Types of Hologram Masters
Hologram classified into different types with reference to the degree of level of optical security incorporated in them during the process of master origination;
2D/3D LAYERGRAM MASTER
These are by far the most common type of holograms preferred by customers. These holograms may be of two layers i.e. with a background and a foreground or three layers - with a background, a middle ground and a foreground.
The matter of the middle ground 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-color 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 hologram the 2D / 3D Hologram, when viewed under a variety of sources of light, are extremely eye – catching
DOT MATRIX – PIXELGRAM MASTER
The hologram produced using Dot Matrix technology are considered to be the high secured hologram internationally. These holograms are originated using highly sophisticated and very expensive Dot Matrix System. This technology allows creating of 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 of printing technologies. This technique requires development of various algorithms for designing optical elements that shapes scattered radiation patterns.
The main characteristics of Dot-Matrix Pixel gram various kinds of features possible in this type of origination are mentioned below:
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.
ELECTRON BEAM – LINEARGRAM MASTER
The electron beam masters are originated using highly sophisticated and very expensive e-beam lithography system and this is the latest technology in the world at present. This kind of technology allows creating of originals of holograms with a resolution of up to 0.1 microns.
E-beam technology makes it possible to create originals of computer synthesized holograms with high level of protection. The holograms include 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.
This type of hologram offers features like the viewing of four lasers at a single point, 2D/3D raster text, Mini Switch Effect, Four Channel, Pure 3D effects. Some of the other various kinds of features possible in this type of origination are mentioned below:
