Abstract: To generate a dot pattern whose deterioration of a feeling of granularity, density unevenness, and streaks are unlikely to be recognized visually by more effectively suppressing a change of an overlap of ink droplets on a printing medium. Halftone image data representing a dot pattern of each of two or more kinds of dot different in density reproduction is acquired. Then, in a case where there is a possibility that the contact state between dots changes due to a landed-dot shift of ink in a plurality of specific dots on a condition that dots are formed in accordance with a dot pattern in the halftone image data, the plurality of specific dots is replaced with dots of another kind whose number is less than or equal to that of the plurality of specific dots.

Abstract: Provided is quantization processing that can reduce color development defect due to dot overlapping and can output an image with reduced granularity when the image is printed by using multiple kinds of colorants. To this end, dot arrangement information for a colorant for which dot arrangement is already determined among multiple kinds of colorants is acquired for a predetermined region of the image, and an evaluation value of each pixel included in the predetermined region is derived based on the arrangement information. In addition, for the predetermined region, a target value for a predetermined colorant for which dot arrangement is yet to be determined is derived based on the image. Then, whether or not to arrange a dot of the predetermined colorant in the predetermined region is determined based on the target value and the evaluation value.
