QTR-Quadtone RIP

Scott,

I'm on a PC and con't help answer the Mac ralated questions.  ON my PC, 
I create a profile in QTR (or start with an existing one and delete the 
linearization data).  I use this UN-linearized profile to print a 21 
step grayscale target, which I read with my spectro.  The density or L* 
is loaded (automatically or manually) and makes adjustments to the 
curve shapes to give me a nice smooth tone ramp.  So, the lin data is 
just smoothing out the bumps to the unlinearized file.  

How you do that on a Mac is beyond me, but the result is the same.  And 
since I am on a PC, I cannot print from Photoshop directly to QTR.  I 
have to boot up QTR and print from the QTRgui interface.  

I do sometimes print the linearized 21 step grayscale again after the 
profile is linearized and complete.  I create an ICC profile from the 
linearized print, which I can then use for soft proofing (both tonality 
and color) in Photoshop, but all printing must be done from QTR in the 
PC environment.  The same profile will be used to print in QTR and if I 
have done it all right, the tonality and color should match my PS soft 
proof.
