Abstract:
1. An ink-jet printing apparatus using a printing head capable of ejecting ink from ink ejection portions to print on a printing medium while the printing head moves in a first main scan direction and a second main scan direction opposite to the first main scan direction, wherein the printing head is able to eject ink containing an ultraviolet curing agent, comprising: a first ultraviolet radiation unit, positioned at a side of the printing head that leads when the printing head moves in the first main scan direction, for radiating an ultraviolet light to the ink adhered to the printing medium while moving with the printing head; a second ultraviolet radiation unit, positioned at a side of the printing head that leads when the printing head moves in the second main scan direction, for radiating an ultraviolet light to the ink adhered on the printing medium while moving with the printing head; and control means for controlling said first ultraviolet radiation unit so as to radiate the ultraviolet light and said second ultraviolet radiation unit so as not to radiate the ultraviolet light when the printing head ejects ink while moving in the first main scan direction, and controlling said second ultraviolet radiation unit so as to radiate the ultraviolet light and said first ultraviolet radiation unit so as not to radiate the ultraviolet light when the printing head ejects ink while moving in the second main scan direction.
