In the second example, the correction is made to K45, which is not
located at the base point of the color table. Changes to the corrected
color will have less than 100% effect on this color (about 88% only),
because the effect is interpolated from that of the K40 and K50 value.

Using the LOAD button in the COLOR VALUE CORRECTION dialog (see Fig.
18-5), you can open files containing CMYK and/or Lab values. All files
can be used to conveniently select the colors to be matched by the
printer – instead of using the sliders on the left (see Fig. 18-10).
The following color value files are supported:
• Reference files (*.REF, *.TXT)
Files that describe a particular test chart, i.e. the CMYK values of the
individual color patches.
