New diffractive effects for security holograms produced with Geolas Originators

摘要

New embossed hologram originating technique, producing effects which are not possible to reproduce with commonly used image-matrix Kinemax type equipment was developed. Thus, Geola Digital Ltd. is launching a series of unique equipment devoted to embossed holograms originating. Equipment allows one to produce master-holograms containing simultaneously achromatic and true colour deep 3D images. Such images are perfectly viewable while illuminated with light sources situated in front of the hologram or at its back. The Originators also can produce and with higher precision all effects achievable with commonly used image-matrix originators. Therefore, an ultimate goal to have one Originator assuring all security features from Level 1 to Level 4 is achieved. Moreover, pulsed laser employed in Geola's originators enable one to produce whole holograms windows quickly, employing an optical holograms recombination instead of mechanical one.
