Abstract

Procédé de fabrication d’un dispositif de sécurité et dispositif de sécurité associé L’invention concerne essentiellement un procédé de fabrication d’un dispositif de sécurité, comprenant les étapes suivantes : - obtention (S310) d’au moins une première, une deuxième, une troisième et/ou une quatrième images en niveaux de gris à partir d’une image numérique en couleurs : -- ladite première image en niveaux de gris comprenant une pluralité de pixels présentant chacun un niveau de gris représentant une première composante de couleur du pixel correspondant de l’image numérique en couleurs, et -- ladite deuxième image en niveaux de gris comprenant une pluralité de pixels présentant chacun un niveau de gris représentant une deuxième composante de couleur du pixel correspondant de l’image numérique en couleurs, - formation (S320) desdites au moins une première et deuxième images en niveaux de gris sur un support physique dudit dispositif de sécurité. Figure pour l’abrégé : Fig. 3.Method for manufacturing a security device and associated security device The invention essentially relates to a method for manufacturing a security device, comprising the following steps: - obtaining (S310) at least a first, a second, a third and/or a fourth grayscale image from a digital color image: -- said first grayscale image comprising a plurality of pixels each having a grayscale representing a first color component of the corresponding pixel of the digital color image, and -- said second grayscale image comprising a plurality of pixels each having a grayscale representing a second color component of the corresponding pixel of the digital color image, - forming (S320) said at least a first and second grayscale images on a physical medium of said security device. Figure for abstract: Fig. 3.
