Patent ID: 8339691

Claim:
A profile creation method for creating a color profile, comprising: a determination step of determining whether a medium used for printing contains a fluorescent brightener, based on measured values of the medium; a correction step of correcting measured values of color patches formed on the medium, based on a result of the determination; and a creation step of creating the color profile based on the corrected measured values of the color patches and measured values of an ambient light used in measuring the color patches, wherein the measured values of the medium are values of spectral reflectance obtained by spectrometric measurement of white part in the medium, and the determination in the determination step is performed based on a difference between a highest value of the spectral reflectance and a value of spectral reflectance at a predetermined wavelength, and wherein the measured values of the medium are obtained using a colorimeter without using a special filter which cuts off a short wavelength of less than 500 nm.
