ABSTRACT:
A standard conversion table setting unit establishes a standard conversion table for converting YMCK halftone dot percentage data supplied from an image editor into color image data in a common color space for generating a predicted image under standard output conditions to produce a final image. A differential parameter setting unit establishes differences between the standard output conditions and actual output conditions as differential parameters. A differential conversion table setting unit establishes differences between the standard conversion table and a conversion table for producing a predicted image corresponding to the final image generated under the actual output conditions, as a differential conversion table based on the differential parameters. The conversion table corresponding to the actual output conditions is generated using the standard conversion table and the differential conversion table, and image data to produce the predicted image are generated with the conversion table.
