Description

Die Erfindung betrifft ein blattförmiges Wertdokument mit wenigstens einem lumineszierendem Merkmalsstoff und die Herstellung eines solchen Wertdokuments.The invention relates to a sheet-shaped value document with at least one luminescent feature substance and the production of such a value document.

Blattförmige Wertdokumente können beispielsweise Banknoten, Schecks, Aktien, Fahrkarten, Coupons, Urkunden, Gutscheine, hochwertige Eintrittskarten, aber auch andere fälschungsgefährdete Papiere, wie Pässe oder sonstige Ausweisdokumente oder auch noch nicht oder noch nicht vollständig bedruckte oder anderweitig bearbeitete Sicherheitspapiere sein, welche für die Herstellung z.B. von Banknoten verwendet werden. Obwohl nicht darauf beschränkt, wird nachfolgend exemplarisch auf Banknoten als solche Wertdokumente eingegangen.Leaf-shaped documents of value can be, for example, banknotes, checks, shares, tickets, coupons, certificates, vouchers, high-quality admission tickets, but also other papers that are subject to counterfeiting, such as passports or other identification documents or security papers that have not yet been printed or processed in any other way or which have not yet been processed Production eg be used by banknotes. Although not limited thereto, banknotes will be exemplified below as such value documents.

Im Sinne der vorliegenden Erfindung wird unter einem lumineszierenden Merkmalsstoff ein Stoff aus einer einzelnen Komponente oder einer Mischung von mehreren Komponenten verstanden, die ein Lumineszenzverhalten zeigen.For the purposes of the present invention, a luminescent feature substance is understood as meaning a substance composed of a single component or of a mixture of a plurality of components which exhibit a luminescence behavior.

Solche lumineszierenden Merkmalsstoffe werden üblicherweise direkt ins Papier oder die Druckfarbe zum Bedrucken der Banknoten eingebracht.Such luminescent feature substances are usually introduced directly into the paper or the printing ink for printing the banknotes.

Für kriminalistische Zwecke ist es hilfreich, wenn für die Absicherung von Banknoten Merkmalsstoffe verwendet werden, die selbst nach der Verbrennung des Dokuments noch nachweisbar sind, um sicherstellen zu können, dass ein unkenntlicher Verbrennungsrückstand tatsächlich von echten Dokumenten stammt. Andererseits muss verhindert werden, dass die in der Asche von verbrannten Wertdokumenten enthaltenen Merkmalsstoffe zurückgewonnen und zur Erstellung von Fälschungen verwendet werden.For criminal purposes, it is helpful to use feature substances that are still detectable even after the document has been burned to ensure that an unrecognizable incineration residue is actually from genuine documents. On the other hand, it must be prevented that the feature substances contained in the ashes of burnt documents of value be recovered and used to create counterfeits.

Zur Lösung dieses Problems wird nach der WO 00/39397 A1 der Anmelderin vorgeschlagen, ein Wertdokument mit einer ersten maschinell prüfbaren physikalischen oder chemischen Eigenschaft und mit einer zweiten maschinell prüfbaren physikalischen oder chemischen Eigenschaft zu versehen, wobei sich die erste und zweite prüfbare Eigenschaft voneinander getrennt maschinell prüfen lassen, das Wertdokument die erste prüfbare Eigenschaft bei einer ersten Temperatur verliert, und das Wertdokument die zweite prüfbare Eigenschaft bei einer zweiten Temperatur verliert, die von der ersten Temperatur verschieden ist.To solve this problem is after the WO 00/39397 A1 the applicant proposed to provide a value document with a first machine-testable physical or chemical property and a second machine-testable physical or chemical property, the first and second testable property can be checked separately from each other mechanically, the value document the first testable property in a loses first temperature, and the value document loses the second testable property at a second temperature, which is different from the first temperature.

Es gibt hierzu allerdings nur relativ wenige geeignete Merkmalsstoffe. Deshalb besteht ein Bedarf nach Alternativen hierzu, um eine größere Gruppe von Merkmalsstoffen zur Absicherung der Echtheit von Wertdokumenten einsetzen zu können.However, there are only relatively few suitable feature substances for this purpose. Therefore, there is a need for alternatives to this, in order to use a larger group of feature substances to secure the authenticity of value documents.

In US 4 557 596 ist ein Verfahren zur Aufrasterung von Halbtonbildmotiven beschrieben, bei dem die Grauwerte des Halbtonbildmotivs durch Veränderungen der Strukturstärke einer der Form nach beliebigen Rastergrundstruktur wiedergegeben werden. Die Zuordnung von Grauwertbereich des Halbtonbildmotivs zu der diesen Grauwertbereich wiedergebenden Rasterstrukturstärke ist gezielt festlegbar.In US 4 557 596 A method for halftoning of halftone motifs is described, in which the gray values of the halftone image motif are reproduced by changes in the structural strength of an arbitrary grid basic structure. The assignment of the gray value range of the halftone image motif to the raster structure strength reproducing this gray value range can be determined in a targeted manner.

