Abstract

Procédé de fabrication d’un dispositif de sécurité à variabilité optique et dispositif de sécurité associé L’invention concerne essentiellement un procédé de fabrication d’un dispositif de sécurité (100), comprenant les étapes suivantes : - formation d’une grille (112) comprenant un entrelacement d’au moins une section d’un premier type (122) et d’une section d’un deuxième type (124), - formation d’une pluralité de micro-perforations (130) dans une couche métallique (114), un séparateur optique (116) transparent étant positionné entre la grille (112) et la couche métallique (114), au moins une micro-perforation (130) étant positionnée de sorte que : - lorsque le dispositif de sécurité est orienté selon une première orientation (O1), ladite au moins une micro-perforation (130) et la section du premier type (122) sont superposées de sorte à créer une première image, et - lorsque le dispositif de sécurité est orienté selon une deuxième orientation (O2), ladite au moins une micro-perforation (130) et la section du deuxième type (124) sont superposées de sorte à créer une deuxième image. Figure pour l’abrégé : Fig. 1.
