1. Laser print a reverse image to tracing paper. It's less problematic than overhead transparency sheet through the fuser and still gives a crisp result.
2. Use photo-resist on the PCB - either pre-clad PCBs or buy the liquid, sponge on and dry (in a dark room).
3. Put the printed sheet face down on the board and expose either in the sun or in a UV light box with vacuum table, they're not stupidly expensive if you have a few boards to do.
4. Etch and drill.
I get consistent results with tracks and separations down to 0.005" using this method.
Well, I say "get" but what I mean is "got". With the low price and fast turnaround of places like OSHPark, SEEED and a bunch of others for boards with through hole plating, tented vias, silk masks, 4 layer or more boards etc I don't bother stuffing around with home PCB manufacture any more - the results are always going to be inferior and (in terms of time etc) way, way more expensive than shopping it out.