In WO 2004/028825 A ist ein Sicherheitspapier zur Herstellung von Wertdokumenten, wie Banknoten oder dergleichen, beschrieben, das aus einem knitterbaren, mehrschichtigen Substrat umfassend mindestens eine Papierschicht und mindestens einer Folie besteht. Weiter ist ein Verfahren zur Herstellung eines derartigen Sicherheitspapiers offenbart.In WO 2004/028825 A is a security paper for the production of documents of value, such as banknotes or the like, described, which consists of a creaseable, multi-layered substrate comprising at least one paper layer and at least one film. Furthermore, a method for producing such a security paper is disclosed.

In DE 101 48 122 A1 sind Wertdokumente, wie Banknoten, Schecks, Pässe, Ausweiskarten oder dergleichen, beschrieben, bei denen wenigstens ein Kantenbereich zumindest teilweise mit einer Verstärkung versehen ist.In DE 101 48 122 A1 Value documents, such as banknotes, checks, passports, identity cards or the like, are described in which at least one edge region is at least partially provided with a reinforcement.

In WO 2005/036481 A1 sind eine Vorrichtung und ein Verfahren zur Prüfung von Wertdokumenten mit lumineszierenden Merkmalsstoffen beschrieben. Indem die Auswertung der erfaßten Lumineszenzstrahlung auf der Grundlage einer integrierten Lumineszenzmessung durchgeführt wird, welche durch eine Integration der gemessenen Lumineszenzstrahlung einer sich über die quer über das Wertdokument erstreckende Spur gewonnen wird, ist eine besonders leichte Erfassung und Unterscheidung auch von schwach leuchtenden Merkmalsstoffen ermöglicht.In WO 2005/036481 A1 An apparatus and a method for checking value documents with luminescent feature substances are described. By carrying out the evaluation of the detected luminescence radiation on the basis of an integrated luminescence measurement which is obtained by integrating the measured luminescence radiation of a track extending across the document of value, a particularly easy detection and differentiation of weakly luminous feature substances is made possible.

Deshalb ist es eine Aufgabe der vorliegenden Erfindung, ein alternatives blattförmiges Wertdokument mit lumineszierendem Merkmalsstoff bereitzustellen, welches nach Veraschung nicht ohne unverhältnismäßig hohen Aufwand für die Anfertigung von Fälschungen verwendet werden kann. Zudem soll die Herstellung eines solchen Wertdokuments angegeben werden.Therefore, it is an object of the present invention to provide an alternative sheet-shaped value document with luminescent feature substance which can not be used after incineration without disproportionately high expenditure for the production of counterfeits. In addition, the production of such a value document should be specified.

Diese Aufgaben werden durch die unabhängigen Ansprüche gelöst. Die weiteren Ansprüche beschreiben bevorzugte Ausgestaltungen.These objects are achieved by the independent claims. The further claims describe preferred embodiments.

Die vorliegende Erfindung geht somit von dem Ansatz aus, ein blattförmiges Wertdokument mit einem lumineszierenden Merkmalsstoff zu versehen, der sowohl vollflächig mit geringer Konzentration, als auch an bestimmten Teilflächen mit höherer Konzentration vorhanden ist.The present invention thus starts from the approach of providing a sheet-shaped value document with a luminescent feature substance which both over the entire surface with low concentration, as well as on certain sub-areas with higher concentration is present.

Der Merkmalsstoff ist in den Teilflächen mit höherer Konzentration in einer anderen Form vorhanden als in den umgebenden Bereichen mit geringer Konzentration.The feature substance is present in the higher concentration partial areas in a different form than in the low concentration surrounding areas.

So ist der lumineszierende Merkmalsstoff zum einen gleichmäßig in die Substratmasse eingebracht. Bei optischer Anregung des Substrats wird diese erste Einbringungsform mit einer geringen und gleichmäßigen Intensität der Lumineszenzstrahlung über die gesamte Papierfläche verbunden sein.For example, the luminescent feature substance is uniformly introduced into the substrate mass. Upon optical excitation of the substrate, this first injection form will be associated with a low and uniform intensity of the luminescent radiation over the entire paper surface.

