1. An inkjet printer comprising:
an ink head including nozzles to discharge photo-curable ink onto a recording medium;
a light applicator to apply light to the photo-curable ink discharged onto the recording medium;
a carriage equipped with the ink head;
a mover to move either one of the carriage and the recording medium relative to the other one of the carriage and the recording medium in a first direction; and
a controller to control the ink head, the light applicator, and the mover; wherein
the nozzles include:
first nozzles to discharge colored photo-curable ink; and
second nozzles to discharge transparent photo-curable ink;
the ink head includes:
a colored ink nozzle group in which the first nozzles are provided along a second direction perpendicular or substantially perpendicular to the first direction; and
a transparent ink nozzle group in which the second nozzles are provided along the second direction;
the controller includes a first discharge controller configured or programmed to, when either one of the carriage and the recording medium makes a single movement from one side to the other side in the first direction, cause the colored ink nozzle group to discharge the colored photo-curable ink onto a predetermined region while causing the transparent ink nozzle group to discharge the transparent photo-curable ink onto the predetermined region so as to form a colored image and a texture image, the texture image including the colored photo-curable ink and the transparent photo-curable ink that overlap with each other, and
the texture image is formed by the first discharge controller selectively forming irregularities on the colored image in the predetermined region.
