Method of correcting color conversion data with accuracy

摘要

A reference chart of a target color is generated, and device data corresponding to calorimetric data of the reference chart are determined from color conversion data. A balance chart is generated on the basis of the device data and device data in the vicinity thereof. Patches of the balance chart which are visually color-matched to the reference chart are selected under desired observational conditions, and corrective data based on a deviational quantity between the device data of the selected patches and the device data to be color-matched to the reference chart. The color conversion data are corrected with the corrective data for thereby achieving visual color matching with respect to the target color.
