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.

Abstract: A three-dimensional out sole having a pattern having improved quality and durability has a dye permeated into the surface of the outsole. A depth to which the dye penetrating the micropores is 0.08 mm to 0.12 mm. The dye is permeated into the microspores through vacuum suction. The dye is digitally printed on a thermoplastic sheet. The thermoplastic sheet on which the dye is printed is heated to be softened with flexibility. The softened sheet having flexibility is closely attached to a surface of the shoe outsole having the three-dimensional shape through vacuum adsorption and then is permeated therein.
