QTR-Quadtone RIP

Got a question regarding printing the Ink Pattern Page ala the
mini-tutorial offered in the files section. 

Quick hardware rundown: Mac OSX 10.4.11, MacBook Pro, Epson 2200,
Spyder3 Studio, Epson UC ink. 

I'm building some curves for Hahnemuhle photo rag and noticed, when
referring to the mini tutorial that one should first print the ink
pattern page using a curve in which you have set calibration to "yes",
the default limit to 100, and deleted the linearize data line. When
I'm in the print dialog for QTR 2.6.1 I can select a curve, then
select Calibration for the mode. The curve appears to remain selected
although grayed out. 

I print this, and, following the tutorial guidelines, define the
limits (in this case K=53%, LK=75%) and add those values to the curve
file. I reinstall the curve, following the same printing procedure
(select the curve, then select the "Calibration" mode and print. The
two prints are identical. Now, does using the calibration mode mean
NOT using any curves (since the selection appears grayed out)? If that
is the case than does that mean the mini tutorial is wrong or out of
date? The process would seem to make sense. You would want find the
ink limit. Print a new page with the limits curve and then find the
density for partitioning. This would not work if the curve is not
applied went printing the calibration page. Am I wrong?
Oh, and I'm not color managing the file. Everything else seems to be
as it should.
Thanks!
