Re: muddy gum print--help?
Charles, I think it depends a lot on the paper how the Gamblin PVA
behaves. On Arches bright white (a very crisp-surfaced paper) I
found it rather shiny and almost like a plastic coating at full
strength, but on a more absorbent paper, I gather it soaks in more
and gives a more matte appearance. So you really have to see how it
works best on your paper. Good luck,
Katharine

Charles,
The person who Jim refers to as using the 1:1 dilution of Gamblin
PVA Size uses several coats at that dilution, letting it dry for a
few minutes btw each coat. He uses the Gamblin because he has had a
double lung transplant! He gets beautiful results...
Supposedly, the undiluted Gamblin will give a slight sheen to the
print, while the 1:1 dilution will be more matte...
I have a bottle and haven't used it yet, mainly because I haven't
started printing gums or gum-overs...yet...yet...;-)

Jim:
Sorry about the confusion. I'm using standard liquid gum.
The 50/50 water mix was determined empirically to be thick enough
to coat and thin enough to measure with reasonable repeatability
in an eyedropper. It is possible that I could or should use a
thicker gum, but this coats evenly. Charles Portland Oregon
