  • Patent number: 12291041
    Abstract: An inkjet printer includes an ink head, a carriage, and a first discharge controller. The ink head discharges photo-curable ink onto a recording medium. The ink head includes a colored ink nozzle group to discharge colored photo-curable ink, and a transparent ink nozzle group to discharge transparent photo-curable ink. The carriage is equipped with the ink head. The first discharge controller is configured or programmed to, when either one of the carriage and the recording medium makes a single movement, cause the colored ink nozzle group and the transparent ink nozzle group to discharge the colored photo-curable ink and the transparent photo-curable ink, respectively, onto a predetermined region so as to form a colored image and a texture image. The texture image includes the colored photo-curable ink and the transparent photo-curable ink that overlap with each other.
