<p>A method for reproducing on a support a digital holographic matrix comprises the steps of obtaining said matrix by the application of simulation software to a high resolution image, exposing said support by reproducing the holographic matrix, developing the matrix imprinted on the support, and carrying out a bleaching procedure suitable for rendering transparent the holographic matrix imprinted on the support. The support, for example a photographic film, can be inserted into identity documents, passports, credit cards, access cards and the like, as an anti-counterfeiting or anti-fraud means or a means for certification of identity or of a product.</p> |
