Abstract
An image forming apparatus outputs a proof chart in response to an instruction for calibration execution from a user and then a color measuring unit measures the colors of patches on the proof chart. A profile management unit selects, from entries in a base profile DB, a base profile in an entry that has color reproduction characteristics that are closest to the color measurement values of the patches and generates a sheet correction TRC that has an approximation to the color measurement values of the patches when the selected base profile is used. The selected base profile is used as a color conversion parameter in a color management module, and the generated sheet correction TRC is used as a tone correction parameter in a sheet-corresponding correcting unit.
