如下是Curve4中，对VPR的说明，我粘过来，谁能给我解疑？
VPR applies G7, TVI or SCTV calibration curves to measured data to simulate printing with perfect calibration. This saves time and materials, reduces print unevenness, eliminates run-to-run differences, and delivers virtually perfectly-calibrated measured data.

In data to be Curved load a file containing CMYK plus (optionally) Lab, XYZ and/or spectral values,
If the data to be Curved file is CMYK-only, in Training Data load a file containing CMYK and color values,
For a characterization target (TC1617,IT8.7/2,HC2052,ECI2002,etc.) leave Training data empty.
For small target(e.g. P2P), load characterization data (if available) in training data.
To apply curves to CMYK values without changing color values, select Curve CMYK Percentages.
