Abstract:
1. A print controller controlling a print process in which black ink having permeability to a recording medium and chromatic color ink having permeability to the recording medium different from the permeability of the black ink are used to form an image on the recording medium, the print controller comprising: an acquiring unit that acquires image data having a plurality of sets of pixel data, the image data representing an image including pixels, each set of pixel data corresponding to one pixel and indicating a gradation level; a subject pixel setting unit that sets, as a subject pixel, one pixel that is in the image and that satisfies a first condition that the pixel is a black pixel expressing black, a second condition that a plurality of peripheral pixels that are located adjacent to the pixel and that surround the pixel include at least one chromatic pixel expressing chromatic color, and a third condition that the gradation level of black changes discontinuously between the pixel and at least one of the at least one chromatic pixel, a discontinuous change in the gradation level of black being defined by a difference between a black component value of the pixel and a black component value of the at least one of the at least one chromatic pixel is greater than or equal to a predetermined first value; and a bleed suppressing unit that executes a bleed suppression process to a set of pixel data corresponding to the subject pixel to suppress bleeding of the black ink on the recording medium only when the set of pixel data corresponding to the subject pixel satisfies all of the first condition, the second condition, and the third condition.
