gEDA-user: alarm clock update

> What do you all think about inkjetting of resists?

In my case, since I was etching brass, I probably could have just run
the brass through an unmodified printer.  But getting the right inks
and keeping the nozzles clean seems to be a tricky bit for them.
Heck, I have a hard time keeping the nozzles clean with the original
inks.

What I'm contemplating is switching to photoresist.  You print the
pattern on transparencies, photoexpose, develop, and etch.  No
laminating, soaking, etc.  The advantage is that it's easy to line up
transparencies because you can see through them, so doing double sided
PCBs (or in this case, etch brass from both sides) is easier.

I might switch etchants to something see-through too, like the
HCl/H2O2 mix.
