Abstract:
There is provided an apparatus for forming a magnetic pigment pattern on an article. The apparatus includes: a magnetic pattern mold having nonmagnetic pattern grooves engraved in a predetermined pattern and providing predetermined magnetic field lines on a pattern-forming object surface of an article by generating magnetism in areas outside the nonmagnetic pattern grooves; and a spray unit spraying an adhesive resin composite containing a ferromagnetic pigment onto the pattern-forming object surface of the article. A predetermined magnetic pigment pattern is formed while the magnetic pigment of the adhesive resin composite that is applied to the pattern-forming object surface of the article is rearranged along magnetic field lines generated by the magnetic pattern mold.
