Nanotech’s KolourOptik® security platform uses advanced nano-optics for the most sophisticated security authentication on the market – it transcends barriers found in conventional holograms. KolourOptik technology is the first nanotechnology to seamlessly integrate into the commercial manufacturing process.

Custom Design

We offer unprecedented design options with respect to motion, 3D depth and high-fidelity colour. KolourOptik enables customers to create compelling stories with unprecedented visual effects.

Nano-scale Mastering

KolourOptik uses patented algorithms coupled with electron beam lithography to make hundreds of billions extremely small holes on a metal master. That master is used to transfer the KolourOptik effect to virtually any material.

Manipulating Light

When light hits the surface of the material modified by KolourOptik, different colours and visual effects are created depending on the viewing angle. In this way we can create high-fidelity colour with simulated depth and motion.

Unique Optical Effects

The result is a memorable and unique optical experience that provides uncompromising security.

Why KolourOptik?

Level 1 Overt Authentication

KolourOptik features are ultra-high resolution and can be viewed from long distances. These images distinctly turn ON and OFF and can be detected by the unaided eye.

Difficult to Counterfeit

The patented origination process and nano-scale technology make KolourOptik images virtually impossible to replicate or reverse engineer.

Demands Attention

The distinct look encourages investigation and is viewable in variable light conditions and at a distance.


KolourOptik can be applied on a wide range of materials ranging from metals, plastics, acrylic, cloth, paper substrates and more.

Environmentally Conscious

KolourOptik images are comprised purely of nano-scale holes in refined metals – no dyes or pigments are involved.

Ultra-high Definition

>500,000 DPI and 50,000 PPI produces both large and small images that are ultra-high definition.

Examples of available effects

Bold, singular colours that pop


Using a blend of structural colours to produce photo-like images

Three-dimensional properties add depth to your security image

KolourOptik can be used for any authentication

Hard to Make = Hard to Counterfeit

We manufacture KolourOptik images using the most advanced optical technology available. As a result, the KolourOptik features are visually unique while providing the ultimate in security.

Years of Research, Specialized Equipment

It has taken Nanotech’s team many years to develop the entire KolourOptik process. This process requires patented algorithms, extremely skilled personnel, sophisticated multimillion-dollar equipment and class 1 clean rooms to effectively fabricate master shims while keeping security a priority.

Cannot be Reverse Engineered

Once built, an origination wafer can be used to produce a subsequent master shim – suitable for high-speed, large-volume production. The requirements for production and the nano-scale of this technology ensures the shim cannot be reverse engineered, thereby providing the ultimate in security.

3 Levels of Security

KolourOptik technology is the first to encompass the “3 Level Conventional Security Pyramid”, Level 1 – Overt, Level 2 – Covert and Level 3 – Forensic; all-in-one product.
