Latent Image Anti-Counterfeiting Patterns | Photogravure Imitating Printing

Rotate for different reflection angles, and you will be able to see the latent image of a hidden pattern behind the foreground. This is a common anti-counterfeiting measure which has been applied to ordinary banknotes, which is easy to identify, but has certain degrees of technological thresholds.

In the demo clip you can see H and Logo images alternately keep on changing under reflection and non-reflection conditions to help identifying whether it is a fake or not. This technology requires special printing process which can not be implemented on ordinary printing equipment.
