I can do 12/12 mil tracks, with 10 mils if necessary, using an old LaserJet IIIp to produce the transparencies. I was wondering what is the best any of you can do with a laser printer. I've heard of people getting down to 8 mils with a better printer than mine, and it should be quite easy using photo-reduction from a 4:1 master. There is a PCB co. in the UK that offers 4 mil tracks as standard! I haven't bothered to ask them about prices, though, as I'm sure I won't be able to afford to use them.
