A transparent resin is injection molded to create a marker (10) as an integrally molded article (lenticular lens portion (11)) including convex surfaces (112) and recesses (113) formed on the rear side of the convex surfaces. The recesses (113) are filled with coating films (115) formed by applying and curing a fluid coating material. Each recess (113) is arranged corresponding to a convex surface (112) so that the coating films (115) can be observed as optically distinguishable from the side of the convex surfaces (112).

The method for generating a final image for the printing thereof on a lenticular support includes an acquisition of a first file including a plurality of images; an automatic extraction of a determined number of images of the first file as a function of a maximum number of images to extract, the images being ordered according to a first order; a redimensioning of the images as a function of a parameter of density of lenses per unit surface area of a predefined printable support, called the pitch; an interlacing of the extracted images; and a generation of a final image to be printed on a lenticular support.
