Why mess around? It's very inexpensive to take you 4X (or whatever ...)
artwork to a photo studio and instruct them to reduce to your required
size film. You want the emulsion (dull) side to face the copper ... and
you likely want to provide positive rather than negative artwork,
depending on your process. Talk to the photographer and show him
samples of a finished board and your artwork ... he'll explain the rest.
The same thing for silk-screens, only take the film to the screen house.

I am trying to get more information on using photographic techniques for
making PCB's. For me I am at the limit of what I can really do with
toner transfer and my 1200dpi printer. I am trying to find information
about printing to transparency and then using some kind of image
reduction. From what I can tell it looks like I would use a photographic
enlarger. I saw a few hints searching google that this could be used for
image reduction, but no real solid information. Does anyone have
suggestions on where I could look for more information on this
technique.
