Try unfiltered uv blacklight. Comes in flourescent tubes. Floodlight won't do it.

Forgive me, but I have to ask.

You did dry it away from light sources, right?

You will most likely have to order the tubes
from an electrical supply. It's not something
Home Depot would have laying around.

BTW. Don't look at the lamps without
eye protection. It's pure UV,
(or close enough to it) and can damage your
eys just like staring at the sun.

You could also try the sun! If your just starting out and don't want to build anything crazy or spend a ton of money, you could use the sun to expose your screens. There is no better source for uv light rays. They are the straightest and strongest rays available. Even on an overcast day it should only take 35-80 seconds!

Good-luck!

Depends on what emulsion you use and the time of year. In the summer in Florida, RLX takes 3 minutes in sunlight. A little longer in winter. Different emulsions expose at different rates.

Good point. The best thing to do would probably be to run some test. The more scientifically you do the tests....the better.
