Striped variation is restrained from occurring in a printed image which is printed by an inkjet printer. An RIP 40 includes, a dot displaced quantity detecting section 41 detecting a displaced quantity of a hitting position of ink, a contour detecting section 42 detecting one pixel corresponding to the contour, a dot size setting section 43 setting a dot size of each pixel to be larger than a resolution pitch based on the displaced quantity detected in the dot displaced quantity detecting section 41 and the pixel corresponding to the contour detected in the contour detecting section 42, a density setting section 44 setting an ink density of a dot to be made thinner, and a print data creating section 45 in which number of times of ejection and ink droplet amount of the ink droplet are calculated for each pixel based on the dot size of a pixel set in the dot size setting section 43 and the ink density set in the density setting section 44 to create print data for forming dots on a recording medium with the dot size set in the dot size setting section 43. |
