What it is?
Holographic foil is a diffraction pattern which displays movement or color shifts when viewed from different angles.
How do you detect it?
Authentication of a holographic foil is performed by looking at the visual pattern and changes under varying viewing angles.
How does it work?
The production of holographic foils relies on the generation of 3D nanostructures on the foil surface. Transfer of the foil onto the product or document is then either performed by sticking or hot stamping.
What do we think about this technology?
Like holograms, holographic foils are also available for counterfeiters at very low cost. Therefore, it is not very secure. Moreover, it requires lamination of your packaging and therefore adds substantial cost. It also makes variable printing more challenging compared to a standard varnish finishing since it is more challenging to define varnish free areas with laminates.
Replacing a holographic foil by a Cryptoglyph® will eliminate all costs associated with the foil and the lamination operations, while providing a much higher level of security and ease of use.
