Method of forming a color laser image observable with variable colors, and a document on which such a color laser image is made in this way
Abstract:
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.
