Homebrew PCBs

I don't do screen print. I do know a little bit about it, though,
probably enough to be dangerous. ;')

Why would you print onto the screen? A screen has to be exposed just
like photosensitive PCBs so you print a transparency then expose and
develop the screen.

It's been discussed here quite a bit, that fabric printing screens are
just not fine enough mesh to screenprint etch resist.

If you mean can the screenprint inks be fed into an inkjet printer,
no, they are way too thick.

I am going to try the pigmented inks I use directly onto a PCB. I am
assuming I'll have problems with puddling, so I'm going to start out
with a hot board and lay down very little ink for a start. I have some
thin PCB about the thickness of a business card, that should feed fine
in my printer.
