QTR-Quadtone RIP

I have used (and greatly appreciated) profiles from QTR Create ICC in 
conjunction with standard Epson drivers.  But I am unclear about the 
role of profiles from QTR Create ICC when used in conjunction with 
printing through the QTR RIP.  Does the curve creation and 
linearization of the RIP somehow eliminate or supplant the need for a 
profile?  If so, how is softproofing done in PS?  If the ICC profile is 
still used with the RIP, how is this done?  It seems to me that the RIP 
is simply creating a linearized output (at the printer) and that an ICC 
profile is still needed to characterize that output to eliminate the 
significance of workspace in PS and provide a screen match to print. Is 
it enough to simply use the ICC profile (of the linearized output) for 
softproofing in PS and then print through the RIP without specifying 
that profile?  I'm finding myself coming up short on the concept here.

Many thanks,
Walt

Yes, the profile created with QTR Create ICC can be used to soft proof your
image in Photoshop. It is also used to tie the PS workspace to the
linearized output, as you've described. This is done by converting your
image to the same profile, saving it and then printing using QTR. In CS2 you
choose Edit/Convert to Profile. You have to manually do the conversion. When
printing via the Epson driver your printing software will do this for you.

Hope this helps.

Terry.

I might add that it is useful in this way for any output system, ABW, or RIPs, that take a 
monochromatic file input. I've even used it for gray prep before converting to special 
CMYK ink combos, unique sepia setups for example.
Sometimes the split tone setups require a good softproof as well, the split can occur at an 
unfortunate place in a given image, and it helps to previuw and possibly edit accordingly 
or select different ink setup.
It's a great tool, and even though I don't print with QTR, I felt so bad utilizing it I finally 
had to send Roy his $50. But it was painful, painful...

Sorry about this, but I cant seem to find it.

On http://www.quadtonerip.com/html/QTRiccprofile.html it says it is 
found under the Eye-One Folder - but it completely eludes me...

Assuming you are using a PC and installed QTR in the default location, it
should be in:
	C:\Program Files\QuadToneRIP\Eye-One

It is on my system. I installed the curve creation utilities when I
installed QTR. I have no idea whether the Eye-One folder is installed if you
don't select that option.

If you're on a Mac, then someone else will have to chime in.

Thanks a bunch Tom! Found it  :=)
