The work aims to explore the research strategy to upgrade the anti-counterfeiting technology in China by researching the related performance of optically variable magnetic ink and its application in anti-counterfeiting. With magnetic ink, optically variable ink and optically variable magnetic ink as the research objects, the anti-counterfeiting features of optically variable magnetic ink, the principle of optically variation, the printing machine modification, the manufacturing method of optically variable magnetic film fragment and the advantages of optically variable magnetic ink were systematically elaborated, and the application prospect of optically variable magnetic ink was forecasted. Optically variable magnetic ink integrates magnetic ink and optically variable ink features as a whole, the optically variable color has more flowing effects and the light-shade changing is more obvious, which can meet the higher security requirements.
