Diffractive Security Elements by KURZ

With our patented and not commercially available TRUSTSEAL® Protect technology, you protect emblems long term against tampering and counterfeiting – even if only the mesmerizing design is recognizable at first glance.

Nanotext & Microtext

Our nanotext/microtext can only be checked with a magnifying glass or a microscope.

Diffractive Black

Tilting the hologram along the horizontal axis makes the security elements on 'diffractive black' visible.


A combination of different registered colors to make the tax stamp more secure.

TRUSTSEAL® Protect security elements boast various integrated features that protect and reliably authenticate your products in the long term. Any attempt to detach it, for example, is already clearly evident. The holographic features increase security in visual authentication.

Partial Metallization

Partial metallization can isolate security elements such as microtexts or small images.


If successfully authenticated with a special Taggant Reader, a light indicator appears.


The hidden spotlight effect is made visible with the help of a point light source.
