Abstract:
A liquid discharge control apparatus includes a discharge control unit that controls the discharge of the liquid through the nozzle. In the case that the discharge control unit allocates, to a first nozzle, the pixel of a first ratio in a pixel column that represents one raster line, and allocates, to a second nozzle, the pixel of a second ratio in the pixel column, and in the case that one nozzle of the first nozzle and the second nozzle is an abnormal nozzle, and the ratio of the pixel in the pixel column allocated to the one nozzle is more than or equal to a predetermined ratio with respect to a total of the first ratio and the second ratio, the discharge control unit increases the ratio of the pixel in the pixel column allocated to the other nozzle of the first nozzle and the second nozzle.
