What are the 3 designs for counterfeit-proof features?
Counterfeit-proof features can be designed in 3 different ways:
- Open, i.e. can be recognised and therefore verified by anyone
Example: holograms, use of colour-shifting inks
- Hidden, i.e. only verifiable by experts with applicable knowledge
Example: microscripts, guilloches
- Forensic, i.e. can be used as evidence in court
Example: special individual markers
