Description
Die Erfindung betrifft elektrisch leitende Sicherungsmerkmale für Wertpapiere, Banknoten und Dokumente, welche beim Papierherstellungsprozeß durch unterschiedliche technologische Prozesse eingebracht werden.The invention relates to electrically conductive security features for securities, Banknotes and documents in the paper making process different technological processes are introduced.
Bekannt sind Spezialpapiere, welche Identifikationsmerkmale zum Fälschungsschutz beinhalten. Diese werden während des Papierherstellungsprozesses integriert. So werden zum Beispiel lichtaktive Merkmalsstoffe eingebaut. Einige lichtaktiven Merkmalsstoffe sind heute am Markt erhältlich, so daß Fälscher in der Lage sind, diese bereits bekannten Sicherheitsmerkmale nachzustellen. Es werden z. B. Sicherheitsmerkmale im UV- Spektralbereich nachgestellt. Diese Nachstellungen haben eine erhebliche Wirkung auf die Fälschungssicherheit.Special papers are known, which identification features for Protection against counterfeiting. These are used during the Integrated paper manufacturing process. For example, they become light active Feature substances incorporated. Some light-active feature substances are on the market today available so that counterfeiters are able to use these already known Recreate security features. There are e.g. B. Security features in UV Adjusted spectral range. These reenactments have a significant impact on counterfeit protection.
Desweiteren werden optische Merkmale in Form von Wasserzeichen in diese Papiere eingebracht. Das Wasserzeichen wird gegenwärtig nur unbedeutend nachgestellt. Bekannte Fälschungen beziehen sich auf das Bedrucken der Papiere mit Wasserzeichen ähnlichen Darstellungen. Diese sind jedoch mit Hilfsmitteln oder im Durchlicht bzw. im UV-Bereich erkennbar. Furthermore, there are optical features in the form of watermarks Papers introduced. The watermark is currently becoming insignificant adjusted. Known counterfeits relate to the printing of the papers with representations similar to watermarks. However, these are with aids or recognizable in transmitted light or in the UV range.
Eine weitere Möglichkeit der Sicherung von Papieren ist die Integration von Sicherheitsfäden oder von Sicherheitsbändern. Diese Sicherheitsfäden, Sicherheitsbänder sind in der Regel elektrisch leitend. Die Sicherheitsfäden oder Sicherheitsbänder bestehen vorwiegend aus einer metallisierten Folie, welche partiell mit Buchstaben oder Zahlen bzw. Symbolen demetallisiert, oder ausgestanzt wurden. Diese zusätzlichen Merkmale sind als optische Merkmale ausgebildet und dienen zur optischen Absicherung und als technologische Hürde für den Fälscher. Die Fäden selbst werden mittels bekannter kapazitiver Sensoren detektiert. Hierbei wird die elektrische Leitfähigkeit für einen bestimmten Abschnitt des Fadens gemessen. Dabei handelt es sich um die Feststellung der Präsenz. Gegenwärtig werden durch Fälscher auch diese Sicherheitsfäden nachgestellt.Another way of securing paper is to integrate Security threads or security tapes. These security threads, Security tapes are generally electrically conductive. The security threads or Security tapes mainly consist of a metallized film, which partially demetallized with letters or numbers or symbols, or punched out were. These additional features are designed as optical features and serve as optical security and as a technological hurdle for the counterfeiter. The threads themselves are detected using known capacitive sensors. Here is the electrical conductivity for a specific section of the thread measured. This is the determination of the presence. These security threads are currently being reproduced by counterfeiters.
Diese Nachstellungen werden durch Aufbringen von Heißklebefolien oder durch Auftragen von metallischen Tinten durchgeführt. Für den Betrachter im schnellen Banknotenverkehr sind diese Nachstellungen schwer erkennbar. Außerdem sind derartige Nachstellungen für die Bankautomaten nicht immer detektierbar. Hochsensible kapazitive Sensoren können innerhalb geringer Meßtoleranzen jedoch einen Teil dieser Fälschungen detektieren.These re-enactments are made by applying hot adhesive film or by Apply metallic inks. For the viewer quickly These reenactments are difficult to detect in banknote transactions. Also are such reenactments for the ATMs are not always detectable. Highly sensitive capacitive sensors can operate within small measurement tolerances however, detect some of these counterfeits.
