Hi James,
You can compare the values of an IT8 scan to the values in the data file that
goes with that IT8, and (within the bounds of the mass measured IT8) you will
get a comparison. Otherwise, you would measure a patches with the scanner,
and with a spectro, and compare those readings.
And no, you don't want the numbers to change with your scanner profile
application, you want the space those numbers are in to change; so they are
the same numbers with different meanings, that view differently.
