Abstract

La présente invention concerne un support de données pour la prévention de contrefaçon présentant une structure complexe qui ne peut être analysée ou imitée aisément et dans laquelle des couleurs peuvent être combinées de diverses manières et des éléments d'information peuvent être visuellement vérifiés au niveau de l'angle d'observation d'une zone de réflexion uniforme et un zone de lumière diffuse. Le support de données présente une zone d'images permettant de signaler une information et une zone d'images d'arrière-plan, chacune des zones étant constituée d'un motif de pixels ayant une densité de pixels réglée pour chaque matériau de brillance et chaque couleur de matériau colorant. Le motif de pixels est préalablement réglé, par la mise en correspondance de couleurs, de sorte que les couleurs de la zone d'images d'informations et la zone d'images d'arrière-plan deviennent isochromatiques pour la source lumineuse d'éclairage au niveau de l'angle d'observation d'une zone quelconque de lumière diffuse ou d'une zone de lumière de réflexion uniforme et deviennent non isochromatiques au niveau d'autres angles d'observation.
