Ink jet recording apparatus and ink jet recording method

摘要

An ink jet recording apparatus of the present invention includes a head, a first light source, a second light source. Liquid droplets of a photo-curable ink composition are applied to a recording medium. After one second or less elapses from the time when the liquid droplets are applied to the recording medium, the liquid droplets are illuminated with light of the first light source. After 0.1 second or more and one second or less elapses from the time when the liquid droplets are illuminated with light of the first light source, the liquid droplets are illuminated with light of the second light source.

主权项

1. An ink jet recording apparatus comprising:
a head that applies liquid droplets of a photo-curable ink composition on a recording medium from a plurality of nozzle holes; a carriage in which the head is mounted, the head being moved in a first direction by an operation of the carriage so as to eject the liquid droplets by being relatively scanned with respect to the recording medium; a first light source and a second light source that are mounted on the carriage so as to move together with the head in the first direction and that illuminate the liquid droplets applied on the recording medium, the first and second light sources being provided at a same side of the head in the first direction; and a third light source that is disposed at a medium downstream side in a medium movement direction of the recording medium, wherein the photo-curable ink composition has a photo radical polymerization property and contains at least one of an acrylic ester series having an acryloyl group, the liquid droplets are illuminated by the first light source and the second light source so that the photo-curable ink composition is cured, the first light source and the second light source are spaced apart from each other so that the liquid droplets are illuminated by the second light source after the first light source stops illuminating the liquid droplets, and after the liquid droplets are illuminated by the first light source and the second light source, the liquid droplets are further illuminated by the third light source so that the photo-curable ink composition is further cured.
