Digital BW, The Print

After tweaking the install procedure for Fedora I'm printing!
The output is still not as good as what I was getting from PS/Paul
Roark curves and certainly doesn't match my 2200/IP setup.

I'm comitted to fine tune my QTR install though I would be greatly
indebted for the clarifications on the following:

1. I'm a little shaky on manually pdating the ppd. What seems to work
is to gedit /etc/cups/PPDS/QUAD1160.ppd to include 4 curves (as per
Roger's suggestion) in bot Curve1 and Curve2 area (I only have
1160-vm-gray.txt and 1160-vm-toned.txt. No -calib... does it matter ?). 
I don't run rin-quadprofile, go straight to Webmin, select -grey for
Curve1, none for Curve2. Save.
I can print a graywedge more or less OK.

How do I verify that the curve is loaded ?
If I use Webmin it still shows -none.

2. If I need to run run-quadprofile, when should I do it and why ?

3. I'm using UT inkset on glossy papers using 1160-vm-grey. 
Should this produce reasonable results for starters ?
It looks like too much ink is laid out and the transitions are not smooth.

4. Since the only printing method I can use is Dave Wroblewski's qpr I
don't think I can start working on calibrating my printer/inks/paper
combination. Is this correct ?

5. Is there a version of qtcups available for download which would
work on Fedora ? I tried to use one from redhat distribution to no
avail (works for the regular 1160 driver though).

If you feel that I can brush up on this without eating the bandwith on
this group pls send me in the righ direction.

Thanks,

Roman
