Making copies is a simple and faster method for counterfeiting. Most of the anti-counterfeiting effects from Holo solution are unable to be copied intact. However, it is not easy for the general users to distinguish the copied ones from the original piece. Some important documents do not need to be entirely prohibited from making copies; instead, it is necessary to easily identify the original from the copied pieces, such as inspection reports, contracts, certificates, testimonial, and guarantees certificates, etc. Only if it is easy to identify the original from the duplicate can both parties’ interests be well protected, and the original copy’s authority and sense of value can be well validated.

Anti-copying is a kind of security background line. Some regular textures can be seen before making copies without feeling much difference, but some specific patterns would appear on the copied pieces, which make identification much easier.
