Embodiment Construction

[0026] See figure 2 , figure 2 is a structural schematic diagram of the magnetic printing device of the first embodiment of the present invention. In this embodiment, the magnetic printing equipment is a roll-type continuous printing equipment, including printing devices 110 , 111 , a magnetic orientation device 123 , a curing device 130 and a conveying device 120 .

[0027] In this embodiment, the transfer device 120 transfers the printed matter substrate 100 through the printing devices 110 , 111 , the magnetic orientation device 123 and the curing device 130 . The printing devices 110 and 111 are respectively arranged in a cylindrical shape, and then can apply magnetic ink on the printed matter substrate 100 to be printed in a roll printing manner to form a magnetic ink layer (not shown). The printed matter substrate 100 can be flexible materials such as paper, cardboard, film and plastic that need to be magnetically printed. The magnetic ink layer contains magnetic pi...

Abstract

The invention provides magnetic printing equipment and a magnetic printing method. The magnetic printing equipment comprises a printing device, a magnetic orientating device and a curing device, wherein the printing device is used for coating magnetic printing ink onto a substrate of a printed matter to form a magnetic printing ink layer comprising a plurality of magnetic paint sheets, the magnetic orientating device is used for magnetically orientating the magnetic paint sheets, and the curing device is used for curing the magnetic printing ink layer. Besides, the magnetic orientating device comprises at least one columnar magnet. Each columnar magnet comprises an S-pole side, an N-pole side and an end face for connecting the S-pole side with the N-pole side, at least one of the two sides is a curve surface when viewed from the end face, and the substrate of the printed matter is disposed above or below the end face of the columnar magnet so that arc magnetic orientated patterns can be formed in the magnetic printing ink layer. By the magnetic printing method, the special arc magnetic orientated patterns can be formed in the magnetic printing ink layer by the aid of the magnets, so that the printed matter has variable pattern effects.

Description

technical field [0001] The invention relates to the field of magnetic orientation printing, in particular to a magnetic printing device and a magnetic printing method. Background technique [0002] At present, magnetic optically variable pigment flakes are widely used in various anti-counterfeiting fields. In addition to the optically variable effect of traditional optically variable pigments, the magnetic optically variable pigment flakes can also be oriented along a magnetic field. Therefore, it is necessary to form an artificially designed specific magnetic field inside the magnetic ink layer containing the magnetic optically variable pigment flakes during the printing and curing process, so that the magnetic optically variable pigment flakes can have different angular orientations in different regions, thereby making the magnetic optically variable pigments The flakes produce a unique light-changing pattern effect in the print. [0003] However, in the prior art, the S...
