Digital BW, The Print

ANY inks can be used with QTR.  It is up to you to decide which inks will be
used to make up the greyscale curve.  There is nothing stopping you from
having a purple scale if you wanted if you decided to make a scale with
purple inks.  So go through the normal process with the FSN, choosing how
and which inks you want to make the particular greyscale and in which order.
RE your input/output/blackpoint issue I strongly recommend letting the QTR
ICC profiles do that as described.  You'll get an accurate mapping of the
bkpt and points in between.  The average profiles that are provided for
matte and photo paper respectively are good enough for almost all such
papers.
