As the further development of the optically variable ink, other two-line anti-counterfeiting elements are introduced, for example, magnetic elements are added into the structure of the existing optically variable pigment, so that the optically variable pigment flake has the angular color changing function and the magnetic characteristic at the same time, the anti-counterfeiting technology of the optically variable ink is upgraded, and the magnetic optically variable ink (OVMI) is formed. The magnetic optically variable ink integrates the characteristics of the magnetic ink and the optically variable ink into a whole, so that optically variable colors have a flowing effect, the light and shade change is more obvious, and the anti-counterfeiting requirement can be met. The web screen printing machine according to the embodiment can be used for printing magnetic optically variable ink.

Further, a scraper 401 is also arranged on the screen roller 400 in a matching manner, and the scraper 401 can remove foreign matters on the network. The embossing roller 500 is in direct gear engagement transmission with the fixed magnetic roller 200 through two bridging teeth 6. The two gap bridge teeth 6 are synchronized by a keyed gap bridge shaft 7.
The device capable of realizing the screen printing of the colorful light column on the winding drum is installed on the machine side as shown in figures 1-26, and the fixed magnetic roller 200 comprises a fixed magnetic block 1, a fixed magnetic shaft 2, a magnetizing roller 3 and a fixed magnetic roller sleeve 4 which are coaxially arranged from inside to outside in sequence; the outer wall of the magnetizing roller 3 close to the fixed magnetic roller sleeve 4 is provided with at least one groove for placing the fixed magnetic block 1; the fixed magnetic shaft 2 is connected with two roller gear seats 5 in a key way, and the two roller gear seats 5 are arranged at two ends of the fixed magnetic roller sleeve 4 from left to right and are connected with the fixed magnetic roller sleeve 4 into a whole; the fixed magnetic shaft 2 is arranged on the machine side through a fixed magnetic bearing 8; the roller gear seat 5, the fixed magnetic shaft 2, the magnetizing roller 3 and the fixed magnetic roller sleeve 4 can synchronously rotate.
