dem dargestellten Markierungsmotiv im Auflicht deutlich erkennbar.In a further advantageous variant of the invention, the marking is formed by an uncut area of the substrate with a plurality of mutually contiguous marking contours of decreasing size. The marking contours expediently follow the form of the marking, whereby with increasing reduction not all details of the outer contour of the marking must be displayed. Even with such a design, the marking with the illustrated marking motif in reflected light is clearly visible.
Wie bei der vorhergehenden Erfindungsvariante kann das Substrat auch bei dieser Variante mit einem Markierungsstoff versehen sein, dessen sichtbare Farbe und/oder dessen Infrarot-absorbierende, magnetische, elektrische oder lumineszierende Eigenschaften durch die Einwirkung der Laserstrahlung veränderbar sind, so dass die Markierungskonturen entsprechend veränderte Eigenschaften aufweisen.As in the previous variant of the invention, the substrate can also be provided in this variant with a marker whose visible color and / or its infrared-absorbing, magnetic, electrical or luminescent properties can be changed by the action of the laser radiation, so that the marking contours correspondingly changed properties respectively.
In allen Gestaltungen kann innerhalb der Kennzeichnung eine durchgehende Motivöffnung in Form eines Musters, von Zeichen oder einer Codierung angeordnet sein. In vorteilhaften Gestaltungen steht die Form der Motivöffnung mit der Form der Kennzeichnung in einem Sinnzusammenhang. Ein solcher Sinnzusammenhang kann insbesondere darin bestehen, dass die Motivöffnung das gleiche Motiv wie die Kennzeichnung darstellt, wobei sich die räumliche Lage und/oder die Größe der beiden dargestellten Motive unterscheiden können. Der Sinnzusammenhang kann auch darin bestehen, dass das erste und zweite dargestellte Motiv jeweils nur Motivteile bilden, die sich zu einem Gesamtmotiv ergänzen, oder darin, dass sich das erste und zweite dargestellte Motiv zu einem schlüssigen Gesamtbild ergänzen.In all designs, a continuous motif opening in the form of a pattern, a character or a coding can be arranged within the marking his. In advantageous embodiments, the shape of the motif opening is in a meaningful relationship with the shape of the marking. Such a context of meaning may in particular consist in that the motif opening represents the same motif as the marking, wherein the spatial position and / or the size of the two motifs shown may differ. The context of meaning can also consist in the fact that the first and second motif shown only form parts of the motif that complement each other, or that the first and second depicted motifs complement each other to form a conclusive overall picture.
Auch der Merkmalsbereich selbst kann in allen Gestaltungen in Form eines Musters, von Zeichen oder einer Codierung ausgebildet sein, wobei die Form des Merkmalsbereichs mit der Form der Kennzeichnung und/oder einer gegebenenfalls vorhandenen Motivöffnung in einem Sinnzusammenhang stehen kann. Die Formen von Merkmalsbereich, Kennzeichnung und Motivöffnung können jedoch auch unabhängig voneinander gewählt werden und jeweils eigenständige Motive darstellen.The feature area itself can also be embodied in all designs in the form of a pattern, of characters or of an encoding, wherein the shape of the feature area can be correlated with the form of the marking and / or an optionally existing motif opening. The forms of feature area, marking and motif opening, however, can also be selected independently of each other and each represent independent motifs.
Bei einer Weiterbildung der Erfindung weist der Merkmalsbereich neben der Kurvenschar aus der Mehrzahl von gekrümmten und/oder divergierenden Schnittlinien auch eine Markierungskurvenschar aus einer Mehrzahl von Markierungslinien auf, vorzugsweise aus einer Mehrzahl von gekrümmten und/oder divergierenden Markierungslinien. Die Schnittlinien und die Markierungslinien können dabei zueinander einen beliebigen Winkel einschließen. Die Kennzeichnung ist in dieser Weiterbildung mit Vorteil durch einen ungeschnittenen Bereich des Trägers mit zwei Markierungskurvenscharen aus jeweils einer Mehrzahl von Markierungslinien gebildet, wobei die Markierungslinien der einen Markierungskurvenschar an die Schnittlinien außerhalb der Kennzeichnung anschließen und die Markierungslinien der anderen Markierungskurvenschar an die Markierungslinien außerhalb der Kennzeichnung anschließen.In a further development of the invention, the feature area in addition to the family of curves from the plurality of curved and / or diverging cut lines and a Markierungskurvenschar from a plurality of marking lines, preferably from a plurality of curved and / or divergent marking lines. The cutting lines and the marking lines can include any angle to each other. The marking is advantageously formed in this development by an uncut area of the carrier with two marker curves from each of a plurality of marking lines, wherein the marking lines of a Markingskurschar connect to the cutting lines outside the label and the marking lines connect the other marker set to the mark lines outside the mark.
