    摘要： [Means for Resolution] A controller of a three-dimensional inkjet printer superimposes noise on a control signal which drive controls an A drive motor 46 and B drive motor 46, and based on the control signal on which the noise is superimposed, drives the A axis drive motor 45 and B axis drive motor 46. Because of this, a medium M revolves while fluctuating minutely in an A axis direction and rotates while fluctuating minutely in a B axis direction, so that the landing positions of ink droplets ejected from an inkjet head 20 deviate non-uniformly in a main scanning direction and sub-scanning direction overall. Because of this, the deviation of dot positions becomes visually inconspicuous, and unevenness in print density decreases.

    摘要： [Problem] To reduce unevenness in print density.
    [Means for Resolution] A three-dimensional inkjet printer has a medium holding portion 40 which holds a medium M on which a vibration generator 50 which applies vibrations to the medium holding portion 40 is mounted. Then, vibrations are generated from the vibration generator 50 when ink droplets are ejected from an inkjet head 20 by relatively moving the medium holding portion 40 and inkjet head 20 while rotating the medium holding portion 40. Because of this, the medium M held by the medium holding portion 40 vibrates, and the landing positions of ink droplets ejected from the inkjet head 20 deviate non-uniformly overall. Because of this, the deviation of dot positions becomes visually inconspicuous, and unevenness in print density decreases.

    摘要： An image shape transforming device 10 according to an embodiment of the present invention transforms a shape of an image for a 3D printer that prints on the surface of a medium that has a three-dimensional shape print band by print band. The image shape transforming device 10 includes a relative curvature calculating means 11 for calculating a relative curvature for each print band relative to a reference print band among the print bands, and an image scaling means 12 that scales the image of each print band according to the relative curvature of the print band.
