Abstract

Image data of a color patch is created using a printer profile according to a color conversion method and the image output apparatus 3 prints and outputs the color patch on a storage medium using the image data of this color patch. The color of each color patch recorded on the above-described storage medium is measured using the colorimeter 20, and the matching accuracy calculation section 8 calculates the accuracy (CRI) of color matching using the measurement data of the measurement result. The matching accuracy decision section 9 compares the CRI and a present threshold TH, decides the quality of the accuracy of color matching and notifies the decision result.
