Abstract
A printing device that prints an image onto a printing medium using a printing head that includes a plurality of nozzles each being capable of dot formation to the printing medium. The printing device includes: an image data acquisition unit that acquires image data showing pixel values of M (M≧2) for the image; a displacement amount information storage unit that stores information about an amount of a displacement observed to the printing medium by each of the nozzles between an actual dot formation position and an ideal dot formation position; a printing data generation unit that generates printing data including information about dot formation details based on the acquired image data and the displacement amount information for each of the pixel values, and for use as the information about the dot formation details, generates information about reducing degradation of printing image quality due to a banding problem caused by the displacement between the actual dot formation position and the ideal dot formation position, and exercises control over generating the degradation-reducing information based on the displacement amount information; and a printing unit that prints, based on …