Aufgabe der Erfindung ist es, den elektrischen leitenden Sicherheitsfäden bzw. elektrisch leitenden Sicherheitsbändern als benutzeraktive Sicherheitsmerkmale, eine zusätzliche Referenzprüfung und oder als selbständige Prüfzonen mittels Integration von elektrisch leitenden Merkmalsstoffen innerhalb des Papieres und Prüfung derselben, mittels bekannter kapazitiver Scannersensoren zu schaffen. The object of the invention is the electrically conductive security threads or electrically conductive security tapes as user-active security features, an additional reference test and or as independent test zones using Integration of electrically conductive feature substances within the paper and Testing the same, using known capacitive scanner sensors.
Die Erfindung wird im folgenden anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert und beschrieben. Die den Zeichnungen und der Beschreibung zu entnehmenden Merkmale, können bei anderen Ausführungsformen der Erfindung einzeln für sich oder zu mehreren in beliebiger Kombination, Anwendung finden.The invention is described below with reference to the drawings Exemplary embodiments explained and described in more detail.

Merkmalsstoffe mit elektrischer Leitfähigkeit bestehen in der Regel aus Feststoffen, wie Pigmenten in Stabform oder unregelmäßiger Form. Weiterhin sind elektrisch leitende Polymere in unterschiedlichen Ausführungen bekannt.Feature substances with electrical conductivity usually consist of solids, like pigments in rod form or irregular form. Furthermore, are electrical Conductive polymers known in different designs.
Das Vorhandensein von diesen unterschiedlichen Erscheinungsformen ermöglicht eine Vielzahl technologischer Möglichkeiten der Integration des Merkmalsstoffes in das Papier.The presence of these different manifestations enables a variety of technological possibilities for the integration of the feature substance in the paper.
In diesem Ausführungsbeispiel wird die Herstellung von Spezialpapier mit elektrisch leitenden Pigmenten als Merkmalsstoff dargestellt. In der Maschinenbütte (8) wird der Papierstoff mit dem Merkmalsstoff gemischt und unter ständigem Rühren als homogene Suspension gehalten. Bei festen Merkmalspigmenten verwendet man vorzugsweise 10% des Papierfeststoffgehaltes als Zugabemenge. Je nach Detektionsart kann diese anteilige Menge variieren. In this embodiment, the production of special paper with electrically conductive pigments is shown as a feature substance. The paper stock is mixed with the feature stock in the machine chest ( 8 ) and kept under constant stirring as a homogeneous suspension. For solid feature pigments, 10% of the paper solids content is preferably used as the addition amount. This proportionate amount can vary depending on the type of detection.
Bei Verwendung elektrisch leitender Polymere ergibt sich der Vorteil, daß eine gute Verträglichkeit zu anderen Materialien besteht. Die Integration in den Papierstoff ist wesentlich unkomplizierter als bei festen Stoffen, da elektrisch leitende Polymere auch als Dispersion vorkommen. Die benötigte Konzentration gestattet eine nahezu transparente elektrisch leitende Markierung.When using electrically conductive polymers there is the advantage that a good Compatibility with other materials exists. The integration into the paper stock is much more straightforward than with solid materials because of the electrically conductive polymers also occur as a dispersion. The required concentration almost allows one transparent electrically conductive marking.
Die Detektion von homogen eingebrachten Merkmalsstoffen (6) wird mittels kapazitiven Sensors (11) realisiert. Hierbei kann nur die Präsenz des Merkmales nachgewiesen werden.The detection of homogeneously introduced feature substances ( 6 ) is realized by means of capacitive sensors ( 11 ). Only the presence of the characteristic can be verified here.
