| Loris,
I wonder if one could use Gretag/Macbeth and build a profile to neutralize the colors in a gum print?
You would have variables such as which pigments you use and how much of each pigment, but it might be interesting to try.
I don't think it would make all pigment sets look the same after profiling, but then that's part of what people like, the results they get with different sets of pigment容ach having its own look.
Best Wishes,
Mark Nelson

the blue. Since the spacing between PY42/43 and PV19 is fine (albeit in
the opposite direction of what McEvoy suggests; a yellow closer to the
magenta instead of a magenta closer to the yellow), and PB15:3 is right
opposite to them. If that doesn't give me acceptable results, then will
try with a brighter / colder yellow and a redder magenta. For the moment I
like PY42/43 because if gives nice / contrasty gradation gradations unlike
the brighter yellows (I simply can't see the gradations when printing with
a bright / transparent yellow).
