Abstract

To distinguish original prints from copies, a method is proposed which allocates fine invisible markings, which cannot be reproduced by copying processes, to the original print. The markings themselves can only be detected by optical aids.

Description

Die Erfindung betrifft ein Verfahren zur Kennzeichnung von Originaldrucken zur Unterscheidung gegenüber von Kopien.The invention relates to a method for marking original prints to distinguish them from copies.

Für viele Anwendungen in der Drucktechnik ist es erforder­lich, das Original von Kopien zu unterscheiden, so bei­spielsweise bei Gebühren- oder Wertstempelungen. Mittels moderner Kopierverfahren können derartige Drucke, zumal dann, wenn sie auf Haftstreifen gedruckt sind, wie z. B. bei Frankiereinrichtungen, beliebig vervielfältigt werden und sind praktisch nicht unterscheidbar vom Original.For many applications in printing technology, it is necessary to distinguish the original from copies, for example in the case of fee or value stamps. Using modern copying processes, such prints, especially if they are printed on adhesive strips, such as. B. franking devices, are reproduced as desired and are practically indistinguishable from the original.

Für Dokumente ist bekannt, Warnmarkierungen mitzudrucken, die optisch nicht sichtbar sind, indem sie von gleicher Farbe und Dichte des Hintergrundes sind und durch andere Drucke oder Musterungen überlagert werden (DE-OS 34 19 859). Erst in der Kopie werden die Warnmarkierungen sichtbar.For documents it is known to include warning markings that are not visually visible, because they are of the same color and density of the background and are overlaid by other prints or patterns (DE-OS 34 19 859). The warning marks are only visible in the copy.

Weiterhin ist bekannt, für den Originaldruck ein Sicher­heitspapier zu verwenden, dessen Farbdichte der Sicherungs­markierungen unterhalb der Reproduziergrenze von Farb­kopierern liegt (DE-PS 28 05 146).It is also known to use security paper for the original print, the color density of the security markings being below the reproducibility limit of color copiers (DE-PS 28 05 146).

Derartige Verfahren sind jedoch aufwendig und teilweise nicht anwendbar, wenn direkte Aufdrucke auf unterschied­liche Vorlagen verlangt sind, wie z. B. Briefe oder ver­schiedene Belegvordrucke.However, such methods are complex and sometimes not applicable when direct prints on different templates are required, such as. B. letters or various voucher forms.

Der Erfindung lag die Aufgabe zugrunde, für letztgenannte Zwecke des direkten Aufdruckes von Wertstempelungen auf verschiedene Druckvorlagen ein Sicherungsverfahren zu schaffen, das Kopien der Originaldrucke bzw. Fälschungen erkennbar werden läßt.The invention had for its object to provide a security method for the latter purposes of directly printing value stamps on various printing templates, which makes copies of the original prints or forgeries recognizable.

Diese Aufgabe ist dadurch gelöst, daß im Originaldruck für das Auge nicht sichtbare, feine Markierungen mitge­druckt werden, die durch handelsübliche Kopierer nicht reproduzierbar sind.This object is achieved in that fine markings which are invisible to the eye and which cannot be reproduced by commercially available copiers are also printed in the original print.

Es werden im Original feine, für das Auge nicht sichtbare Markierungen, wie Linien, Raster oder Musterungen, mit­gedruckt. Diese Markierungen sind nur mit Hilfe optischer Geräte erkennbar, z. B. Lupen. Somit sind sie auch für jeden normalen Kopierer unsichtbar und nicht reproduzier­bar. Damit ist bei Verdacht der Fälschung bzw. der ab­sichtlichen Ausgabe einer Kopie als Original eine einfache Kontrolle ermöglicht. Die Markierungen werden vorzugs­weise über die Druckvorrichtung erzeugt. So sind auf einfache Art in beliebiger Feinheit derartige Markierungen über die Druckersteuerung, z. B. eines Druckkopfes in Frankiermaschinen, herstellbar.Fine markings, such as lines, grids or patterns, which are not visible to the eye, are also printed in the original. These markings can only be recognized with the help of optical devices, e.g. B. magnifying glasses. They are therefore invisible to any normal copier and cannot be reproduced. This makes it easy to check if the counterfeit is suspected or if a copy is deliberately given as an original. The markings are preferably generated via the printing device. So in a simple way in any fineness such markings on the printer control, for. B. a printhead in franking machines.

Eine andere Variante der Erzeugung unsichtbarer Mar­kierungen ist deren Einbringen oder Aufbringen in oder auf das zu bedruckende Material vor dem Druck. Dieses kann bei Druckern mit Druckfarben oder Tinten durch ein entsprechend vorgesetztes Druckwerk für feine Markierungen vorgenommen werden. Oder die Druckvorlage wird bei deren Herstellung bereits mit entsprechenden Markierungen ver­sehen, beispielsweise bei Briefumschlägen oder speziellen Papierstreifen für Streifengeber von Frankier- und/oder Wertstempelmaschinen innerhalb des Papiersubtrats.Another variant of the production of invisible markings is their introduction into or onto the material to be printed before printing. For printers with printing inks or inks, this can be done by a corresponding printing unit for fine markings. Or the print template is already provided with appropriate markings during its manufacture, for example in the case of envelopes or special paper strips for strip dispensers of franking and / or stamping machines within the paper substrate.

Eine weitere Variante ist die Einbringung der Markierungen in das Farbband.Another variant is the introduction of the markings into the ribbon.
