Provided are a computer readable recording medium with a scanner profile correction program installed, a scanner profile correcting method and a printer. The device in the printing system acquires RGBvalues and color values obtained by measuring the color patch for scanner profile correction, wherein the scanner profile correction color patch includes a K patch group including K as a 0% patch anda gray patch group in which CMY values of the patches of the K patch group are set to substantially the same value. The method reads a pre-made scanner profile from the storage device, calculates a correlation between each element of RGB and a brightness element of the color value for each K value, and corrects the measured value of the color patch according to the scanner profile. The method calculates the correlation between each element of RGB and the brightness element of the color value for each K value, and calculates the difference of the brightness element of each element of RGB withrespect to the color value for each K value according to the calculated two correlations. A correction table for correcting each of R, G, and B of the scanner profile is created based on the calculated differences.
