1. An ink-jet recording apparatus, comprising:
a printer head which moves relative to a table on which a medium is placed, and which ejects ink onto the medium while moving relative to the medium in a main-scanning direction, wherein the medium moves in the sub-scanning direction by a predetermined width in the sub-scanning direction which is defined as an one unit during printing by the printer head, and the printer head performs printing with the one unit set as one PASS; irradiation means having a plurality of light-emitting diode modules for performing exposure with respect to the ink ejected onto the medium to cure the ink while moving together with the printer head in the main-scanning direction, wherein a temporary curing is performed by adjusting an amount of light from the light-emitting diode modules for exposure at a same PASS as the PASS at which the ink is ejected from the printer head, and a full curing is performed with respect to the ink on the medium that has been temporary cured by a previous PASS by exposure in an amount of light which is larger than the amount of light during the temporary curing in the previous PASS; and each of the light-emitting diode modules has a plurality of light-emitting units which are provided to the irradiation means at a position near the medium, which are plurally arranged at least in the main-scanning direction, and which are divided into a plurality of areas in accordance with an arrangement position with respect to the irradiation means to adjust an amount of light during light emission for each of the areas, wherein in each of the plurality of light-emitting diode modules, an outer peripheral portion corresponding to a strong light amount portion in a plan view of the light-emitting diode module has a larger amount of light than a center portion corresponding to a weak light amount portion of the light-emitting diode module, and the amount of light emitted to a portion of the medium, which faces the weak light amount portion, from other than the weak light amount portion, becomes larger than the amount of light emitted to another portion of the medium, which faces the strong light amount portion, from other than the strong light amount portion, and the medium in an irradiation range from one of the light-emitting diode module is irradiated with light in an uniform amount of light. |
