Gum? You mean gelatine I presume?
I have always advised those interested in the woodburytype process to
become fully familiar with the carbon transfer process first. The
"traditional" process involves dichromated gelatin producing a relief that
can then be electrotyped or used to produce an imprint in a block of lead
which can then be used as a matrix.
I know of a few people who have tried this over the years, but not a single
one has been able to show me a print, let alone a decent one. I have
studied it in depth myself and have concluded that it will always be
technically inferior to the carbon process, so why bother?
Then again, for some purposes, with small images that don't have large
white surfaces, the process might be excellent, so I don't want to
discourage anyone.
