The white calibration patch reads .12 density on mine, the Black reads 2.28. 

The printed target colors tend to look brighter than what the spectro reading seems to 
show. But this is probably because the "pure" phosphor image on the screen is near the 
full gamut possible, while what is printed on the paper is a lot more limited than that!

While reading the patches you see the comparison of what the paper actually is recording 
for a patch, compared to the full gamut possible for that patch.

This difference is what the profiling program reconciliates, to give you the best possible 
results on the paper being profiled.

On good quality inkjet papers, I find in reproducing paintings, I find I have to "throttle" 
back the saturation of the file to make it match the original art. The beauty of PFP is that 
you can customize your profile to match your desired result by using the sliders!
