1. A profile creation method for creating 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 comprising the steps of:
(a1) acquiring colorimetric values of patch images included in a plurality of color chart sheets outputted from at least a first printer;
(a2) acquiring colorimetric values of patch images in a color chart outputted from a second printer;
(b) creating a color conversion profile for the second printer from the colorimetric values acquired at the step (a2) 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 at step (a1); and
(c) when an amount of color chart sheets outputted from the first printer increases by a predetermined amount, creating a new color conversion profile for the second printer from the colorimetric values acquired at the step (a2) by using a calculation formula according to the degree of the variation obtained from the color chart sheets after the increase.
