PROCEDE DE FORMATION D'UNE IMAGE LASER COULEUR OBSERVABLE SELON DES COULEURS VARIABLES, ET DOCUMENT SUR LEQUEL UNE TELLE IMAGE LASER COULEUR EST AINSI REALISEE

摘要

The present invention relates to forming color laser images that are observable with variable colors. The gray levels are produced by non-reflective, black volumes in a laserable layer that mask the adjacent subpixels and that cause variable colors to appear depending on the angle of observation of the document. The invention is applicable to official documents.
