Abstract

Zur Unterscheidung von Originaldrucken von Kopien wird ein Verfahren vorgeschlagen, bei dem dem Druckmedium Substanzen zugefügt werden, die für das Auge nicht sichtbare Markierungen erzeugen, welche nur durch spezielle Lesegeräte erkennbar sind.In order to distinguish between original prints and copies, a method is proposed in which substances are added to the print medium which produce markings which are not visible to the eye and which can only be recognized by special reading devices.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Unter­scheidung von Originaldrucken von Kopien.The invention relates to a method for distinguishing original prints 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 gelöst durch Zufügen von Substanzen zum Druckmedium, die im Originaldruck für das Auge und damit für Kopierzwecke unsichtbare Markierungen erzeugen.This object is achieved by adding substances to the printing medium which, in the original print, produce markings which are invisible to the eye and thus for copying purposes.

Bei einem Farbband als Druckmedium überziehen Markier­ungen aus der nicht sichtbaren Substanz das Farbband als Linien, Raster oder Musterungen und gelangen, z. B. bei Frankier- oder Wertstempelungen, mit dem Abdruck auf die Vorlage.In the case of an ink ribbon as a printing medium, markings from the invisible substance cover the ink ribbon as lines, grids or patterns and arrive, for. B. with franking or value cancellations, with the imprint on the template.

Die Substanzen sind bei Verwendung von Tinten über Düsen aus einem speziellen Vorratsbehälter aufsprühbar, wobei Linien und Raster mittels der Druckersteuerung erzeugt werden.When using inks, the substances can be sprayed on via nozzles from a special storage container, with lines and screens being generated by means of the printer control.

Bekannt ist, daß bei Tintenstrahlschreibern oder Tinten­tröpfchenaufzeichnung des Originaldruckes die Substanzen dem Tintenvorrat beigemengt sind. Vorzugsweise werden für die Substanzen fluoreszierende Stoffe verwendet.It is known that in ink jet recorders or ink droplet recordings of the original print, the substances are added to the ink supply. Fluorescent substances are preferably used for the substances.

Spezielle Lesegeräte lassen dann den Unterschied zwischen Originalen und Kopien erkennen.Special readers can then tell the difference between originals and copies.
