Abstract

Die Erfindung betrifft ein Verfahren zur Prüfung eines Dokuments. Das Verfahren umfasst:- Empfang (302) eines Dokuments (500, 700) mit einem Dokumentenkörper (506) mit einem Tintenstrahldruck eines Bildes (502, 600) durch eine Prüfeinheit (800). Das Bild enthält erste Regionen (414.1, 414.2) die Tintenstrahltröpfchen einer farbstoffbasierten Tinte (216) enthalten, und zweite Regionen (412.1, 412.2), die eine pigmentbasierten Tinte (214) enthalten. Die ersten Regionen sind frei von der pigmentbasierten Tinte und die zweiten Regionen sind frei von der farbstoffbasierten Tinte. Unter sichtbarem Licht ist die pigmentbasierte Tinte nicht von der farbstoffbasierten Tinte unterscheidbar.- Aufnahme (304) eines Prüfbildes das zumindest den Tintenstrahldruck (502) abbildet;- Durchführung (306) einer Bildanalyse umfassend:• Erfassung (308) der Morphologie der Tintenstrahltröpfchen; und• Rekonstruktion (310) eines digitalen graphischen Musters (404) aus dem Prüfbild anhand der Tröpfchenmorphologie;- Vergleichen (312) des rekonstruierten graphischen Musters mit einem Referenzwert zur Prüfung der Echtheit des Dokuments.The invention relates to a method for checking a document. The method comprises: - receiving (302) a document (500, 700) having a document body (506) with an ink jet printing of an image (502, 600) by a verification unit (800). The image contains first regions (414.1, 414.2) containing inkjet droplets of a dye-based ink (216) and second regions (412.1, 412.2) containing a pigment-based ink (214). The first regions are free of the pigment-based ink and the second regions are free of the dye-based ink. The pigment-based ink is indistinguishable from the dye-based ink under visible light.- Recording (304) a test image that depicts at least the inkjet print (502);- Performing (306) an image analysis comprising:• acquiring (308) the morphology of the inkjet droplets; and• reconstructing (310) a digital graphic pattern (404) from the test image based on the droplet morphology;- comparing (312) the reconstructed graphic pattern with a reference value for checking the authenticity of the document.