Verwendet man diese homogene Version als Referenzmerkmal zu dem elektrisch leitenden Sicherheitsfaden, so ist es erforderlich, daß ein Merkmalsstoff mit einer Leitfähigkeit von größer oder kleiner 35% der Leitfähigkeit des Sicherheitsfadens eingesetzt wird. Somit detektiert der Scannersensor (11) die Fläche des Prüfobjektes auf die homogene Beschaffenheit und als Referenz hierzu die Präsenz eines Sicherheitsfadens mit vorgegebenen elektrischen Leiteigenschaften.If this homogeneous version is used as a reference feature for the electrically conductive security thread, it is necessary that a feature substance with a conductivity of greater or less than 35% of the conductivity of the security thread is used. The scanner sensor ( 11 ) thus detects the surface of the test object for the homogeneous nature and, as a reference, the presence of a security thread with predetermined electrical conductivity properties.
In Fig. 6 wird dargestellt, wie das Blattgut den Sensor (11) passiert und dabei das elektrische Signal am Sensor erzeugt wird.In Fig. 6 it is shown how the sheet material passes the sensor ( 11 ) and the electrical signal is generated at the sensor.
Das Blattgut passiert zuerst optische Sensoren (13), welche den kapazitiven Scannersensor (11) aktivieren. The sheet material first passes through optical sensors ( 13 ) which activate the capacitive scanner sensor ( 11 ).
Der homogen eingebrachte Merkmalsstoff (6) erzeugt nun ein Signalbild (23) in der Zeitfolge 1-3, bei Zeitpunkt 4 überstreift der Sicherheitsfaden (15) den kapazitiven Scannersensor (11). Beim Sicherheitsfaden entsteht ein wesentlich größeres Signal, da in diesem Fall der Sicherheitsfaden über eine höhere Leitfähigkeit verfügt als der gedruckte Merkmalsstoff. In der Zeitfolge 5-7 wird das gleiche Signalbild wie in der Zeitfolge 1-3 erzeugt. Mittels Controller werden die Signalbilder verglichen und ausgewertet.The homogeneously introduced feature substance ( 6 ) now generates a signal image ( 23 ) in the time sequence 1-3 , at time 4 the security thread ( 15 ) slips over the capacitive scanner sensor ( 11 ). A significantly larger signal is produced with the security thread, since in this case the security thread has a higher conductivity than the printed feature substance. In the time sequence 5-7 , the same signal picture as in the time sequence 1-3 is generated. The signal images are compared and evaluated using a controller.
In einem zweiten Beispiel (Fig. VII) wird eine weitere Möglichkeit der homogenen Merkmalsintegration (6) im Papierstoff dargestellt. Hierbei werden weitere Codierungen durch Stoffdichteänderung (9) erreicht.In a second example ( Fig. VII) a further possibility of homogeneous feature integration ( 6 ) in the paper stock is shown. Here, further coding is achieved by changing the material density ( 9 ).
Der technologische Vorgang ist bis zur Bildung der Papierstoffbahn mit dem ersten Ausführungsbeispiel identisch. Die Weiterbearbeitung der Papierstoffbahn erfolgt durch das Prägen von Wasserzeichen.The technological process is until the formation of the paper web with the first Embodiment identical. The paper web is further processed by embossing watermarks.
Der Vorgang der Wasserzeichenherstellung erfolgt über eine mechanische Bearbeitung der Papierstoffbahn. Hierbei wird mittels Prägewalze (5) ein Abdruck auf der Papierstoffbahn erzeugt. Diese Prägewalze besteht aus einer Trägerwalze mit aufgesetzten Prägesegmenten (25). Diese Prägesegmente wiederum entsprechen der bildlichen Darstellung des Wasserzeichens. Der Abdruck der Prägesegmente (25) auf der Papierstoffbahn entspricht der bildlichen Darstellung auf der Prägewalze. Eine derartige mechanische partielle Behandlung der Papierstoffbahn bewirkt eine Stoffdichteänderung im Bereich des Wasserzeichens (9), mit einer abdrucktypischen elektrisch leitenden Struktur (9). Diese Änderung der elektrischen Leitfähigkeit im Prägebereich entspricht der bildlichen Darstellung des Prägesegmentes (25). The watermarking process is carried out by mechanical processing of the paper web. An impression is made on the paper web by means of embossing roller ( 5 ). This embossing roller consists of a carrier roller with attached embossing segments ( 25 ). These embossed segments correspond to the pictorial representation of the watermark. The impression of the embossing segments ( 25 ) on the paper web corresponds to the pictorial representation on the embossing roller. Such a mechanical partial treatment of the paper web causes a change in consistency in the area of the watermark ( 9 ) with an electrically conductive structure ( 9 ) typical of the impression. This change in the electrical conductivity in the stamping area corresponds to the pictorial representation of the stamping segment ( 25 ).
