  • Patent number: 10421235
    Abstract: A three-dimensional object is made of curable ink and includes a color layer serving as an outer surface. The color layer includes color ink and clear ink filling a space between dots of the color ink. A rate of the color ink to the clear ink decreases toward an outer side. With this configuration, the clear ink ensures diffusion of light beams reflected by dots of the color ink in a portion close to the outer side of the color layer. This ensures improved granular texture on the surface of the three-dimensional object.