Zum anderen ist dieser Merkmalsstoff auch in anderer Form, nämlich in Form von Melierfasern, Planchetten, lokal aufgeblasen, gesprüht oder in Form eines zusätzlichen Druckelements, an diskreten Stellen im Papier vorhanden. Bei der gleichen optischen Anregung des Papiers wird diese zweite Einbringungsform mit einer höheren Lumineszenzintensität an nur bestimmten lokalen Teilflächen der gesamten Papierfläche verbunden sein. Werden die erfindungsgemäßen Merkmalstoffe in eine Faser, Planchette o.ä. integriert, so können zusätzlich zu den Merkmalstoffen noch weitere Merkmalstoffe in diese Fasern eingebracht werden. Ein Sensor, der das Merkmal nachweist, das auch im Papier vorhanden ist, wird dann die erfindungsgemäße Variation des Merkmalsignals nachweisen, während ein Sensor für den zweiten Stoff hintergrundfrei nur das zweite Merkmal nachweisen wird.On the other hand, this feature substance is also present in another form, namely in the form of mottled fibers, planchettes, locally inflated, sprayed or in the form of an additional printing element, at discrete locations in the paper. With the same optical excitation of the paper, this second delivery form will be associated with a higher luminescence intensity at only certain local partial areas of the entire paper surface. Are the feature substances according to the invention in a fiber, planchette or similar. integrated, so in addition to the feature substances even more feature substances can be introduced into these fibers. A sensor which detects the feature which is also present in the paper will then detect the variation of the feature signal according to the invention, while a sensor for the second substance will detect only the second feature backgroundless.

Bei Beleuchtung mit einer die Lumineszenz des Wertdokuments anregenden Strahlung über eine Spur wird die gemessene Lumineszenzstrahlung somit eine gleichmäßig verteilte Grundintensität und einen oder mehrere nur an bestimmten Stellen der Spur vorhandene Peaks mit erhöhter Intensität aufweist.When illuminated with a luminescence of the value document stimulating radiation over a track, the measured luminescence thus has a uniformly distributed basic intensity and one or more existing only at certain points of the track peaks with increased intensity.

Die Kombination dieser beiden Einbringungsformen und die daraus resultierende Überlagerung einer gleichmäßigen Lumineszenzstrahlung mit geringer Intensität mit an definierten Stellen lokalen Peaks höherer Intensität im messbaren Lumineszenzspektrum des Wertdokuments hat den Vorteil, dass der Aufwand für einen Fälscher selbst dann unverhältnismäßig hoch wird, die richtige Kombination der beiden Einbringungsformen bei Fälschungen nachzumachen, wenn er in Besitz von Verbrennungsasche von Banknoten gelangt.The combination of these two forms of introduction and the resulting superimposition of a uniform luminescence radiation with low intensity with localized peaks of higher intensity in the measurable luminescence spectrum of the value document has the advantage that the expense for a counterfeiter is then disproportionately high, the right combination of the two Counterfeit forms of counterfeiting when it comes into possession of incinerated ash from banknotes.

Für Merkmale, deren Intensitäten durch Druckfarben reduziert werden, kann vorgesehen sein, daß die Druckfarben mit dem gleichen Merkmalstoff so versehen werden, daß die Reduktion durch die Druckfarbe ausgeglichen wird. Während das Merkmalsignal über die Banknote ohne zusätzliches Merkmal in der Druckfarbe in den Bereichen der Druckfarbe einbricht, wird das Merkmalsignal kann in der erfindungsgemäß ausgestatteten Banknote näherungsweise homogen sein, die Einbrüche durch z.B. Absorptionen der Druckfarbe können reduziert bzw. sogar überkompensiert werden.For features whose intensities are reduced by printing inks, it can be provided that the printing inks with the same feature substance be provided so that the reduction is compensated by the ink. While the feature signal on the banknote breaks without additional feature in the ink in the areas of the ink, the feature signal can be approximately homogeneous in the banknote equipped according to the invention, the burglaries by eg absorptions of the ink can be reduced or even overcompensated.

Die Echtheitsprüfung von solchen blattförmigen Wertdokumenten mit lumineszierendem Merkmalsstoff kann dadurch geprüft bzw. durchgeführt werden, dass Messwerte vom geprüften Wertdokument aufgenommen und ausgewertet werden, um festzustellen, ob der Merkmalsstoff sowohl vollflächig mit geringer Konzentration, als auch an bestimmten Teilflächen mit höherer Konzentration vorhanden ist.The authenticity check of such sheet-shaped value documents with luminescent feature substance can be checked or carried out by taking and evaluating measured values from the tested value document in order to determine whether the feature substance is present both over the whole area with low concentration and on certain partial areas with higher concentration.

Neben dieser einfachen Detektion der Existenz von Teilflächen mit höherer Konzentration können für einen selektiveren Nachweis auch die Eigenschaften der Verteilungen festgestellt werden. Bei statistischen Verteilungen sind die statistischen Kennzahlen der Verteilungen, z.B. Mittelwerte und Standardabweichungen, Quantile oder andere statistische Kenngrößen als zusätzliche Kriterien zur Überprüfung geeignet. Im Falle deterministischer Verteilungen können sowohl die Verteilungen gemäß der Vorgaben untersucht werden als auch die statistischen Abweichungen zu diesen.In addition to this simple detection of the existence of higher concentration sub-areas, the properties of the distributions can also be determined for more selective detection. For statistical distributions, the statistical measures of the distributions, e.g. Mean values and standard deviations, quantiles or other statistical parameters are suitable as additional criteria for review. In the case of deterministic distributions, it is possible to examine both the distributions according to the specifications and the statistical deviations from them.

