Hologram
Holograms are among the most recognizable and reliable security techniques for documents and products. Their unique, three-dimensional appearance and complex production technique make them particularly difficult to counterfeit and at the same time easy to verify with the naked eye.
How it works
- Created by using laser light and diffraction patterns, which together form a three-dimensional image.
- This image changes depending on the viewing angle and light incidence.
- The effect cannot be replicated with a standard printer or copier.
Security
- They are highly complex and costly to replicate.
- Their three-dimensional appearance and unique light reflections are immediately recognizable.
- Can be combined with serial numbering, microtext or QR codes.
