QTR-Quadtone RIP

I realise that my last post was a bit long, which does not encourage
responses.  This one is shorter.

I've created a curve definition for EpEnhMatte on my K7 2100 by
mimicking the Cone supplied .quad file.  (I've uploaded the
spreadsheet that I created to do this to the Files section, in case
it's of general interest.)  I've printed out the separation page in
calibration mode with the limit at 100.

Question is, how do I, or indeed can I, set the ink limits using the
calibration printout?  It seems to that the 7 sets of 50 points that I
entered into the curve definition already have limits implicit in
them, non?   Should I solve the too-much-ink problem by setting a
black only limit, or setting a global limit lower than 100?  And can I
determine this from the calibration printout?
