Searching the archives for "silk screen emulsion" (no quotes) brings
up some useful matches.

I just cropped and removed extraneous images from a file someone had
uploaded previously of his tests using silk screen emulsion as photo
etch resist. He just brushed it on. However, as per his later
messages, which emulsion you use is very important. Not all will stick
to copper.
