Abstract
A manufacturing method of an aluminum exterior panel including: preparing an aluminum material; anodizing to form pores on a surface of the aluminum material; performing atmospheric-pressure plasma treating, at room-temperature, to improve hydrophilicity of the surface of the aluminum material on which the pores are formed; digital printing of implementing a color and an image on the surface of the aluminum material with improved hydrophilicity; and sealing to close the pores.
Claims14
A method of manufacturing an aluminum panel comprising:
- anodizing a panel including an aluminum material to form pores on a surface of the aluminum material;
- atmospheric-pressure plasma treating the anodized panel, at room-temperature, such that a hydrophilicity of the surface corresponds to a contact angle between water and the surface is 30° of less;
- digital printing an ink on the surface such that the ink is absorbed into the pores;
- and
- forming an aluminum oxide film on the surface such that the aluminum oxide film covers the pores so as to seal the ink inside the pores to thereby prevent separation of the ink from the pores.
