There are two types of magnetic positioning modules currently used in banknotes: one is a magnetic positioning block made of strip-shaped magnets, which can magnetize the gloss ink to a rolling bright strip effect. The other magnetic positioning module has magnetic rubber block carved into uneven thick film groove and pigment in the magnetic field to form stereo magnetizing effect. The method for fixing magnetism in Chinese patent CN110143076A, Chinese patent CN1812886A and Chinese patent CN107415437B is also a method for fixing magnetism and solidifying by one-time fixing magnetism on one side.
