Digital BW, The Print

I've been trying some combinations on my 1270 with UT2 and Ilford
Heavy Weight SemiMatte paper.

My first try was with a EEM profile and like Carl I found about 90% to
be the max.  At that point there was very little Eboni so I decided to 
start from scratch and leave out the Eboni ink all together.   Looking
at the inks separately, both C and M are darker than the Eboni on IHWSM.
So I've got a carbon curve with just M and LM and a neutral curve using
L, LM, C, and LC.  I'm not totally decided how much ink is appropriate
-- it takes a long time to dry --  but I've measured dMax up to 2.30.
I think it might actually to be better down at 2.20 though.

I think it may be possible to do a 3 ink neutral using C if dmax is the
weak point or LC if dots are the weak point.   If this works you
could do glossy/matte and carbon/neutral on the 1160.
