Profiling

The profiling procedure helps to determine the gamut range of the scanner. This qualitative parameter reflects the deviation of the colors from the required values. As a result of this procedure you get a profile for the scanner that can be used later with any scanned image. Besides the profile proper, you also get numeric values for all the colors of the test target. The following gamut range diagram is based on them:

The gamut range of the scanner in the visible spectrum is identified with a triangle in the diagram.

To build the next diagram I found the difference between the colors of the original target and the scan. The Color Difference value should not exceed 5.0 or the color discrepancies become apparent for a majority of people.