Die Messwerte oder davon abgeleitete Größen können auch bei der Produktion der Banknoten aufgenommen und in einer Datenbank für spätere Überprüfungen hinterlegt werden. Alternativ können das Ergebnis der Überprüfung und/oder davon abgeleitete, z.B. verschlüsselte Größen auf der Banknote aufgebracht werden und stehen so für eine spätere Überprüfung zur Verfügung. Dies kann z.B. über Numerierwerke, ink-jet Druckverfahren, digitale Druckverfahren, Lasergestützte Ablation oder Veränderung geschehen.The measured values or quantities derived therefrom can also be included in the production of the banknotes and stored in a database for later checks. Alternatively, the result of the check and / or derived therefrom, eg encrypted sizes be applied to the banknote and are thus available for later review. This can be done, for example, by numbering machines, ink-jet printing methods, digital printing methods, laser-based ablation or modification.

Gemäß einer bevorzugten Weiterbildung des Wertdokuments ist der Merkmalsstoff auf oder in dem Wertdokument so verteilt, dass bei Beleuchtung des Wertdokuments mit einer die Lumineszenz des Merkmalsstoffs anregenden Strahlung eine über eine Spur gemessene Lumineszenzstrahlung eine gleichmäßig verteilte Grundintensität und einen oder mehrere nur an bestimmten Stellen der Spur vorhandene Peaks mit erhöhter Intensität aufweist. Unter einer Spur wird dabei insbesondere auch ein im Wesentlichen linearer Streifen auf dem Wertdokument, insbesondere von einem Rand des Wertdokuments zu einem anderen Rand desselben, verstanden, dessen Breite für eine Erfassung der Lumineszenzstrahlung aus dem Streifen mittels eines Detektors ausreicht.According to a preferred further development of the value document, the feature substance is distributed on or in the value document in such a way that when illuminating the value document with a radiation stimulating the luminescence of the feature substance, a luminescence radiation measured over a lane will have a uniformly distributed basic intensity and one or more only at certain points of the lane having existing peaks of increased intensity. In this case, a trace is also understood in particular to mean a substantially linear strip on the value document, in particular from one edge of the value document to another edge thereof, whose width is sufficient for detecting the luminescence radiation from the strip by means of a detector.

Weiter kann das Wertdokument verschiedene Teilflächen erhöhter Konzentration aufweisen, die sich hinsichtlich des Verlaufs der Intensität der Lumineszenzstrahlung bei Beleuchtung mit Anregungsstrahlung konstanter Intensität und/ oder hinsichtlich ihrer geometrischen Form unterscheiden.Furthermore, the value document can have different sub-areas of increased concentration, which differ in terms of the course of the intensity of the luminescence radiation when illuminated with excitation radiation of constant intensity and / or with respect to their geometric shape.

Darüber hinaus kann eine aus einem Verlauf der Intensität der Lumineszenzstrahlung des Merkmalstoffs bei Beleuchtung mit Anregungsstrahlung konstanter Intensität und/oder eine aus einer statistischen Verteilung des Verlaufs der Intensität der Lumineszenzstrahlung des Merkmalstoffs des Wertdokuments bei Beleuchtung mit Anregungsstrahlung konstanter Intensität abgeleitete Größe als Information auf das Wertdokument aufgebracht sein. Bei dem Herstellungsverfahren wird vorzugsweise eine aus einem Verlauf der Intensität der Lumineszenzstrahlung des Merkmalstoffs bei Beleuchtung mit Anregungsstrahlung konstanter Intensität und/oder eine aus einer statistischen Verteilung des Verlauf der Intensität der Lumineszenzstrahlung des Merkmalstoffs bei Beleuchtung mit Anregungsstrahlung konstanter Intensität abgeleitete Größe als Information auf das Wertdokument aufgebracht und/oder in einer externen Datenbank hinterlegt. Bei dem Prüfverfahren können dann vorzugsweise der Verlauf der Intensität der Lumineszenzstrahlung des Merkmalstoffs bei Beleuchtung mit Anregungsstrahlung konstanter Intensität und/oder Daten einer statistischen Verteilung des Verlauf der Intensität der Lumineszenzstrahlung des Merkmalstoffs des Wertdokuments bei Beleuchtung mit Anregungsstrahlung konstanter Intensität ermittelt und zur Bewertung der Echtheit oder des Zustands des Wertdokuments verwendet werden. Die Prüfeinrichtung ist dann vorzugsweise zu diesem Zweck ausgebildet.In addition, a variable derived from a course of the intensity of the luminescence radiation of the feature substance when illuminated with excitation radiation of constant intensity and / or a variable derived from a statistical distribution of the intensity of the luminescence radiation of the feature substance of the value document when illuminated with excitation radiation of constant intensity be applied as information on the document of value. In the production method, a variable derived from a course of the intensity of the luminescence radiation of the feature substance when illuminated with excitation radiation of constant intensity and / or a variable derived from a statistical distribution of the intensity of the luminescence radiation of the feature substance when illuminated with excitation radiation of constant intensity is preferably referred to as information on the value document applied and / or stored in an external database. In the test method, the course of the intensity of the luminescence radiation of the feature substance can then be determined with illumination with excitation radiation of constant intensity and / or data of a statistical distribution of the course of the intensity of the luminescence radiation of the feature substance of the value document when illuminated with excitation radiation of constant intensity and for the evaluation of authenticity or the state of the value document. The testing device is then preferably designed for this purpose.

