Printer provided with irradiation device to irradiate printing object with light for curing ink deposited thereon

A printer comprising:

• a platen configured to support a printing object and to move the printing object in a first scanning direction;
• a head configured to move in a second scanning direction relative to the printing object supported on the platen, the second scanning direction crossing the first scanning direction, the head being further configured to eject light-curable ink onto the printing object supported on the platen;
• and
• an irradiation device configured to move in the second scanning direction relative to the printing object supported on the platen, the irradiation device being further configured to irradiate light onto the light-curable ink deposited on the printing object supported on the platen,
• wherein the irradiation device includes a first light source configured to emit light having a first wavelength, and a second light source configured to emit light having a second wavelength different from the first wavelength, and
• wherein the first light source and the second light source are disposed on one side of the head in the second scanning direction.