Nach einer weiteren vorteilhaften Erfindungsvariante ist der Umriss der Kennzeichnung mit einer Markierungskontur, insbesondere einer farbigen Markierungskontur versehen, um die Erkennbarkeit der Kennzeichnung im Auflicht zu erhöhen.According to a further advantageous variant of the invention, the outline of the marking is provided with a marking contour, in particular a colored marking contour, in order to increase the recognizability of the marking in incident light.
In allen Gestaltungen sind die Schnittlinien vorzugsweise mit einer Breite zwischen 0,05 mm und 1 mm ausgebildet. Der Mitte-zu-Mitte-Abstand liegt vorzugsweise zwischen 0,05 mm und 3 mm, insbesondere zwischen 0,5 mm und 1,5 mm, wobei der Mitte-zu-Mitte-Abstand konstant (äquidistante Schnittlinien) oder variabel (divergierende Schnittlinien) sein kann. Bei Schnittlinien mit Randbereich liegt die Breite des Randbereichs auf jeder Seite vorzugsweise zwischen 0,02 mm und 1 mm und reine Markierungslinien ohne Schnittbereich weisen vorzugsweise eine Breite zwischen 0,05 mm und 3 mm auf.In all configurations, the cutting lines are preferably formed with a width between 0.05 mm and 1 mm. The center-to-center distance is preferably between 0.05 mm and 3 mm, in particular between 0.5 mm and 1.5 mm, wherein the center-to-center distance is constant (equidistant cut lines) or variable (divergent cut lines ) can be. For edge-line cut lines, the width of the edge region on each side is preferably between 0.02 mm and 1 mm, and pure marker lines without a cut region preferably have a width between 0.05 mm and 3 mm.
In einer vorteilhaften Erfindungsvariante ist die Kurvenschar des Merkmalsbereichs aus einer Mehrzahl von gekrümmten, äquidistanten Schnittlinien gebildet. Bei einer anderen ebenfalls vorteilhaften Erfindungsvariante ist die Kurvenschar des Merkmalsbereichs aus einer Mehrzahl von geraden, divergierenden Schnittlinien gebildet.In an advantageous variant of the invention, the set of curves of the feature area is formed from a plurality of curved, equidistant cut lines. In another likewise advantageous variant of the invention, the family of curves of the feature area is formed from a plurality of straight, divergent cutting lines.
In einer zweckmäßigen Weiterbildung der Erfindung bildet die relative Anordnung von Schnittlinien-Kurvenschar und Kennzeichnung ein weiteres Echtheitsmerkmal, bei dem für unterschiedliche Exemplare des Datenträgers unterschiedliche relative Anordnungen von Schnittlinien-Kurvenschar und Kennzeichnung wählbar sind.In an expedient development of the invention, the relative arrangement of intersection curves and marking forms another authenticity feature in which different relative arrangements of intersection curves and marking can be selected for different copies of the data carrier.
