These were just generic silk screeners-not board shops. several years
ago. I called them, asked specifically about scanning my prints (OK),
asked specifically about screening onto 4X8 media (OK). When I showed
up with circuit traces, I might as well have been wearing a Ronald
Reagan mask.

Example: I needed some 4"X8" copper faced circuit boards screen printed
with my traces. Had all the necessary prints for scanning ready to go. 3
shops looked at me like I just dropped in from Venus. This was in no
way a difficult thing for them to do. Idiots...

PC board shops are all digital, now. Practically none of them have an
enlarging camera, darkroom, etc. like they did in the OLD days of the
1960s, when artwork came in on mylar sheets with black crepe tape and
little pre-cut donut pads. If you can't send them a set of Gerber
files, they just don't know what to do with it. The screen printed
overlay is all generated digitally, the same way. They literally don't
have a procedure or the equipment for going from physical artwork to the
silk screen, anymore.
