What might be the benefit over gum? In other
words, why the search for other colloids--does gum present problems that another
colloid would solve, for instance?
I have used albumen and it is very fine in texture
but I cannot stand the foetid smell. But I've been told my nose is super
sensitive.
I think using gelatin as a colloid is
probably much hardier to require sawdust development perhaps...and for some
processes (Fresson) that is a good thing.
It was while I was searching for info on screenless lithography
that made mention of it. Seems like a lot of other things are going on in this
process too though. I'm going to give it a try I think. There's a beer and
wine supplier in town which stocks the powder.
Just wondering: in the literature which you read but didn't cite did
you happen to see any compelling reasons to try Maltodextrin? I've
tried all kinds of colloids and, while many harden just fine with
dichromates, most aren't worth the hassle. The primary issue seems to
be one of clearing the unhardened colloid. Many colloids don't seem
to want to wash off the substrate without introducing alcohols or
other solvents.

Has anyone tried Maltodextrin as a replacement for Gum Arabic or is this
idea just goofy? Seems Maltodextrin has many of the same properties as Gum.
