Re: First Tricolor Gum (on aluminum)
Loris,
For a first gum, aside from registration, it is pretty sweet! Colorful and
funky.
What is CaCO3???
I had a student do a tricolor gum senior thesis this semester of Guatemalan
people. I could not believe how intriguing they were. I taught her
tricolor gums, but her gums look nothing like mine. Hers look like, you
know, down in Mexico or whatnot you will see cement walls with flat
whitewashey colors, chalky sort of, almost fresco-like? Her gums all looked
like these flat painted walls. Which, of course, was perfect for the
project. But what it illustrates (again and again) is that the brilliance
of gum is the multiple possibilities of expression.

Subject: First Tricolor Gum (on aluminum)
Hi all,
I just wanted to share my very first tricolor gum print (a test print
actually) on aluminum (actually on any media). I just realized that I set
a too hard target for a beginner because:
1) Working with aluminum is not easy (have to put two coats of acrylic
gesso + two coats of gelatine/CaCO3 mixture - a trick I learned from
Keith Gerling, tonal range and development is quite different from what
is it on paper),
2) Starting with tricolors instead of (more forgiving) multilayer
monochromes may not be the most logical route to take,
3) Aluminum is a stable support/media but this doesn't necessarily mean
that registration is easier and more successful - you have to use some
kind of mechanical registration / you can't register by eye.
4) The whole process is definitely not for the faint-hearted.
Anyway, the print is here:

It's still missing the K layer + as you can easily spot the M layer is
not correcly registered. A very rough print...
Anyway, let me express my immense admiration for people who are able to
make wonderful prints with this process. Respect!
Best regards,
Loris.
