First generation holograms were made with this technique. A 2D/3D hologram has two or more levels, has a good feel of depth and looks nice and colourful. Perhaps such holograms are these days preferred more for promotional applications. Such holograms may have a flip effect to enhance the aesthetics.
Security ratings are generally considered low for this technique
Dot Matrix Origination
Dot Matrix are the more vibrant holograms. They invariably incorporate kinetic effects that make it interesting to the viewer, and therefore easier to register as an anticounterfeit device.
Security ratings are medium, may be considered good enough for most commercial security applications.
This is the latest development in the hologram origination techniques, and allows very high resolution for nano features and very sharp imagery. Colour control and animated hidden images are only some of the new features that this technique has introduced.
Security ratings for this are medium to high, depending on the complexity of the features proposed.
Overt features are those that are clearly visible in the hologram and are meant to be verified by the consumer/end user. They are as follows:
2D/3D Background layers
Concealed Image visible only at specific angles
Covert features are features that are invisible to the naked eye, but can be verified with the help of some simple hand held instruments like a Laser Pointer, Magnifying Glass or Decoding Films. These are essentially meant for verification by the hologram users’ internal team.
Animated Covert Laser Readable Message (CLR)
Forensic features are those features that may only be decoded by using some advanced and complex instruments like high-powered Microscope. Such features are particularly helpful to establish conclusively the authenticity of the hologram in question. This can be particularly helpful in fighting product warranty cases.