Führt man nun das so erzeugte Blattgut über einen kapazitiven Scannersensor (11), so erhält man ein Signalbild (23) für den Prägebereich (9) entsprechend der bildlichen Darstellung und der Scannerauflösung.If the sheet material produced in this way is then passed over a capacitive scanner sensor ( 11 ), a signal image ( 23 ) for the embossing area ( 9 ) is obtained in accordance with the visual representation and the scanner resolution.
In Fig. 7 wird dargestellt, wie eine Banknote im Querformat den Scannersensor (11) passiert und wie das Signalbild (23) beim Überstreifen des Blattgutes mit homogen eingebrachtem Merkmalsstoff (6) und anschließend erzeugten Wasserzeichen (9) entsteht. In der Darstellung aktivieren optische Sensoren (13) den kapazitiven Scannersensor (11). Beim Überstreifen des Blattgutes über den Sensor entsteht ein gleichmäßiges Signalbild an den Kanälen 1, 2, 6, 8, 9, 10 über den Zeitraum der Banknotenpräsenz. An den Scannerkanälen 3, 4, 5 entsteht entsprechend der partiellen stofflichen Änderung und der damit verbundenen Änderung der partiellen elektrischen Leitfähigkeit ein Signalbild. FIG. 7 shows how a banknote in landscape format passes the scanner sensor ( 11 ) and how the signal image ( 23 ) is created when the sheet material is slipped over with homogeneously introduced feature substance ( 6 ) and the watermark ( 9 ) subsequently generated. In the illustration, optical sensors ( 13 ) activate the capacitive scanner sensor ( 11 ). When the sheet material is slipped over the sensor, a uniform signal image is created on channels 1 , 2 , 6 , 8 , 9 , 10 over the period of the banknote presence. A signal image is generated on the scanner channels 3 , 4 , 5 in accordance with the partial material change and the associated change in the partial electrical conductivity.
Verwendet man Bariumsulfat als Merkmalsstoff, so erreicht man eine zusätzliche Codierung im optischen Bereich, denn dieser Stoff ist Infrarot absorbierend. Die Sensoranordnung des kapazitiven Scannersensors wird nun mit einem optischen Scannersensor kombiniert. In Fig. 7 wird dargestellt, wie die Anordnung beider Sensoren realisiert wird.If barium sulfate is used as a feature substance, additional coding is achieved in the optical range, because this substance is infrared absorbing. The sensor arrangement of the capacitive scanner sensor is now combined with an optical scanner sensor. FIG. 7 shows how the arrangement of both sensors is realized.
Ein drittes Ausführungsbeispiel stellt eine Version der Herstellung von partiellen Merkmalsstoffprüfzonen dar.A third embodiment represents a version of the production of partial Characteristic substance test zones.
Nach der Bildung der konventionellen Papierbahn wird mittels Prägewalzen ein Wasserzeichen (24) erzeugt. Bei dieser Wasserzeichenerzeugung werden die Merkmalsstoffpigmente bzw. der Merkmalsstoff als Dispersion, auf die Papierbahn übertragen. In Fig. 8 wird dieser Vorgang dargestellt. After the conventional paper web has been formed, a watermark ( 24 ) is generated by means of embossing rollers. During this watermark generation, the feature substance pigments or the feature substance as a dispersion are transferred to the paper web. This process is shown in FIG .