Obwohl die Prüfvorrichtung in allen Banknotenbearbeitungsmaschinen, wie z.B. auch in Geldeinzahl-, Verkaufsautomaten oder Handprüfgeräten verwendet werden kann, wird im Folgenden anhand der Figur 1 exemplarisch der Einsatz in einer Banknotensortiermaschine 1 beschrieben, die in einer schematischen Darstellung von der Seite her gezeigt ist.Although the testing device can be used in all banknote processing machines, such as in money deposit, vending or hand testing, is in the following using the FIG. 1 the use in a bank note sorting machine 1 described by way of example, which is shown in a schematic representation from the side.

Die Banknotensortiermaschine 1 umfasst dabei in an sich bekannter Weise ein Eingabefach 3, in das zu prüfende Banknoten BN gestapelt eingegeben werden. Diese werden einzeln mittels eines Vereinzelers 4 vom Stapel abgezogen und entlang einer Transportstrecke 5 an einer Prüfvorrichtung 2 in Richtung T vorbeitransportiert. Die Prüfeinrichtung 2 weist dabei eine EDVgestützte Auswertungsrichtung 6 auf, die mit einer Beleuchtungseinrichtung 7 zur Anregung der lumineszierenden Merkmalsstoffe 15 im Banknotenpapier, einer Sensoreinrichtung 8 zur Erfassung der von der geprüften Banknote BN ausgehenden Lumineszenzstrahlung und einer Lichtschranke 10 verbunden ist, welche der Beleuchtungseinrichtung 7 und der Sensoreinrichtung 8 unmittelbar vorgeschaltet ist. Neben der Lichtschranke 10 können in der Transportstrecke 5 auch noch weitere nicht dargestellte Lichtschranken enthalten sein, um die Position der einzelnen Banknoten BN in der Transportstrecke 5 und in der Prüfvorrichtung 2 eindeutig bestimmen zu können. Weiterhin kann die Sensoreinrichtung 2 noch einen Zustandssensor 9, der insbesondere zur Bestimmung des Verschmutzungsgrades der Banknoten BN dient, aufweisen. Der Prüfeinrichtung 2 sind mehrere Weichen 11 nachgeordnet, um in Abhängigkeit von dem Ergebnis der Prüfung, das in der Auswertungseinrichtung 6 gewonnen wird, die Banknoten in eines von mehreren Fächern 12 auszugeben.In this case, the banknote sorting machine 1 comprises, in a manner known per se, an input compartment 3, into which banknotes BN to be checked are input, stacked. These are individually withdrawn from the stack by means of a separator 4 and transported along a transport path 5 on a test device 2 in the direction T. In this case, the test device 2 has an EDP-supported evaluation direction 6, which is connected to a lighting device 7 for exciting the luminescent feature substances 15 in the banknote paper, a sensor device 8 for detecting the luminescence radiation emitted by the checked banknote BN and a light barrier 10, which the illumination device 7 and the sensor device 8 is connected immediately upstream. In addition to the light barrier 10, further light barriers, not shown, may also be contained in the transport path 5 in order to be able to unambiguously determine the position of the individual banknotes BN in the transport path 5 and in the test apparatus 2. Furthermore, the sensor device 2 can still be a condition sensor 9, which is used in particular for determining the degree of soiling of the banknotes BN. The checking device 2 is followed by a plurality of switches 11, in order to output the bank notes into one of a plurality of compartments 12, depending on the result of the test, which is obtained in the evaluation device 6.

Die Banknotensortiermaschine 1 isf insbesondere durch den Aufbau und die Funktionsweise der Prüfvorrichtung 2 ausgezeichnet, die zur Erfassung von lumineszierenden Merkmalsstoffen in erfindungsgemäßen Banknoten BN dient.The banknote sorting machine 1 is distinguished in particular by the structure and the mode of operation of the checking device 2, which serves for detecting luminescent feature substances in banknotes BN according to the invention.

Vor der Erklärung dieser Prüfvorrichtung 2 sei zunächst auf die Herstellung und den Aufbau einer hiermit zu prüfenden erfindungsgemäßen Banknote BN eingegangen, wie sie beispielhaft in Figur 2 gezeigt ist.Before explaining this test apparatus 2, let us first consider the manufacture and construction of a banknote BN according to the invention to be tested here, as exemplified in FIG FIG. 2 is shown.

