Re: Freeform gum (Re: Gum printers in UK (Re: Scott McMahon gumworkshop, September
Actually, when I mused that maybe this isn't a freeform gum, maybe
it's done with "a separation negative of some sort," I wasn't
thinking just of tricolor separations but of anything that separated
the tones into a separate negative, in addition to a possible color
separation. But certainly c would work too. The question was, if
it's a freeform gum, how was the color separated? None of the
answers below assumes a freeform gum, but all are certainly possible
ways of achieving it with "a separation negative of some sort;"
even "c" uses the negative to separate the colors rather than
separating the colors in application or development. (When
tentatively defining freeform gum, I was only thinking of separating
the colors by selective application; I hadn't thought of separating
the colors in development as Damiano did; that's very well done).

Not that I think I have a better idea but will list some solutions
look probable to me:
a) Making duotone (or tritone, or quadtone) separations. My color
/ duotone knowledge is limited, so I can't say if one could design
duotones profiles giving results similar to the image in question...
b) As Katharine says -> making tri-color separations... (Coloring done
in image editing program...)
c) Using a fairly high contrast negative and printing the highlights /
midtones and shadows in different colors. Shadows could have been
printed using a fairly opaque color or a color that gives green when
printed over earth colors - if possible... (Again, I don't know if
are such opaque greens - or if there's a color which will give green
when printed over earth colors... A transparent blue?)
I would first try (c) then (b) and (a)...

Subject: Freeform gum (Re: Gum printers in UK (Re: Scott McMahon gum
Hence David's question about how one would get such a nice separation
of the green, in the absence of the use of color separations. One
possibility is that maybe that image isn't a freeform gum but is done
with a separation negative of some sort. Otherwise, I don't know
how it could be done.
Hope that's helpful, and as I said, I hope if someone has a better
idea, they'll say so.