Der Merkmalsbereich des Datenträgers ist mit Vorteil durch ein Folienelement verstärkt. Das Folienelement kann dabei eine Kurvenschar enthalten, die mit der Kurvenschar des Merkmalsbereichs einen Moireeffekt erzeugt. Beispielsweise kann der Mitte-zu-Mitte-Abstand der Kurvenschar des Folienelements leicht (beispielsweise einige Prozent) von dem Mitte-zu-Mitte-Abstand der Kurvenschar des Merkmalsbereichs abweichen und/oder die beiden Kurvenscharen können leicht (beispielsweise um einige Grad) gegeneinander gedreht sein.The feature area of the data carrier is advantageously reinforced by a film element. The film element may contain a family of curves that generates a moire effect with the family of curves of the feature area. For example, the center-to-center distance of the family of curves of the sheet element may slightly deviate (eg, a few percent) from the center-to-center distance of the family of curves of the feature area and / or the two sets of curves may be slightly rotated (e.g., a few degrees) relative to each other his.
Es ist jedoch auch möglich, einen Merkmalsbereich ohne zusätzliches Folienelement als Sicherheitselement einzusetzen. Bei dem Datenträger kann es sich insbesondere um ein Sicherheitselement, ein Sicherheitspapier oder ein Wertdokument handeln.However, it is also possible to use a feature area without additional foil element as a security element. The data carrier can in particular be a security element, a security paper or a value document.
In einer vorteilhaften Erfindungsvariante bildet der Merkmalsbereich einen Durchsichtsbereich, in dem die Kennzeichnung im Auflicht und/oder Durchlicht ein gegenüber dem restlichen Merkmalsbereich verändertes visuelles Erscheinungsbild erzeugt.In an advantageous variant of the invention, the feature area forms a see-through area, in which the marking in reflected light and / or transmitted light produces a visual appearance which is changed in relation to the remaining feature area.
Nach einer anderen ebenfalls vorteilhaften Erfindungsvariante ist der Merkmalsbereich auf einer oder beiden Datenträgerseiten mit einer Deckschicht geringer Lichtdurchlässigkeit abgedeckt, so dass die Kennzeichnung im Auflicht im Wesentlichen nicht sichtbar ist und erst bei Betrachtung im Durchlicht hervortritt.According to another likewise advantageous variant of the invention, the feature area on one or both data carrier sides is covered with a cover layer of low light transmittance, so that the marking is essentially invisible in incident light and emerges only when viewed in transmitted light.
Schließlich kann nach einer weiteren vorteilhaften Erfindungsvariante der Merkmalsbereich auf beiden Datenträgerseiten mit einer opaken Deckschicht abgedeckt sein, so dass die Kennzeichnung visuell nicht sichtbar, jedoch maschinell erfassbar ist, beispielsweise durch Ultraschall.Finally, according to a further advantageous variant of the invention, the feature area on both data carrier sides can be covered with an opaque cover layer, so that the marking is not visually visible, but can be detected mechanically, for example by ultrasound.
Die Erfindung enthält auch ein Verfahren zum Herstellen eines Datenträgers der oben genannten Art. Dabei wird in dem Substrat ein Merkmalsbereich gebildet, indem durch Laserschneiden eine Kurvenschar aus einer Mehrzahl von gekrümmten und/oder divergierenden Schnittlinien erzeugt wird, wobei innerhalb des Merkmalsbereichs eine visuell und/oder maschinell erfassbare Kennzeichnung in Form eines Musters, von Zeichen oder einer Codierung erzeugt wird.The invention also includes a method for producing a data carrier of the above-mentioned type. A feature region is formed in the substrate by generating a family of curves from a plurality of curved and / or divergent cutting lines by laser cutting, wherein within the feature region a visual and / or or machine-detectable identification in the form of a pattern, a character or an encoding is generated.
Die Kennzeichnung wird vorzugsweise durch eine Kurvenschar aus einer Mehrzahl von gekrümmten und/oder divergierenden ersten Schnittlinien gebildet, die durch denselben Schneidlaserstrahl wie die außerhalb der Kennzeichnung liegenden zweiten Schnittlinien des Merkmalsbereichs erzeugt werden und dass die ersten und zweiten Schnittlinien durch eine Variation der Laserparameter, insbesondere von Laserleistung und/oder der Schnittgeschwindigkeit, mit unterschiedlicher Schnittbreite erzeugt werden.The marking is preferably formed by a family of curves consisting of a plurality of curved and / or diverging first cutting lines, which are generated by the same cutting laser beam as the second cutting lines of the feature area lying outside the marking and in that the first and second cutting lines are formed by a variation of the laser parameters, in particular Laser power and / or the cutting speed, with different cutting width can be generated.
