The profile creation method creates a color conversion profile for a printer by causing the printer to output a color chart including patch images having colors corresponding to combinations of values of a plurality of basic colors. The method includes acquiring colorimetric values of the patch images included in the color chart output from the printer; creating a color conversion profile from the acquired colorimetric values by using a calculation formula according to a degree of variation in a color of each patch image obtained from data of colorimetric values accumulated regarding the each patch image; and when the data of the colorimetric values increases by a predetermined amount, creating a new color conversion profile from the acquired colorimetric values by using a calculation formula according to the degree of the variation obtained from the data after the increase.
