Thanks Roy, this is starting to sink in. I've been confused between 
display profiles & print profiles. Photoshop doesn't help much in this 
regard as both types of profile appear in the same dropdown lists 
without making the distinction.

So QTR - Gray LAB & GG2.2 are working space or display profiles whereas 
QTR - Gray Matte Paper for example, and profiles created with 
QTR-Create-ICC are print profiles.

To extend my tests and print with a print profile, once I am ready to 
print, I should convert the files to, say QTR Gray Matte paper and see 
what happens there? (I am on a PC printing with QTRgui).

Thanks again
