QTR-Quadtone RIP

Lou, when you linearize a file in the Windows environment, are you ultimately creating a 
new profile and then soft-proofing AND Printing with this profile (ie, selecting print "Proof" 
rather than "Document")? Or when you linearize do you end up with a new curve 
associated with your specific paper that you can select in "curves" field of the QTR 
dialogue box?
