Technologies and Security Features

Security Imaging uses proprietary holographic recording technology to produce optically variable security devices. These are branded as 3Digital holograms and are produced on the latest Lightgate machines. The Lightgate is designed in-house and gives the highest optical resolution of any hologram mastering system in the world. Using this completely digital technology we can incorporate many features into the final product. The following briefly describes some of those features.

3Digital Security Features

Full colour 3D and 2D-3D
Two-dimensional or three-dimensional objects in space - products, logo's etc.

Photographic images
Flat photographic images can be replicated but instead of using pigments, diffracted light produces the colours. These are impossible to photocopy.

Micro features
Very small text, pictures and animations that can only be seen with a microscope.

Multi-phase flip images
Elements can be made to change as the holograms is rotated.

Holographic white
A unique process that produces a combination of all colours to give white.

Guilloche diffraction
Computer generated fine lines, as seen on banknotes, but produced holographically. These are impossible to photocopy or reproduce and are generated with unique algorithms.


 

Hidden images
Not visible with the naked eye these images require a special viewing device to be seen. This may be a special lens or light source.

3D portraits
Fully three-dimensional portraits can be incorporated to the design using our Video Images with Parallax (VIP) system.

Ultra high-resolution pixels
The Lightgate is capable of discreet exposures in the order of one thousandth of a millimetre, giving millions of exposures per square inch.

Sequential numbering
To special order, our products can be numbered in sequence for product tracking and grey import protection.

Colour over-printing
Up to 6 colours can be applied to the surface using conventional inks.

Any conventional holographic technique
Any technique seen on any optical hologram can be reproduced with the 3Digital process.
