Holograms can be made using both Traditional (Analog)
Holographic Technique and Digital Holographic Manufacturing
Technique. Holostik offers both Traditional and Digital Holograms,
details of which are given below:
2D/3D: These are by far the most common type of holograms. These holograms (and therefore the artwork of these holograms) may be of two layers
(i.e. with a background and a foreground) or of three-layers (with a background, a middle ground and a foreground). The matter of the middle ground and the foreground in the case of three-layer holograms and the matter of the foreground in the case of the two-layer holograms are usually superimposed over the matter of the background of the hologram. These holograms display a unique multilevel ,
multi-colour effect. These images have one or two levels of flat graphics “floating” above or at the surface of the hologram. The matter in the background appears to be “under” or “behind” the hologram, giving the illusion of depth.
Apart from being the most cost-effective type of holograms, the 2D/3D Holograms, when viewed under a variety of sources of light, are extremely eye-catching.

Dot Matrix Technology: The hologram produced
using Dot Matrix technology are considered to be one of the most secured
hologram internationally. These holograms are originated using
highly sophisticated and very expensive Dot Matrix System. This
kind of technology allows creating or originals of holograms with
a resolution of up to 10 microns. Dot Matrix technology makes it
possible to create originals of computer synthesized holograms
with high level of protection. The hologram includes elements that
cannot be manufactured using other optical or printing
technologies. this technique requires development of various
algorithms for designing optical elements that shapes scattered
radiation patterns.
E-Beam Technology: The hologram produced using
electronic beam technology are considered to be the most secured
hologram internationally. These holograms are originated using
highly sophisticated and very expensive E-Bean Lithography system.
This king of technology allows creating of originals of holograms
with a resolution of up to 0.1 micron. Electron Bean technology
makes it possible to crate originals of computer synthesized
holograms with high level of protection. The hologram includes
elements that cannot be manufactured using other optical or
printing technologies. The technique requires development of
various algorithms for designing optical elements that shapes
scattered radiation patterns. This origination technique offers
manifold possibilities for combining various security features.
The technology of computer synthesis of holograms opens ample
opportunities for the creation of OVD with highest level of
security
