Digital BW, The Print

Yes, should work OK.  Here is what I do to get a neutral curve.  If you 
don't want glop to follow the light inks then just edit the LK curve in 
the .quad file to a straight line or whatever else you want.

# Uses the MIS UT7 inks in the following positions:
# K - MIS Eboni black
# LK - MIS Glop
# C - UT-PKN
# LC - MIS UT7 LM gray
# M - MIS PK
# LM - MIS UT7 LC gray
# Y - MIS UT7 Y Sepia
