Abstract
A printing apparatus includes a print head that is able to apply light-blocking ink that blocks light and metallic ink that creates a metallic look on a printing medium, a metallic look control unit that determines the ink amount per unit area of the light-blocking ink that the print head applies based on the created metallic look, and an ink application control unit that controls the print head, applies the metallic ink and the light-blocking ink based on the determined ink amount on the printing medium, and laminates the metallic ink and the light-blocking ink such that the side that is viewed has the metallic ink.