In einer vorteilhaften Verfahrensvariante wird das Substrat im Merkmalsbereich mit einem lasermodifizierbaren Markierungsstoff versehen, so dass die außerhalb der Kennzeichnung liegenden Schnittlinien durch die Einwirkung der Laserstrahlung in ihrem Randbereich modifiziert werden. Vorzugsweise werden auch die innerhalb der Kennzeichnung liegenden Schnittlinien durch die Einwirkung der Laserstrahlung in ihrem Randbereich modifiziert.In an advantageous variant of the method, the substrate is provided in the feature area with a laser-modifiable marking substance, so that the cutting lines lying outside the marking are modified by the action of the laser radiation in its edge area. Preferably, the cutting lines lying within the marking are modified by the action of the laser radiation in its edge region.
Nach einer weiteren vorteilhaften Verfahrensführung wird die Kennzeichnung durch einen ungeschnittenen Bereich des Substrats gebildet, vorzugsweise wird die Kennzeichnung durch einen ungeschnittenen Bereich des Substrats mit einer Markierungskurvenschar aus einer Mehrzahl von Markierungslinien gebildet, die durch denselben Laserstrahl wie die außerhalb der Kennzeichnung liegenden Schnittlinien des Durchsichtsbereichs erzeugt werden, und es werden die außerhalb der Kennzeichnung liegenden Schnittlinien und die Markierungslinien der Kennzeichnung durch eine Variation der Laserparameter, insbesondere der Laserleistung und/oder der Schnittgeschwindigkeit, erzeugt.According to a further advantageous process control, the marking is formed by an uncut area of the substrate, preferably the marking is formed by an uncut area of the substrate with a marker array of a plurality of marking lines which generates by the same laser beam as the cut-off lines of the see-through area are generated, and there are the off-label cutting lines and the marking lines of the marking by a variation of the laser parameters, in particular the laser power and / or the cutting speed generated.

Innerhalb des Durchsichtsbereichs 12 ist eine Kennzeichnung 30 angeordnet, die, verglichen mit dem umgebenden Durchsichtsbereich 12, im Auflicht und/oder Durchlicht ein verändertes visuelles Erscheinungsbild aufweist und dadurch für einen Betrachter erkennbar ist. Die Kennzeichnung 30 ist allgemein in Form eines Musters, von Zeichen oder einer Codierung ausgebildet und hat im Ausführungsbeispiel die Form eines Ahornblattes. Auch der gestrichelt eingezeichnete Umriss 34 der Kennzeichnung 30 dient lediglich der zeichnerischen Veranschaulichung ihrer Form und entspricht nicht notwendigerweise einer tatsächlich vorhandenen Kontur auf der Banknote.Within the see-through

Die perfekte Passerung der verschieden breiten Schnittlinien 22, 32 wird dadurch sichergestellt, dass die Schnittlinien 22, 32 durch Laserschneiden mit demselben Schneidlaserstrahl im selben Arbeitsgang erzeugt werden. Die unterschiedlichen Schnittbreiten werden durch eine Variation der Laserparameter, insbesondere eine Variation der Laserleistung und/oder der Schnittgeschwindigkeit, beim Schneidevorgang erzeugt.The perfect registration of the differently

Mit Bezug auf
Die Veränderung der Schnittbreite 42, 46 kann auch durch eine Änderung der Schnittgeschwindigkeit bei konstanter Laserleistung erreicht werden. Bei einer hohen Schnittgeschwindigkeit wirkt die Laserstrahlung nur relativ kurz auf das Papier ein, so dass der Energieeintrag ins Papier gering ist. Entsprechend wird die zum Schneiden des Papiers benötigte Schwellenenergie nur in einem schmalen Schnittbereich mit hoher Laserleistung überschritten. Bei einer niedrigeren Schnittgeschwindigkeit wirkt die Laserstrahlung dagegen länger auf das Papier ein, so dass ein höherer Energieeintrag ins Papier resultiert. Entsprechend ergibt sich ein breiterer Schnittbereich, in dem die zum Schneiden des Papiers benötigte Schwellenergie überschritten wird. Die beiden Parameter Laserleistung und Schnittgeschwindigkeit können selbstverständlich auch gemeinsam und gleichzeitig verändert werden um eine größere Variationsbreite zur Verfügung zu haben.The change in the

