QTR-Quadtone RIP

David,

Embedded profiles are ignored by QTR.  It does not "do" color 
management.  It simply looks at the raw numbers in the files and 
outputs the data.  

There are two or three popular ways to get a print that matches your 
screen.  

1.  Use Roy Harrington's Gray Lab profiles.  Edit in Gray Lab until 
you like the way the image looks.  On a PC, you then convert your 
finished file to the Gray Matte profile for printing on matte papers, 
or the Gray Photo profile for glosy, luster, semigloss papers.  This 
remaps the tonal range to fit nicely on these papers.  Use BPC and 
Perceptual intent when converting.

2.  Use Carl's soft proofing profiles.  You print a 21 step grayscale 
and create a small profile with your spectrophotometer and profiling 
software, just like you would any profile.  When you soft proof in 
Photoshop, click Preserve Color Numbers.  You will see both the tonal 
range and coloration of the profile.

3.  Some people create dot gain curves in Photoshop to visually match 
the screen display to the printed output.  Paul Roark's site has this 
procedure written out.

I believe Carl's profiles are cross platform.  He has just compressed 
the file using Stuffit.  Should work.
