Patent ID: 8814291

Claim:
A nail printing device comprising: a printing unit which includes a printing head that applies ink on a print target surface in accordance with a printing mode, and a control unit which controls the printing unit, wherein the control unit sets the printing mode to one of a nail printing mode and a printing medium printing mode, wherein in the nail printing mode, the control unit: (i) sets a surface of a nail portion as the print target surface, wherein the surface of the nail portion has a curve-shape such that a center portion of the surface swells more than both end sides of the surface along a width direction of the surface of the nail portion, and (ii) creates first nail printing image data for printing on the surface of the nail portion corresponding to the curve-shape of the surface of the nail portion, wherein in the printing medium printing mode, the control unit: (i) creates second nail printing image data for printing on the surface of the nail portion, (ii) sets a planar surface of a printing medium as the print target surface, (iii) performs thinning correction to the second nail printing image data to generate corrected image data, and (iv) controls the printing unit to apply ink on the planar surface of the printing medium corresponding to the corrected image data generated by the thinning correction, and wherein the thinning correction is performed such that a density of ink applied on the planar surface of the printing medium corresponding to the corrected image data is similar to a density of ink when the surface of the nail portion having the curve-shape on which ink is applied corresponding to the second nail printing image data is seen from above.
