Screen Printing Optical Varible Ink YYM12 Gold To Green

3D magnetic optically variable ink: The printed color block printed by magnetic optically variable ink presents a pair of color changes. When viewed from the front or side under white light, it presents two different colors with the change of the viewing angle of the human eye.

Under the action of a specific magnetic field, the magnetic powder wrapped by the magnetic light-changing raw material is aligned with the action of the magnetic field to form a specific light-changing effect, such as 3D cat's eye, three-dimensional beam effect, etc.

The effect printed by magnetic optical variable ink has strong optical variable characteristics, large color difference change, and obvious features. It can be recognized without any equipment. Its color angle effect cannot be reproduced by any high-definition scanner, color copier and other equipment. The printing feature cannot be imitated by 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 demanding and difficult anti-counterfeiting of currency and securities, and is also used for packaging anti-counterfeiting .
