Claim One:
1. An image processing method that has a function which simulates color reproduction results in accordance with printing target data, which is a reproduction objective of a color to be printed, and that is capable of printing processing with desired color reproduction on the basis of results of the simulation, the image processing method comprising: generating profiles for color reproduction, classified for each of recording papers, from at least one of particular characteristic data of the each recording paper, which is generated on the basis of factors that affect color reproduction, including at least one of a surface-processing condition, a thickness, and a ground color, and particular generation information of the each recording paper, which is obtained by printing plural patch patterns at the recording paper and performing colorimetry of the printed patch patterns; and extracting a profile that matches in at least one of the characteristic data and the generation information, and if no profile matches the at least one of the characteristic data and the generation information, extracting a profile based on judging a degree of matching, wherein the profile is extracted by judging the degrees of matching in the following sequence: matching colorimetry data for primary color density data of cyan, magenta, yellow and black; matching colorimetry data for secondary color density data that is provided by combining cyan, magenta and yellow; matching colorimetry data for process gray density data that combines predetermined densities of each of the colors cyan, magenta and yellow; and matching colorimetry data for gray density data.
