Digital BW, The Print

Steve,

I printed your calib page with the profile I posted (on both Ilford 
Smooth Pearl and  Kirkland Glossy) and here are the comparable data to 
what you just posted:

Kirkland Glossy:
LM/LC at 45/45 LK 10 (glop)
50% patch L 61.0, a 0.7, b -2.0
100% patch L 43.3, a 1.3, b -1.9

Ilford Smooth Pearl:
LM/LC at 45/45 LK 10 (glop)
50% patch L 61.9, a 0.9, b -1.9
100% patch L 44.3, a 1.4, b -2.0


Quite different from your results - are you using the UT7 LM and LC 
gray ink?  Note that I did not edit the LK curve in the cal .quad file 
so glop (LK) was applied in the combo print (LK/LM/LC).
