At present, due to the panic of high-fidelity counterfeit currency on the market, the media should publicize more ink knowledge to help the public identify counterfeit money and prevent unnecessary losses from being deceived.

The other is using black ink to print black stripes on the front of the counterfeit money, and silver ink on the back to print the hologram; · The denomination of light degradable ink, printed with pearlescent ink, no light change effect; ·Yin and yang complement each other; ·The concave and convex feel of counterfeit currency is made by pressing with a hard metal mold; · The number of invisible denominations is printed with a colorless ink and the denomination "100" can be seen without rotation.
