PURPOSE: An image-processing apparatus, a print control apparatus, an image-processing method, and a recording medium are provided to convert tone image data into a form expressed by the dot on-off state, and to rapid conversion of image data with sustained quality. CONSTITUTION: The print system comprises a computer(10) as the image-processing apparatus, a color printer(20), and the like. Upon receiving tone image data concerning RGB color images from a digital camera, color scanner, or other video device, the computer(10) converts these image data to print data that can be represented by the formation of color dots printable by the color printer(20). The RGB tone image data can also be compiled by the computer(10) with the aid of various application programs. The printer driver(12) comprises a plurality of modules, which include a resolution conversion module, a color conversion module, a tone number conversion module, and an interface module. The tone number conversion module converts the tone image data to an expression format based on the dot on-off state. The types of processing performed by the other modules will be described hereinbelow. The color printer(20) prints color images on a print medium by forming color-ink dots on the basis of the print data converted by the modules.