Die Banknote BN weist zum einen über die gesamte Banknotenfläche mit Länge L und Breite B mit einer geringen Flächendichte und Volumendichte gleichmäßig verteilt in die Papiermasse eingebrachte kreisförmig gezeichnete Pigmente 21 eines lumineszierenden Merkmalsstoffs auf. Weiterhin sind in der Papiermasse auch strichförmig symbolisierte Melierfasern 20 eingebracht, welche den gleichen lumineszierenden Merkmalsstoff aufweisen. Die Flächen- bzw. Volumendichte der Melierfasern über die gesamte Banknotenfläche bzw. das gesamte Banknotenvolumen betrachtet ist zwar geringer als diejenige der Pigmente, allerdings ist die lokale Konzentration des Merkmalsstoff in den Melierfasern 20 deutlich höher als die Konzentration des Merkmalsstoffs der Pigmente 21 in den umgebenden Bereichen der Banknotenfläche. Die Einbringung der Pigmente 21 und der Melierfasern 20 kann dabei in an sich bekannte Weise erfolgen.The banknote BN has, on the one hand, circularly drawn pigments 21 of a luminescent feature substance applied over the entire banknote surface of length L and width B with a low surface density and volume density evenly distributed in the paper pulp. Furthermore, in the paper pulp also symbolically shaped mottled fibers 20 are introduced, which have the same luminescent feature substance. Although the area or volume density of the mottled fibers over the entire banknote surface or the entire banknote volume is less than that of the pigments, the local concentration of the feature substance in the mottling fibers 20 is clearly higher than the concentration of the feature substance of the pigments 21 in the surrounding ones Areas of the banknote surface. The Incorporation of the pigments 21 and the mottling fibers 20 can be effected in a manner known per se.

Es sei betont, dass die Pigmente 21 bzw. die Melierfasern 20 nur der besseren Anschaulichkeit halber in Figur 2 hervorgehoben sind, an sich können diese Elemente auch für das bloße menschliche Auge nicht sichtbar oder weitgehend unsichtbar sein.It should be emphasized that the pigments 21 or the mottling fibers 20 are only for better clarity in FIG FIG. 2 As such, these elements can not be visible or largely invisible to the naked human eye.

Wesentlich ist, dass bei Beleuchtung mit einer die Lumineszenz des Merkmalsstoffs anregenden Strahlung die erste Einbringungsform des Merkmalsstoffs, d.h. hier die Pigmente 21 mit einer gleichmäßiger über die Banknotenfläche verteilten Intensität als die zweite Einbringungsform des gleichen Merkmalsstoffs, d.h. hier die Melierfasern 20, lumineszieren.It is essential that, when illuminated with a radiation exciting the luminescence of the feature substance, the first introduction form of the feature substance, i. Here, the pigments 21 having a uniform intensity distributed over the banknote surface as the second introduction form of the same feature substance, i. here the mottled fibers 20, luminesce.

Gerade diese erfindungsgemäße Eigenschaft echter Banknoten BN wird durch die Prüfvorrichtung 2 kalibriert. Hierzu wird die an der Beleuchtungseinrichtung 7 vorbeilaufende Banknote BN mittels der Beleuchtungseinrichtung 7 in Transportrichtung T entlang einer Spur S1 beleuchtet. Die Umrisslinie dieser Spur S1 ist in Figur 2 durch eine gestrichelte Linie S1 dargestellt. Zur Erfassung der von der beleuchteten Spur S1 ausgehenden Lumineszenzstrahlung der Banknote BN dient die Sensoreinrichtung 8. Die Messung erfolgt bei einer oder mehreren für die jeweilige Lumineszenzstrahlung charakteristischen Frequenzen und/oder Frequenzbändern.It is precisely this inventive property of genuine banknotes BN that is calibrated by the test device 2. For this purpose, the bank note BN passing by the illumination device 7 is illuminated by means of the illumination device 7 in the transport direction T along a track S1. The outline of this track S1 is in FIG. 2 represented by a dashed line S1. The sensor device 8 serves to detect the luminescence radiation of the banknote BN emanating from the illuminated track S1. The measurement takes place at one or more frequencies and / or frequency bands characteristic of the respective luminescence radiation.

