Abstract
A magnetic printing apparatus and a magnetic printing method are disclosed. The magnetic printing apparatus comprises a printing device, a magnetically orientating device and a curing device. The printing device is adapted to form a magnetic-ink layer, wherein the magnetic-ink layer comprises a plurality of magnetic pigment flakes therein. The magnetically orientating device is adapted to magnetically orientate the magnetic pigment flakes. The curing device is adapted to cure the magnetic-ink layer. The magnetically orientating device comprises at least one cylindrical magnet that has an S-pole side surface, an N-pole side surface and an end surface for connecting the aforesaid two side surfaces. When being observed from the end surface, at least one of the aforesaid two side surfaces is a curved surface, and the printing substrate is disposed above or beneath the end surface to form an arc-shaped magnetically orientated pattern in the magnetic-ink layer.