Eine Merkmalsübertragungswalze (7) wird durch einen Vorratsbehalter (16) mit Merkmalsstoff gespeist. Diese Merkmalsstofftransportwalze wiederum läuft gegen die Prägewalze (5), wobei der Merkmalsstoff auf das Prägesegment (25) übertragen wie. Da der Umfang der Prägewalze dem Abstand der Wasserzeichen (24) zueinander entspricht, ist die Herstellung dieser elektrisch leitender Wasserzeichen (24) an der Endlosbahn möglich.A feature transfer roller ( 7 ) is fed with feature substance by a storage container ( 16 ). This feature substance transport roller in turn runs against the embossing roller ( 5 ), the feature substance being transferred to the embossing segment ( 25 ) as. Since the circumference of the embossing roller corresponds to the distance of the watermarks ( 24 ) from one another, it is possible to produce these electrically conductive watermarks ( 24 ) on the endless web.
In Fig. VIIIa wird die Entstehung des Signalbildes am Scannersensor (11) dargestellt.The formation of the signal image on the scanner sensor ( 11 ) is shown in Fig. VIIIa.
In einem vierten Beispiel wird dargestellt, wie partieller Merkmalsstoffauftrag auf die Papierbahn mittels Tropfeinrichtung bzw. mittels Auslaufrohren (17), welche sich genau positioniert über der Papierstoffbahnbahn befinden, realisiert wird.A fourth example shows how partial feature substance application to the paper web is realized by means of a drip device or by means of outlet pipes ( 17 ), which are positioned exactly above the paper web path.
Fig. 1 und 2 stellen dar, wie mittels einer zielgenauen, mehrfach angeordneten elektronisch gesteuerten Dosiereinrichtung (17/19) ein partieller Merkmalsstoffauftrag, Merkmalsstoffintegration in die Papierstoffbahn, erfolgt. Einerseits kann linienförmig (14a) aufgetragen werden, zum anderen kann diskontinuierlich linenförmig (14b) oder punktuell (14c) aufgetragen werden. Somit erhalt man beim Schneiden der Papierbahn zu Blattgut, partielle Merkmalszonen. Diese können über die gesamte Blattbreite oder Blattlänge verlaufen bzw. abschnittsweise in der Blattbreite bzw. Blattlänge vorhanden sein. Die Breite der Linien, bzw. der Linienabschnitte ist der Scannerauflösung angepaßt. Vorzugsweise ist die Breite 2 mm. In Fig. 10 werden die Signalbilder für die Prüfung der kontinuierlichen und diskontinuierlichen Merkmalslinien im Blattgut dargestellt. Optische Sensoren (13) aktivieren den Scannersensor (11) beim Überstreifen des Blattgutes. Erreicht der Merkmalsstreifen den Sensor so entsteht das Signalbild 14aa, 14bb oder 14cc. Gleiche Signalbilder entstehen auch bei linienformigem, oder diskontinuierlichem Linienauftrag durch Streichen auf die Papierbahn. Fig. 1 and 2 illustrate how by means of a targeted, multiple arranged electronically controlled metering device (17/19) is a partial feature substance order feature substance integration into the paper web takes place. On the one hand, line-shaped ( 14 a) can be applied, on the other hand discontinuous linen-shaped ( 14 b) or spot ( 14 c) can be applied. This gives you partial feature zones when cutting the paper web into sheet material. These can run over the entire sheet width or sheet length or can be present in sections in the sheet width or sheet length. The width of the lines or line sections is adapted to the scanner resolution. The width is preferably 2 mm. In Fig. 10, the signal images for the examination of continuous and discontinuous characteristic lines are shown in the sheet material. Optical sensors ( 13 ) activate the scanner sensor ( 11 ) when the sheet material is slipped on. If the feature strip reaches the sensor, the signal pattern 14 aa, 14 bb or 14 cc is produced. The same signal images are also created in line-shaped or discontinuous line application by swiping on the paper web.
