Bill, I think part of is being "missed" here is that most folks doing
tri-color gum are after a "look", not perfection. "Perfection" is far
easier and far quicker and far cheaper in modern manufactured paper.
I've been running a lot of paint tests (and thus a lot of step wedges).
I agree, with three colors I don't get a perfect black. My black tends
slightly blue/cyan, I rather like it! If I wanted a perfect black I
would send the file and $0.29 to Ofoto ;-)

Perfect black (or high DMax) is too highly regarded. Platinum has a
much lower DMax than Silver Gelatin. Cyanotype and gum are even worst.
It isn't perfect black that attracts most of us to alt.

Indeed, this "wanting imperfection" is much of what art is all about.
We just read Christina complaining about the objectionable "cross
hatched grain" on Aristico Cold Press. That is what I love about
Aristico Cold Press, I really enjoy paper that looks like paper (has
some surface to it). Christina likes the Hot Press, I found it too
"perfect". Isn't art fun!