In der unteren Hälfte von Figur 2 ist schematisch eine zugehörige Messkurve der Sensoreinrichtung 8 abgebildet. Im speziellen ist die gemessene Intensität I der Lumineszenzstrahlung einer geprüften Banknote BN über den sich in Richtung T erstreckenden Messort x aufgetragen. Es zeigt sich, dass die Messkurve ein Grundniveau der Intensität ib mit einzelnen lokalen Peaks z.B. der maximalen Intensität ic an bestimmten Messstellen hat. Die Intensität ib rührt dabei von der Lumineszenzstrahlung der Pigmente 21 und die einzelnen Peaks mit maximaler Intensität ic von der Lumineszenzstrahlung der Melierfasern 20 her, welche sich in der Messspur S1 befinden.In the lower half of FIG. 2 schematically an associated measurement curve of the sensor device 8 is shown. In particular, the measured intensity I of the luminescence radiation of a checked banknote BN is plotted over the measuring location x extending in the direction T. It turns out that the measurement curve has a basic level of intensity ib with individual local peaks, eg the maximum intensity ic at certain measuring points. The intensity ib stems from the luminescence radiation of the pigments 21 and the individual peaks of maximum intensity ic from the luminescence radiation of the mottling fibers 20, which are located in the measurement track S1.

In der Auswertungsrichtung 6 kann überprüft werden, ob bei gegebener Anregung die Messkurve einen für echte Banknoten charakteristischen Verlauf aufweist, d.h. beispielsweise die einzelnen Intensitäten ib und ic oder deren Verhältnis stimmt und/oder ob die lokalen Peaks an den richtigen Stellen der Banknoten BN entlang der Messspur S1 vorhanden sind. Sofern dies nicht der Fall ist, wird die geprüfte Banknote BN als falsch oder zumindest fälschungsverdächtig klassifiziert. Andernfalls kann die Banknote BN, vorbehaltlich des Ergebnisses anderer optionaler weiterer Messungen, als echt klassifiziert werden.In the evaluation direction 6 it can be checked whether, given the excitation, the measurement curve has a characteristic characteristic for real bank notes, i. for example, the individual intensities ib and ic or their ratio is correct and / or if the local peaks are present at the correct locations of the banknotes BN along the measuring track S1. If this is not the case, the checked banknote BN is classified as false or at least suspected of being forged. Otherwise, banknote BN may be classified as genuine, subject to the outcome of other optional further measurements.

Wenn eine solche echte Banknote BN wegen zu großer Abnutzung aus dem Umlauf gezogen und vernichtet wird und ein Fälscher Zugriff auf die Verbrennungsasche der Banknote BN erhält und zum Anfertigen von Fälschungen verwendet, so kann erwartet werden, dass eine solche Fälschung üblicherweise so ausgestaltet sein wird, wie es in Figur 3 abgebildet ist.If such a genuine banknote BN is withdrawn from circulation due to excessive wear and destroyed and a counterfeiter obtains access to the incineration ash of the banknote BN and uses it to make counterfeits, it can be expected that such a counterfeit will usually be designed in such a way that as it is in FIG. 3 is shown.

Die gefälschte Banknote BNF wird über die gesamte Fläche mit Länge L und Breite B gleichmäßig verteilt in die Papiermasse eingebrachte Pigmente 21 des lumineszierenden Merkmalsstoffs aufweisen, den der Fälscher aus der Verbrennungsasche der echten Banknoten BN gewonnen hat. Das Reproduzieren der vorgegebenen Verteilung der Melierfasern 20, die zu lokalen Peaks der Messung an vorbestimmten Stellen der Banknote BN führt, ist für den Fälscher nicht ohne unverhältnismäßig hohen Aufwand durchführbar.The counterfeit banknote BNF will have over the entire surface of length L and width B evenly distributed in the pulp introduced pigments 21 of the luminescent feature substance, which the counterfeiter has gained from the combustion ash of the genuine banknotes BN. Reproducing the predetermined distribution of the mottled fibers 20, which leads to local peaks of the measurement at predetermined locations of the banknote BN, can not be carried out by the forger without disproportionately high outlay.

Deshalb hat die bei denselben Messbedingungen wie nach Figur 2 gemessene Kurve der Lumineszenzintensität I ein weitgehend gleichförmiges Niveau ia ohne lokale Peaks hoher Intensität, wie sie bei echten Banknoten BN von den Melierfasern 20 herrühren. Je nach Flächen- bzw. Volumendichte der Pigmente 21 kann die Intensität ia der Fälschung BNF dabei höher oder niedriger als das Intensitäts-Grundniveau ib der echten Banknoten BN sein.Therefore it has the same measurement conditions as below FIG. 2 measured luminescent intensity curve I a substantially uniform level generally without high intensity local peaks, as they come from the mottling fibers 20 in real banknotes BN. Depending on the surface or volume density of the pigments 21, the intensity ia of the counterfeit BNF can be higher or lower than the intensity base level ib of the genuine banknotes BN.

Aufgrund des Unterschieds der Messkurve der Fälschung BNF (Figur 3, unten) zur zu erwartenden Messkurve echter Banknoten BN (Figur 2, unten) kann somit in der Auswertungsrichtung 6 das geprüfte Dokument BNF als Fälschung klassifiziert werden.Due to the difference of the trace of the counterfeit BNF ( FIG. 3 , below) to the expected measurement curve of genuine banknotes BN ( FIG. 2 , bottom) can thus be classified in the evaluation direction 6, the examined document BNF as a forgery.

