Abstract

Official abstract text for this publication.

The present invention is directed to a method for supplying an optical security element in a value document, as well as to an accordingly devised apparatus for adjusting an optical security element as well as to the value document per se. According to the invention a method is proposed which makes it possible to supply a known optical security element in an especially simple technical way, without a vapor deposition of embossed structures being necessary in this connection. Further the present invention is directed to a computer program product having control commands, which executes the method or operates the proposed apparatus.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for supplying an optical security element in a value document, having: supplying a foil stack having two consecutive transparent foils, laminating the foil stack for supplying a card body, wherein a silver ink and at least one structure layer are incorporated at the two transparent foils such that in interaction with the two transparent foils, the optical security element has a three-dimensional optical impression upon viewing, and wherein the silver ink is incorporated into the at least one structure layer. 2. The method according to claim 1 , wherein the structure layer is supplied by means of a relief lacquer and/or an embossed layer. 3. The method according to claim 1 , wherein an effect ink is incorporated between the transparent foils. 4. The method according to claim 1 , wherein the structure layer is configured to be transparent or semi-transparent. 5. The method according to claim 1 , wherein the structure layer is configured as glazing in color. 6. The method according to claim 1 , wherein the structure layer is provided as an embossed foil. 7. The method according to claim 1 , wherein the structure layer is supplied using relief printing. 8. The method according to claim 1 , wherein the silver ink is incorporated into the card stack above or below the structure layer. 9. The method according to claim 1 , wherein the optical security element is generated by means of the silver ink and/or by means of the structure layer. 10. The method according to claim 1 , wherein an outer transparent foil is configured with respect to the card body as a protective layer. 11. The method according to claim 1 , wherein the silver ink is incorporated by means of screen printing technology. 12. A value document formed from a laminated foil stack forming a card body having an optical security element, having two consecutive transparent foils, wherein a silver ink and at least one structure layer are incorporated at the two transparent foils such that in interaction with the two transparent foils, the optical security element has a three-dimensional optical impression upon viewing, and wherein the silver ink is incorporated into the at least one structure layer. 13. An apparatus for supplying an optical security element in a value document, having: a supplying unit devised for supplying a foil stack having two consecutive transparent foils, a lamination unit devised for laminating the foil stack for supplying a card body, wherein a silver ink and at least one structure layer are incorporated at the two transparent foils such that in interaction with the two transparent foils, the optical security element has a three-dimensional optical impression upon viewing, and wherein the silver ink is incorporated into the at least one structure layer. 14. A computer program product having control commands which implement the method according to claim 1 .
