Print density nonuniformity is reduced. In a three-dimensional inkjet printer, a vibration generating device (50), which applies vibration to a medium holding section (40), is attached to the medium holding section (40) which holds a medium (M). Vibration is generated by means of the vibration generating device (50) at the time of jetting ink droplets from an inkjet head (20) by relatively moving the medium holding section (40) and the inkjet head (20), while rotating the medium holding section (40). Thus, the medium (M) held by the medium holding section (40) vibrates, and the landing positions of the ink droplets jetted from the inkjet head (20) are nonuniformly shifted. A dot position shift becomes not visually conspicuous, and print density nonuniformity is reduced. |
