Hi David, et al,
Joe's description above is the best simple description I've ever heard
of an ideal gum negative, and beats what I usually say, "In my
experience the best negative for gum printing is fairly thin" all
hollow.

However, though it's hard to guess from the description what's going
on, if it's what it sounds like, that you're not having any luck
producing a gum image at all, I would say that it's probably not the
negative that's your problem. In my experience, while you can change
things about the tonal scale of the print by changing the negative, I've
never seen a negative that won't print a gum image, and I would guess
I've used about as wide a range of negative types as anyone, ranging
from laser printer negatives to in-camera negatives to cliche-verre
(drawn) negatives.

So I guess like Dave I'd like more information about what your
unsuccessful prints look like; I suspect maybe we could help you more
by troubleshooting the printing process itself.
