ink doesnt dry quick enough consequently it runs or smudges edges
I have done a board or two printing artwork to plain paper and
exposing for a minute or so in sunlight , worked well but now
use Laser printer and transparencies for development

If you're talking about the photographic process where a
sensitized board is exposed to light with the artwork on
a transparancy, then the inkjets typically don't get dark
enough for fine line work. Laser toner is much more opaque
than any of the inkjet inks I've seen so far.

Also there are methods that rely on the fusing of the toner to the board.
Ex. PNP Blue.




I tried printing the traces on a transparency with my inkjet and it turned
out almost perfect. There were no smudges or anything and it looks pretty
dark(it has a green hue to it though and I'm not sure if my printer is using
the black ink completely or not.) I'd say its 99% perfect as far as the
traces are concerned. There is a little "streak" about 1 mm long through one
of the traces but that is easily fixed. I will go ahead and try it and see
what happens. Hopefully the ink is thick enough to block the UV light. I
might post my results if they are decent.
