Application of printed computer generated holograms as security elements

The innovation is in the algorithm for the computerized generation of holograms and preparation for printing in correlation with the parameters of production printing techniques. This enables fast and cheap production of unique computer-generated holograms that are widely used in protective printing. The final product, the security element is not only based on a hologram diffraction grating. Instead, the innovation offers a synergy of three security elements; computer manipulation of objects and composition of holo-blocks in order to achieve a large number of combinations; progressive binarization, which is used to imprint the image on the surface of the hologram and connect the input parameters of the algorithm with the parameters of the printing technique used. All this strengthens security while preserving the ability to print at low cost on standard commercial machines.
