QTR-Quadtone RIP

I just loaded v200 to days ago on a new Vista machine. Before I loaded it, I
could import my old saved setting from the Epson driver and after it I could
not.  New systems new problems, but I am getting very leery of Mike and
unsuspecting changes in Qimage.   I have not had a chance yet to run QTR
test of any kind with Vista. One step at a time.

At the risk of someone thinking that I've become obsessive about this,
I did indeed rerun these tests. Qimage 2008.200 results are at:

http://www.ferdinan <http://www.ferdinand-paris.com/BPC-Qimage_V3.png>
d-paris.com/BPC-Qimage_V3.png

The only one that has changed compared to my V2 histograms from
2008.109 is converting to a generic profile in Qimage without BPC,
which now has a very large amount of black point clipping. I don't
recall seeing any CM changes flagged in the release notes.

So now there is some reverse symmetry. If you convert to a generic
QTR profile in Qimage, you *must* use BPC or else you will see a lot
of shadow blocking. On the other hand if you convert to a custom
profile (or at least mine), then you should *not* use BPC or else you
will get a big dMax loss.

Go figure!
