Digital BW, The Print

I thought some might like to see a graph of the Lab A & B values that
I'm getting from a 21-step test strip printed with an R220 and the
Eboni-6 inkset on Premier Art Smooth BW paper.  I've posted  a Jpeg of
the Lab A & B graph, as well as small samples from 1600 dpi scans to
compare smoothness.

The base for dilution here was 35% glycerin, 55% distilled water and 10%
Kodak Photo Flo.

Home darkroom work might take an interesting twist here.  Just like the
developer days, different mixes cause different reactions to the tone of
the print -- with pure carbon and just these safe, readily available
substances.  One tradeoff is also smoothness v. tone.   There are
interesing variables here that allow the tuning of a 100% carbon inkset
to a particular paper for a particular tone and printer.
