Digital BW, The Print

Cliff,

The UT-RC inkset used a different set of steps from PK to the medium grays
and finally the light grays.  They are 1:1 (denser ink to clear dilution
base), as opposed to the more usual ones I used for the other inksets,
which are usually 30% denser ink, 70% base (or 1:2 if I expect home mixing
without scales).

The UT14-C is a neutral-cool PK that could be used as a starting point for
making an UT-RC type inkset.  MIS does sell the base required: "amber" base
(aka "glop").  So, you could make an inkset that would print similarly.

One thing I asked MIS to do, and they have, is make a UT14-LLC.  This is
not used in the UT14 inkset, but it allows one to have the 3 densities of
both carbon (K4 PK, LK, and LLK) as well as the 3 densities of the UT14
neutralized PKn (Ut14-C, LC, and LLC).

So, you can put UT14-C in the K position, UT14-LC in the M and C positions,
and UT14-LLC in the light ink positions and have an inkset that can be
printed in any hextone (or greater) printer with the Epson driver and
produce a neutral glossy B&W.  You may need to use some curves or other
profiling approach to get the characteristic curve you want (usually
meaning to match the monitor).  If you want warmer, you put some K4 100%
carbon inks in there to warm things up.  The goal here is to have the
inputs digital darkroom ink mixers need to make whatever B&W inkset they
want.  The home darkroom is not dead, it's just become mostly an ink mixing
room.