Um einen solchen zu den Schnittlinien perfekt gepasserten farbigen Rand 74, 84 zu erzeugen, wurde das Banknotenpapier 20 vor dem Laserschneiden in einer gewissen Umgebung des zu erzeugenden Durchsichtsbereichs 70 mit einem lasermodifizierbaren Merkmalsstoff, beispielsweise mit lasermodifizierbaren Effektpigmenten versehen, die bei Einwirkung von Laserstrahlung eine gewünschte Farbänderung, etwa von farblos zu rot, zeigen.In order to produce such a

Im gezeigten Ausführungsbeispiel sind die beiden Linienarten 122,126 des Durchsichtsbereichs 120 alternierend angeordnet, es sind jedoch auch andere Abfolgen, beispielsweise von je zwei Schnittlinien 122 und einer Markierungslinie 126, denkbar. Da die Markierungskurvenschar keine Schnittlinien enthält, kann sie auch in einem beliebigen Winkel zu der Kurvenschar der Schnittlinien angeordnet sein.In the exemplary embodiment shown, the two types of
In allen gezeigten Ausgestaltungen kann die relative Anordnung der Schnittlinien-Kurvenschar und der Kennzeichnung ein weiteres Echtheitsmerkmal bilden. Dazu wird die Schnittlinien-Kurvenschar für unterschiedliche Exemplare des Datenträgers relativ zur Kennzeichnung unterschiedlich angeordnet und diese unterschiedliche Anordnung mit einem weiteren Charakteristikum des Datenträgers, beispielsweise der Seriennummer, korreliert.In all the embodiments shown, the relative arrangement of the cut-line curve family and the marking can form a further authenticity feature. This is the cutting line set of curves for different copies the data carrier is arranged differently relative to the marking and this different arrangement with a further characteristic of the data carrier, such as the serial number, correlated.
Zur Illustration zeigt
Die beiden Banknotenexemplare der
Anstelle einer unterschiedlichen Phasenlage können auch andere Merkmale der Schnittlinien-Kurvenschar zur Codierung eingesetzt werden, beispielsweise die Steigung (ansteigend/ absteigend), die Divergenz (sich nach oben/ unten bzw. rechts/links öffnend) oder der Krümmungsradius (zunehmend/ abnehmend).Instead of a different phase position, other features of the cut-line curves can be used for coding, for example the slope (rising / falling), the divergence (opening up / down or right / left opening) or the radius of curvature (increasing / decreasing).
Wird der Merkmalsbereich auf einer oder beiden Seiten des Datenträgers mit einer Deckschicht geringer Lichtdurchlässigkeit abgedeckt, so ist die Kennzeichnung im Auflicht praktisch nicht zu erkennen, tritt jedoch bei Betrachtung des Datenträgers im Durchlicht deutlich hervor.If the feature area is covered on one or both sides of the data carrier with a cover layer of low light transmittance, then the identification in reflected light is virtually undetectable, but becomes clear when the data carrier is viewed in transmitted light.
Der Merkmalsbereich kann auch so gestaltet werden, dass die Kennzeichnung visuell völlig unsichtbar und nur maschinell erfassbar ist.
Da die Folie 150 beidseitig von opaken Deckschichten 152 abgedeckt ist, sind die Schnittlinien 156 und damit auch die Kennzeichnung 158 visuell nicht zu erkennen. Die Kennzeichnung 158 kann jedoch maschinell erfasst werden, beispielsweise durch eine Ultraschallsensorik 160. Es bietet sich an, die nur maschinell erfassbaren Kennzeichnungen mit einer Codierung durch die relative Anordnung von Schnittlinien-Kurvenschar und Kennzeichnung zu kombinieren, wie in Zusammenhang mit
