QTR-Quadtone RIP

Eric,

There is an issue with color management in LR that has not yet been acknowledged by the 
developers.  The basic problem is that LR does not properly render images using QTR 
Create-icc RGB profiles.  I can get around this issue by converting the image to the 
Create-icc profile in CS3 and then print from LR to QTR with color management rurned off.  
I still have to make a round trip to CS3 for final output sharpening before printing so it is 
not currently a big deal to just do the profile conversion at the same time, but if they 
finally add output sharpening capability to LR then it would also be nice to have proper 
color management as well so trips to CS3 could be completely eliminated.  All of this 
pertains to use on a Mac.
