Abstract:
1. A profile generating method implemented by a computer, comprising: a first acquisition step of acquiring a spectral transmittance and a spectral reflectance of a color chart serving as a printed object formed on a light-transmissive medium; a second acquisition step for acquiring a spectral distribution of a transmissive light source and a spectral distribution of a reflective light source, which act as observational light sources for the printed object; a calculating step for calculating a colorimetric value of the color chart in an observational environment in which the transmissive light source and the reflective light source coexist, using the obtained spectral transmittance of the color chart, the obtained spectral reflectance of the color chart, the obtained spectral distribution of the transmissive light source, and the obtained spectral distribution of the reflective light source; and a generating step of generating a print profile based on the calculated colorimetric value of the color chart.
