Title (EN) METHOD OF FORMING A SECURITY DOCUMENT
(FR) PROCÉDÉ DE FORMATION D'UN DOCUMENT DE SÉCURITÉ
Abstract:
(EN) A method of forming a security document is provided. The method comprises: providing a security document substrate, the security document substrate comprising a security device comprising a colour shifting element and a light control layer covering at least a part of the colour shifting element, wherein the light control layer has a surface structure comprising one or more elevations and depressions that modifies the angle of light from the colour shifting element to generate a first optical effect, and; selectively modifying a part of the light control layer so as to generate a second optical effect different from the first optical effect.
(FR) L'invention concerne un procédé de formation d'un document de sécurité. Le procédé comporte les étapes consistant à: mettre en place un substrat de document de sécurité, le substrat de document de sécurité comportant un dispositif de sécurité comportant un élément à décalage de couleur et une couche de contrôle de lumière recouvrant au moins une partie de l'élément à décalage de couleur, la couche de contrôle de lumière présentant une structure de surface comportant une ou plusieurs élévations et cuvettes, qui modifie l'angle d'une lumière provenant de l'élément à décalage de couleur pour générer un premier effet optique, et; modifier sélectivement une partie de la couche de contrôle de lumière de façon à générer un deuxième effet optique différent du premier effet optique.
