There's an old thread from the sci.electronics.design newsgroup at

http://engrss2.unl.edu/ee/eeshop/pen.txt

concerning ink suitable for etch resist. One guy was able to get it to
work in a pen plotter. Inkjet would be an interesting development. I
wonder if anyone has tried ALPS dry "ink" (actually wax, I think) as resist?

A regular Sanford Sharpie marker does well for hand-drawn etch resist. It
is the pen that Radio Shack includes in their DIY circuit board kit.

Best regards,
