СПОСОБ ПОЛУЧЕНИЯ ЗАЩИТНОЙ ГОЛОГРАММЫ

摘要

Data carriers are marked by means of protective holograms utilizing a hologram property to modify the spatial position and color of a restored image when the orientation of the hologram is modified in relation to a light source. Inventive method consists in producing a required image, recording a hologram from it, producing a metallic matrix based on the hologram and successively replicating the protective hologram along the surface of a polymeric film by embossing the matrix on it. Prior to producing the matrix for replicating holographic images of the required image which consists of a range of holographic images, an operation for producing a common metallic matrix from each individual holographic image is carried out, thereby reconstructing the mirror image of the required image.
