Document Type and Number:
Japanese Patent JP4793239
Kind Code:
B2
Abstract:
Disclosed is a print apparatus including a rotating unit rotating a printed object, a print head printing visible information by ejecting ink droplets onto the printed object being rotated by the rotating unit, and a control unit generating ink ejection data based on the visible information and controlling the print head based on the ink ejection data. In the print apparatus, the control unit converts the visible information, which is expressed using biaxial perpendicular coordinate data, to polar coordinate data and carries out dot density correction that applies a correction weighting calculated in accordance with the number of dots per unit area for each dot in the polar coordinate data to a luminance value of each dot to generate the ink ejection data.
