There are many many ways to take a colour image and convert it to B&W,
including using Channel Mixer.  This choice is completely independent of
QTR.

This is not a recommended method for converting to B&W

This should not be the case.  The black point should be about the same.

You should be using QTR Create ICC to profile it.  Roy's latest efforts will
allow you to proof for hue as well.  He has done an ENORMOUS amount of work
on the next release.  Even when I use AB&W on my 4800 I still convert the
document on-the-fly to a QTR Create ICC greyscale profile that profiles my
AB&W settings.  I can also accurately soft proof all of this before
printing.
