Abstract

Fabrication d’une image à partir d’une structure holographique L’invention vise un procédé comprenant : fourniture d’une couche (6) holographique métallique comprenant une sous-couche (10) de métal et formant un arrangement (26) de pixels (27), chaque pixel comportant une pluralité de sous-pixels (28) de couleurs distinctes ; destruction partielle, par un premier rayonnement laser (LS1), de la couche holographique de sorte à retirer sélectivement des portions de la sous-couche de métal pour former des zones démétallisées (30) ; et lamination de la couche holographique avec des couche supérieure (4) et inférieure (12) en polymère ; et une personnalisation de l’arrangement (26) de pixels par formation au moyen d’un deuxième rayonnement laser (LS2), dans la couche holographique, de perforations (40) révélant localement des zones (44) de nuance de couleur dans les sous-pixels (28) causées par des régions sous-jacentes (42) de la couche inférieure situées en regard desdites perforations, de sorte à former une image personnalisée (IG). Figure pour l’abrégé : Fig. 3D