Vorstehend wurde ein spezielles Beispiel der Erfindung beschrieben. Hierzu sind selbstverständlich zahlreiche Alternativen denkbar, von denen einige exemplarisch beschrieben werden.In the above, a specific example of the invention has been described. Of course, numerous alternatives are conceivable for this purpose, some of which are described by way of example.

Zudem müssen die unterschiedlichen Einbringungsformen nicht zwingend in Melierfasern 20 bestehen. Diese können auch in Planchetten oder Aufdrucken bestehen.In addition, the different forms of introduction do not necessarily have to consist of mottling fibers 20. These can also exist in planchettes or imprints.

Während vorstehend beschrieben wurde, dass der gleiche Merkmalsstoff mit unterschiedlichen Konzentrationen ins Papier eingebracht wird, können an sich auch unterschiedliche Merkmalsstoffe mit unterschiedlicher Konzentration verwendet werden, zumindest solange sich die Messwerte der Lumineszenzstrahlung dieser unterschiedliche Merkmalsstoffe bei der Prüfung mit einer üblichen Prüfvorrichtung 2 nicht signifikant unterscheiden.While it has been described above that the same feature substance with different concentrations is introduced into the paper, it is also possible to use different feature substances with different concentrations per se, at least as long as the measured values of the luminescence radiation of these different feature substances do not differ significantly in the test with a conventional test device 2 ,

Weiterhin kann auch vorgesehen sein, dass die unterschiedlichen Einbringungsformen 20, 21 unterschiedliche Merkmalsstoffe oder Merkmalsstoffkombinationen aufweisen. So können z.B. die Pigmente 21 aus einem ersten Merkmalsstoff bestehen und die Melierfasern 20 aus einer Kombination dieses ersten und eines anderen zweiten Merkmalsstoffs. Diese Möglichkeit nicht nur einen, sondern mehrere unterschiedliche Merkmalsstoffe in gegebenenfalls auch unterschiedlichen Kombinationen vorzusehen, kann die Anzahl der möglichen Codierungen von Merkmalseigenschaften deutlich erhöhen.Furthermore, it can also be provided that the different introduction forms 20, 21 have different feature substances or feature substance combinations. For example, the pigments 21 can consist of a first feature substance and the mottling fibers 20 of a combination of this first and another second feature substance. This possibility not just one, but several Provide different feature substances in possibly also different combinations, can significantly increase the number of possible codes of feature properties.

In diesem Sinne kann auch eine räumliche Codierung erfolgen, indem es z.B. mehrere unterschiedliche und nachprüfbare räumliche Anordnungen der Melierfasern 20 und/oder Pigmente 21 gibt. Wenn zum Codieren beispielsweise drei unterschiedliche Merkmalsstoffe vorhanden und vier unterschiedliche räumliche Anordnungen der Merkmalsstoffe in den unterschiedlichen Einbringungsformen möglich sind, so stehen bereits 34, also 81 verschiedene Codierungen zur Verfügung. Mit Hilfe des sogenannten "Wilcox"-Verfahren können Melierfasern sehr platziert in das Banknotenpapier eingebracht werden. Hierdurch kann die Anzahl der räumlichen Codierungen der Merkmalsstoffe noch weiter erhöht werden.In this sense, a spatial coding can be carried out by, for example, there are several different and verifiable spatial arrangements of the mottling fibers 20 and / or pigments 21. If, for example, three different feature substances are available for coding and four different spatial arrangements of the feature substances in the different delivery forms are possible, then there are already 3 4 , ie 81 different codes available. With the help of the so-called "Wilcox" method, mottled fibers can be placed very placed in the banknote paper. As a result, the number of spatial codes of the feature substances can be further increased.

Es kann auch vorgesehen sein, daß verschiedene Elemente, z.B. Melierfasern, Planchetten, etc. verwendet werden, die den gleichen (oder mehrere) Merkmalstoffe in verschiedenen Konzentrationen enthalten. Auf diese Weise läßt sich ebenfalls eine Kodierung darstellen. Es kann dabei vorgesehen sein, daß die verschiedenen Elemente lokalisiert oder auch statistisch verstreut in die Banknote integriert werden.It can also be provided that different elements, e.g. Melierfasern, planchettes, etc. are used, which contain the same (or more) feature substances in different concentrations. In this way, can also represent a coding. It can be provided that the various elements are localized or statistically dispersed in the banknote integrated.

Die Messung der Lumineszenzstrahlung kann schließlich z.B. auch nicht nur entlang einer, sondern auch entlang mehrer Spuren und/oder nur an mehreren diskreten Stellen entlang einer Spur erfolgten.The measurement of the luminescence radiation may finally be made e.g. not only along one but also along several tracks and / or only at several discrete points along a track.
