Homebrew PCBs

It looks like the circuit worked so now I'm looking to make more than one or two small boards.  I've managed to arrange the routing so resolution isn't much of a problem.  TT is a bit slow when making more than just a couple of boards.  Has anyone used silk screen methods to apply etch resistant ink?  If so, what screens and inks have been successful.  I know this was commonly done in the PCB industry 20 years ago.  Things have changed over the years and the inks and screens used back then are hard to find.

I've used Naz-Dar ink successfully - they're designedto be 
etch resists - of course, this WAS a goodly number of years 
and a couple of moves ago.  I'm not sure where they might be 
available now.

Thanks for jogging my memory.  I do remember Naz-Dar as a popular ink.  Back when I was wroking in the industry, silk screening was the competitive process so I didn't get as far into it as with photoresists.

I checked the NazDar web site.  They have inks available, but there is a note that they will no longer produce etch resist inks.  The material is limited to the available supply - but all their inks appear to be available at this time.
