When looking directly or sideways under white light, as the viewing angle of the human eye changes, it presents two different colors. The light change characteristics are strong, the chromatic aberration changes greatly, and the characteristics are obvious. It can be recognized without any equipment and the color angle effect is impossible. Reproduced with any high-definition scanner, color copier and other equipment, the printing features cannot be imitated with any other ink and printing method, and the anti-counterfeiting reliability is extremely strong, so it is designated by many countries in the world for the most stringent and difficult requirements.
