Nanocrypt®
High-security Holograms (OVDs)

The next generation of OVDs (optically variable device) – Nanocrypt® technology offers unique optical features and high-level security features in the nano spectrum.

The Nanocrypt® is one of the most secure and technologically advanced nano-optical imaging systems. With resolutions up to 640,000 dpi and tolerances within 2 nm (nanometers), nano-structures and anti-counterfeiting security features can be achieved which cannot be reproduced and can therefore legitimately be termed 100% counterfeit-proof.

Application areas for Nanocrypt®

Nanocrypt protected security hologram

Cutting edge counterfeit protection at banknote level for the high-security sector

Nanocrypt® is a fourth generation OVD (optically variable device). The sophisticated security features that can be achieved with Nanocrypt® technology cannot be simulated or reproduced using conventional techniques (analog or digital production technologies such as dot-matrix imaging). Forensic and machine-readable elements and structures are possible in addition to the visible security features.

Holograms with Nanocrypt® technology are primarily used in high-security applications such as documents, identity cards, bank notes and bonds.

Nanocrypt® – the details

The Nanocrypt® technique of producing holograms (OVDs) is based on electron-beam lithography. Computer-aided control and a resolution of up to 640,000 dpi allow unique nano-structures and optical 3D microstructures such as optical lenses or nano-text to be produced in sizes of 300 nm (nanometers).

Nanocrypt® technology allows forensic security features to be achieved in the nano range which can be authenticated with the aid of digital or laser microscopes.

Nanocrypt OVD Security Features

Advanced and unique Security Features

Highly sophisticated security features and nanostructures with up to 640,000 dpi resolution can be realized with Nanocrypt® origination technology. These features cannot be simulated or represented by conventional techniques (analog as well as digital origination techniques such as dot-matrix). Nanocrypt® offers unique features and possibilities.

Nanocrypt OVD Security Features

Countless possible combinations

Counterfeit-proof optical features that are visually striking and at the same time offer maximum security enable countless functional and visually appealing design options. In addition, by combining security features of different levels, counterfeit protection can be significantly increased. While some features are purely security elements, others can be used as visual effects. The challenge lies in combining and customizing the individual features to create optimal counterfeit protection and a visually appealing design.

Nanocrypt® Features

Nanocrypt OVD Security Features

Relief Effect

Razor sharp relief effect which is achieved through regress calculation of 3D microstructure. This relief effect creates a striking visual effect with clear and brilliant contours due to the detailed and fine modulation.

Nanocrypt OVD Security Features

Metallic Effect

This metallic reflective effect does not have any holographic color and is visible at different viewing angles. Besides smooth surfaces, structured surfaces can also be realized, which have the appearance of brushed steel.

Nanocrypt OVD Security Features

Pure White Effect

This pure white effect (or achromatic white) does not have any holographic color. The surface looks even and smooth thanks to the high resolution.

Nanocrypt OVD Security Features

Kinetic Effects

Kinetic movements which simulate a rotation effect as well as a zoom effect. Compared to conventional methods, the colors appear more brilliant, richer and purer and exhibit higher diffraction, as the microstructures produce high diffraction efficiency.

Nanocrypt OVD Security Features

Guilloches

A set of thin lines of complex geometry (guilloche pattern) drawn in high resolution. The technology allows continuous visual changes of color along each seperate line. The patterns in the example above are visually designed so that the guilloches are set in motion when the hologram is tilted.

Nanocrypt OVD Security Features

Expand Effect and Mirror Lens

Enhanced shrinking/expanding feature. The object (in this example the honeycomb pattern) will shrink or expand at the same position when the hologram is tilted from left to right, top to bottom or vice versa. The mirror lens shows a lens effect, available in different designs such as shaped lens or lens with incorporated/hidden text and images.

Nanocrypt OVD Security Features

Gradient Effect

A diffraction effect with a brilliant color gradient, which covers a certain color spectrum and thus creates a strong holographic effect (“rainbow effect”). Double as well as asymmetrical color gradients are also possible, with the help of which unique optical effects can be achieved.

Nanocrypt OVD Security Features

Dynamic Effect

Motion effects that consist of lines, dots and other micro geometric forms or text. The dynamic movements are well visible also under poor lightning conditions.

Nanocrypt® High Security and Forensic Features

Nanocrypt OVD Security Features

Microtext and Nanotext

Nanotext can only be authenticated with a magnifying glass or a microscope while the microtext in this example is 100 micron (0.1 mm) in size and barely legible to the naked eye. Microtext and nanotext can be integrated as security features in various locations and in different designs within the same hologram.

Nanocrypt OVD Security Features

Microtext 350 µ

The microtext “ORIGINAL” has a font height of 350 micron (0.35 mm) and thanks to the high-resolution Nanocrypt® origination technology is well readable even by the naked eye.

CLR Covert Laser Readable

Multi-Level CLR Elements and Animated CLR

CLR (Covert Laser Readable) information is not visible to the naked eye and is integrated into the hologram during the origination process. Covert information become visible and can be decoded by examining the coded areas with a special CLR decoder under specific wavelengths. Both static and animated elements are possible. Due to the extremely high resolution, even the smallest areas on the hologram can be encoded with pin sharp CLR elements.

Other High-Security Features

Nanocrypt® allows forensic security features to be achieved in the nano range which can be authenticated with the aid of digital or laser microscopes. From microscopic nano-images to modulated nanostructures, the possibilities are almost limitless. Specific and customized security concepts can thus be realized that are absolutely counterfeit-proof.
