ABSTRACT:
An image processing method generates a halftone image by forming a halftone dot represented by a set of one or plural output dots corresponding to an intensity of an input image signal while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of a halftone-dot portion. The image processing method includes holding in a predetermined storage medium halftone-dot profile data for forming the halftone dot corresponding to the intensity of the image signal and gap-size profile data representing a size of a set of the non-output dot; and generating the halftone dot comprising a gap having a size based on the gap-size profile data, a size of the halftone dot being based on the halftone-dot profile data.
