Abstract

A magnetic printing apparatus and a columnar magnet. The magnetic printing apparatus comprises printing devices (10, 12), a magnetic orientation device (20), and a curing device (30); the magnetic orientation device (20) comprises at least one columnar magnet (22); the columnar magnet (22) comprises a first end surface (221) and a second end surface (222) disposed oppositely, and multiple side surfaces that are separately connected to the first end surface (221) and the second end surface (222); the multiple side surfaces comprise a first side surface (223) and a second side surface (224) that are disposed oppositely and are flat surfaces, as well as a third side surface (225) and a fourth side surface (226) that are disposed oppositely and are cambered surfaces; the magnetizing direction of the columnar magnet (22) is from the first side surface (223) to the second side surface (224); a printing substrate is disposed at the outer side of the first end surface (221) or the second end surface (222), so that a specific magnetic orientation pattern (30) separately corresponding to each columnar magnet (22) is formed in a magnetic ink layer. The columnar magnet effectively simplifies a magnetic printing plate structure.

Description

technical field [0001] The invention relates to the technical field of magnetic orientation printing, in particular to a magnetic printing device and a columnar magnet for magnetically aligning magnetic pigment flakes. 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, 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 film produces a unique three-dimensional light-changing pattern...
