Abstract

L’invention concerne un matériau de formation d’image, un dispositif de détermination d’authenticité et un procédé de détermination d’authenticité dans lequel une image visuellement cachée dans une image imprimée apparaît par superposition de l’image avec un filtre spécifique ou un film, ou une image imprimée change par réglage de l’angle de la matière imprimée faisant partie intégrante d'un filtre ou d'un film, etc. dans le domaine des matières imprimées de valeur telles que les billets de banque, les passeports, les titres de placement, les cartes d’identité, les cartes de crédit, les laissez-passer, etc. qui sont des matières imprimées sécurisées nécessitant un effet anti-contrefaçon. En particulier, l’invention concerne un matériau de formation d’image qui forme une image en utilisant une seconde image formée dans un pas légèrement différent d’un pas d’une première image par utilisation d'un matériau transparent ou d'un matériau d’une couleur différente d’une couleur d’un matériau formant la première image à un moment de réflexion régulière, sur la première image formée par rassemblement des éléments d’impression de forme convexe dans un pas prédéterminé et des pixels de forme convexe en utilisant un matériau ayant des caractéristiques de variation de couleur tel qu’un pigment perlé ou un matériau à cristaux liquides, etc. En outre, les éléments d’impression sont configurés pour commander un changement de mouvement d’une image de moiré et un changement de forme en changeant légèrement chaque pixel de l’image formant le moirage, et supprimer la distorsion se produisant dans l’image de moiré à un minimum et commander la perception de profondeur du moirage et la vitesse de changement en ajustant le pas entre les images.
