Digital BW, The Print

In confirmation of what Roy has suggested here, I have actually had a 
very good result using VFA with the Cone-supplied curve for HPR and 
an ICC (QTR Create ICC) profile on top of that.  I am also using ICC 
profiles for even the Cone-curved papers because this corrects small 
differences in the individual printer, etc.

What was not obvious to me (but explained by Roy and others on the 
board) is that before printing, the image needs to be *converted* to 
the ICC profile and saved that way.  (With PS/Epson driver, this 
conversion occurs automatically upon printing.)  The same image can 
thus be used for any paper simply by converting to the profile for 
that paper.  It doesn't matter what the embedded profile or workspace 
is before conversion.
