Title (DE) ANTI-KOPIERFILM FÜR DOKUMENTE GEGEN KOPIEREN DERSELBEN IN EINER KOPIEREINRICHTUNG MIT DEFINIERTEM ÖFFNUNGSWINKEL
(EN) ANTI-COPYING FILM FOR DOCUMENTS TO PREVENT COPYING OF THE SAME IN A COPYING DEVICE HAVING A DEFINED OPENING ANGLE
(FR) FILM ANTI-COPIAGE POUR DOCUMENTS DESTINE A EMPECHER LEUR COPIAGE DANS UN DISPOSITIF DE COPIAGE A ANGLE D'OUVERTURE DEFINI
Abstract:
(DE) Ein Anti-Kopierfilm besteht aus Zylinder-Kalotten-Linsen und zugeordneten Abdeck-Balken mit definierter Ausbildung und Dimensionierung. Zusätzliche Deckschichten und Pigmente in den Balkenmaterialien ergeben optimale Abdeck- und Durchsicht-Effekte. Eine optimale Farbtonwahl erhöht die Anti-Kopierwirkung und die Versendbarkeit der Filme.
(EN) The anti-copying film consists of cylindrical concave lenses and covering bars allocated thereto having a defined configuration and defined dimensions. Additional covering layers and pigments in the bar materials provide optimum covering and undertone effects. By selecting color tone in an optimum manner, the anti-copying effect and the usability of said films are improved.
(FR) L'invention concerne un film anti-copiage comportant des lentilles concaves cylindriques et des barres de recouvrement associées présentant une configuration et un dimensionnement définis. Des couches de recouvrement supplémentaires et des pigments situés dans les matériaux constitutifs des barres assurent des effets optimaux d'opacité et de transparence. Un choix optimal de la chrominance permet d'améliorer l'effet anti-copiage et les possibilités d'emploi de ces films.
