Hi, just wondering if anyone knows of a favourite test pattern that can
be loaded into pcb for printing, or any other graphic file that can be
printed, for testing a small scale UV-based PCB etching process.

I'm busy sketching lines in pcb, which makes me wonder who's done this
already!

Thanks,
Matt

I have a few test patterns here: http://www.delorie.com/pcb/

You'll want to look a the "spirals challenge boards" and the bloat
test under "Goodies"

Thanks so much, that's superb. :)

Next, slightly OT, do you or anyone have any favourite photomask
materials/printers?

I print my films on Jetstar premium UV film, with an Epson R280
printer and custom software.
