Abstract
A printing apparatus including a print head that performs a printing pass that ejects a photocurable liquid onto a printing medium while being displaced in a main scanning direction each time the print head is displaced in a sub-scanning direction by a displacing amount of a sub-scanning operation, a first irradiation unit that follows the print head displaced in the main scanning direction while radiating light onto an area that is larger than the displacing amount of a sub-scanning operation, and a second irradiation unit that irradiates the light towards an area where irradiation of the light has been completed by the first irradiation unit. Furthermore, an integrated quantity of light of the first irradiation unit is reduced and an integrated quantity of light of the second irradiation unit is increased, in accordance with the increase in the set number of printing passes to be carried out.
