ABSTRACT:
A profile generator determines differences between the standard spectral reflectances of a color chart printed under standard density conditions and the spectral reflectances of a color chart printed while the density of one of the colors C, M, Y, K is changed, and the densities of the other colors are secured to standard densities. When density variations are established, the profile generator generates a print predicting profile using spectral reflectances produced by adding the standard spectral reflectances and the difference with respect to the color whose density has changed. The colors of a print produced when the density of a desired color is changed are predicted with high accuracy using the print predicting profile.
