| Zusammenfassung: | This invention relates to a method for producing a data carrier having at least in partial areas a transparent plastic layer which is provided at least in a partial area with a surface relief in the form of a lens structure. Further the invention relates to a data carrier produced by this method and to an apparatus for carrying out the method.
The invention relates to different methods for distortion-free production of data carriers having at least in partial areas a transparent plastic layer with a surface structure in the form of a lens structure. The surface structure can be produced by cutting method or embossed by applying heat and pressure. Alternatively the surface structure can be produced as a separate element which is connected after its production with the data carrier. |
