Abstract:
A method of making a data carrier medium comprising a first carrier layer and a graphical inscription on said first carrier layer and constituted, for example, by a text, by a photograph, or by digital data. The method comprises the steps consisting in performing the graphical inscription by depositing at least one metal lithographic deposition of metal on the first carrier layer, in supplying the first carrier layer made of a transparent material, and further in placing a second carrier layer made of a transparent material in superposition on the first carrier layer so as to protect the graphical inscription.
