Digital BW, The Print

Well according to the labels on the bottles I have the right inks but yes I
really wonder if I got a wrong batch.  Here the partition values I have:

Warm 44
Sepia 40
Neutral 34
Cool 24

One (big) qualification:  I am using UT2 LM medium grey as my "light warm
grey" in the LC slot.  My understanding is that this is the same as UT7 LC
ink.  I am also using UT2 sepia toner which I understand to be the same as
UT7 sepia toner.

On this basis my inks set up should be the same as yours but with the inks
in a different order:

K is PKN
LK is glop
C is MIS PK
LC is UT2/7 light warm grey
M is Eboni
LM is UT2/7 light cool grey
Y is UT2/7 sepia toner

Looking at an old calib page from the UT2/FSN days I can clearly see that
the light warm ink I am using is lighter than the "dark warm grey".  I have
not opened the bottle of UT7 M.
