Upon setting of a halftone process of an initial setting, there is such a problem that graininess deteriorates due to an aging change or an environmental change. To solve this problem, an image processing apparatus executes a halftone process on a test image for tone correction and prints the processed test image; forms a tone correction table in accordance with read values from the printed test image; obtains graininess from a read value of a low density portion of a tone correction patch of the test image for the tone correction; discriminates whether the obtained graininess exceeds a predetermined reference level; and changes a setting of the halftone process so as to reduce the graininess when it is discriminated that the obtained graininess exceeds the predetermined reference level.

摘要:
Input print data can assume one of a RGB color space, CMYK color space, and Gray color space. When graphic arts are principally to be printed, data of these color spaces is converted into CIE Color Space XYZ as a standard color space, and data of the standard color space is converted into a CMYK color space according to the Output Profile of a printer, which then prints the converted data. On the other hand, when office documents are principally to be printed, conversion into the standard color space is skipped, and input color space data is directly converted into a print color space CMYK, and the converted data is then printed.
