2. Special anti-counterfeiting technology of banknotes

1) magnetic micro text safety line the safety line in banknotes is transparent against light, visible text, and the instrument detects magnetism

2) light variable ink denomination number the text printed with this ink is one color when viewed vertically with the face, and another color when tilted at a certain angle

3) invisibility is not easy to choose for the experiment of plastic materials. The denomination number is a trace used in carving.
