Abstract:
1. A printing apparatus that performs printing image on a print medium by carrying out a relative movement between printing elements for forming dots on the print medium and the print medium, said apparatus comprising: a relative movement operating unit configured to carry out the relative movement so as to make the printing elements corresponding to the same color opposed to a same pixel area in a pixel of the print medium, on which a dot is formed, a plurality of times, a plurality of printing elements being sequentially opposed to the same pixel area; and a dot data generation unit configured to generate dot data used for printing dot on the print medium in the relative movement based on gradation levels of a plurality of image data of the image corresponding to a plurality of pixels by using a dot arrangement pattern representing an arrangement of dots in the pixel areas for each gradation level, the dot arrangement pattern determining whether or not to form dots for each pixel area and holding information for specifying which printing element is to be used for forming forms the dot on a pixel area in the plurality of printing elements.
