Achromatic master-originals for embossed holography

We are producing unique surface relief master-original holograms. The holograms are digitally printed on photoresist plates?with our Originators.

Our achromatic holograms can simultaneously have deep holographic 3D images and?true color elements.

Another unique feature of those achromatic holograms is their ability to replay holographic image equally well when they are illuminated from the front and from the back. This feature opens possibilities to use them as banknotes security feature. Also with this technique is possible to mass-produce holographic advertising posters which can be placed at building windows and illuminated from inside the building.
