Achromatic Master-holograms for embossed holography

Perfect solution for high security holograms – catchy and not counterfeitable. Today it is the only in the world achromatic hologram with colour elements. Holographic image is visible while hologram is illuminated from front and from the back. Image contains animation. With Nickel shim produced from our master-hologram you can emboss holograms on threads for banknotes or other high-level security documents. Image element size is 100×100 micrometers. Single hologram can be till 150×150 mm. Invited presentations about our holograms were given at the following conferences: The Holography, HSP Asia, HSP EMEA.

Description

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.

Illuminating hologram from the front and from the back

Below are not edited photographs of such surface relief hologram on photoresist plate. The plate was illuminated from various directions, the camera was facing the plate from same angle. Hologram size: 5x40mm. Inscription “100 GEO 100 GEO” is achromatic, on background we also added true color “green-red-green-red…” strip in height of 1.3mm.
