1. An apparatus for forming a predetermined magnetic pigment pattern on an article, the apparatus comprising:
a magnetic pattern mold having nonmagnetic pattern grooves engraved in a pattern opposite to the predetermined magnetic pigment pattern, and configured to generate magnetism in areas outside the nonmagnetic pattern grooves such that predetermined magnetic field lines are provided on a pattern-forming object surface of the article outside the nonmagnetic pattern grooves; and
a sprayer configured to spray an adhesive resin composite containing a ferromagnetic pigment onto the pattern-forming object surface of the article such that the predetermined magnetic pigment pattern is formed by the ferromagnetic pigment of the adhesive resin composite that is applied to the pattern-forming object surface of the article and rearranged along the predetermined magnetic field lines generated by the magnetic pattern mold.
