Abstract:
Provided are a non-transitory recording medium, a scanner profile correcting method and a printer. A printer outputs a color chart including color patches for correcting a scanner profile. A hardware processor of the printer or a device in a printing system obtains measured RGB values and measured colorimetric values of the color patches. The hardware processor calculates, for each K component value, two kinds of correlation of each of R, G and B component values with lightness component values, by using a scanner profile, and the measured RGB values and colorimetric values. The hardware processor calculates, for each K component value, a difference in each of R, G and B components between RGB values given from the first correlations and the second correlations, both correlated with each of lightness component values, and creates correction tables for R, G and B components, to be used for correcting the scanner profile.
