Hi All. A hektograph is a slightly different process than a spirit
duplicator, so don't conflate the two if you want to be painstakingly,
almost annoyingly exact. Also, the purple-colored sheet for the spirit
duplicator shouldn't really be called a "stencil," because that implies
that it is perforated like a mimeograph stencil. As Mike Biel pointed
out, it is a non-perforated piece of coated paper. It was actually
called a "spirit master" (at least by one manufacturer).
For reference: I had trouble digging up a copy of the (now-defunct)
Dead Media Project working notes on spirit duplicators, but here is
somebody's mirror of them:
The document linked above includes a working note that I contributed on
spirit duplication - I submitted the original article to the Dead Media
list on Halloween, which I thought was _extremely_ clever of me. Get it?
Spirit duplicator. . . Dead media. . .Halloween.. .!! Ok, fine. Groan
if you must.
