A colorimeter of a profile generator calorimetrically measures a color chart after elapse of a sufficient period of time from printing of the color chart, thereby producing post-dry-down colorimetric values. The colorimeter also calorimetrically measures certain patches selected from the color chart immediately after printing thereof, thereby producing pre-dry-down calorimetric values. Colorimetric value differences between the post-dry-down colorimetric values and the pre-dry-down colorimetric values are calculated. Using the calorimetric value differences and the post-dry-down calorimetric values, device-dependent data are converted into colorimetric values, which represent pre-dry-down device-independent data. The colors of a print prior to dry-down are predicted based on such converted colorimetric values.
