Dave,

You need to PRINT the QTR-21-random test chart. Then read with the Eye One.

Don't know if you are on Windows or Mac. Mac has text paper profiles that are easy to 
edit.

To re-linearize delete the complete line like this in the original paper profile: 
LINEARIZE="0.029 0.077 0.141 0.217 0.299 0.379 0.469 0.554 0.643 0.732 0.816 0.891 
0.969 1.048 1.133 1.219 1.308 1.390 1.469 1.569 1.664 "

Turn off all color management in Photoshop and print test chart using QTR. Let dry for a 
few hours or use a hair drier for a few minutes and read with Eye-One. Copy and past new 
linearization output from Eye-One/QTR script into paper profile.
