transparencies film work great with inkjet printer. That's what i use here. Set your printer to the best resolution mode... yeah slower but better. I tried laser printer in the past. i gave up, sometimes the toner don't do a nice and perfect job on 10-12mils traces. Home made Thru-hole plating would be nice... but not a trivial thing. Sure there's some rivet kit available here and there... but it's a little bit expensive for what it worth. Better to outsource your PCB to some cheap PCB fabs. Good luck!

Inkjet? Really? I didn't think that worked at all! I tried the 'Press-n-Peel' method awhile back, used the good laser printer at OfficeMax, was really careful and all that. But it seemed like my problem was with the toner.
Does the ink actually dry on the transparency or do you have to be fairly careful with it (i.e. don't bend it, etc.)? How small are you able to get reliably on the traces and circles and the like?

I've never had enough guts and patience to try the press and peel method. Yeah i like dealing with chemicals and black-rooms

Depending of your printer, you won't need to care about film handling. I'm a Canon printer fan. I use a IP4200. I print the film, wait 20-30 second (just for safety sake) then do the exposure job.

The ink stick on those film really well, you can bend them as you wish. no real problem. Just make sure you select the right film model for the right printer brand and you're in business.

I'd compare few film brands to see if there's any difference between them. Not really. I use those from staples.

PCBs brand make a difference. Here we can have those from C.I.F (circuit imprimé francais) or MGChemicals. By far, i prefer MGChemicals. Hassle free, work all the time.
