摘要 |
The invention relates to a currency or security document having an anti-counterfeit device. According to the invention, the anti-counterfeit device takes the form of a discontinuous reflecting surface (100) consisting of a succession of individual reflecting elements (101) applied to one face (10) of the document (D) by transfer and organised in one general direction (DG); each individual reflecting element (101) has both a dimension of a plurality of millimetres and optimum compactness for a given area of reflection, in such a way that the reflection phenomenon appears clearly to the naked eye and blinds the known systems of optical reproduction or analysis. The invention also relates to a supporting strip having a transferable reflecting design making it possible to produce such a document. The invention is used particularly for the production of bank notes provided with an anti-counterfeit device applied by transfer. <IMAGE> |
