Problems solved by technology

For example, in a prior art, a Fresnel reflector is used to produce a spherical magnetic field to form a cone-shaped or hemispherical magnetic field distribution, thereby producing a cone-shaped or hemispherical stereoscopic pattern, but the stereoscopic effect is relatively poor

Embodiment Construction

[0026] See figure 1 , figure 1 is a schematic diagram of a manufacturing apparatus for a magnetic pigment print according to a first embodiment of the present invention. The manufacturing device of the magnetic pigment printed matter in this embodiment is a drum-type continuous printing device. Wherein, the printed matter substrate 11 is driven in a predetermined direction under the action of the tension wheels 14 and 18 rotating around their respective rotation axes, the roller 17 or other transmission devices. The printed matter substrate 11 may be paper, film or other flexible material. Inking rollers 15 , 16 print magnetic ink (not shown) on the surface of print substrate 11 . The magnetic ink contains magnetic pigment flakes (not shown) that can be oriented along the direction of the magnetic field, such as magnetic optically variable pigment flakes.

[0027] The printed matter substrate 11 with magnetic ink printed on its surface is transferred onto a cylinder 17 . ...

Abstract

The invention provides a magnetic orientation device, a manufacture device and a manufacture method of a magnetic pigment printed product. The magnetic orientation device comprises a drive device and a magnet, wherein the drive device is used for driving the magnet to rotate around a rotation shaft; and the rotating magnet produces a magnetic field to realize magnetic orientation of magnetic pigment flakes in magnetic ink printed on the substrate surface of the printed product, thereby forming a magnetically oriented pattern with three-dimensional effect in the magnetic ink. According to the invention, the magnetic orientation device, the manufacture device and the manufacture method of the magnetic pigment printed product provided by the invention can improve the three-dimensional effect of the magnetically orientated pattern by using the magnetic field produced by the rotating magnet to realize magnetic orientation of the magnetic pigment flakes in the magnetic ink.

Description

technical field [0001] The invention relates to the field of magnetic alignment printing, in particular to a magnetic alignment device, manufacturing device and manufacturing method of magnetic pigment printed matter. Background technique [0002] At present, magnetic ink is widely used in various anti-counterfeiting fields, and the magnetic ink usually contains magnetic pigment flakes that can be oriented along the direction of a magnetic field, such as magnetic optically variable pigment flakes. Therefore, it is necessary to form an artificially designed specific magnetic field inside the magnetic ink during the printing process, so that the magnetic pigment flakes can be oriented at different angles in different regions, so that the magnetic pigment flakes can produce a unique magnetic orientation pattern in the magnetic ink. . [0003] At present, in the printing process of the magnetic ink in the prior art, a specific magnetic field generated by a stationary magnet is ...
