I am new to screen printing so take it easy on me if this is a dumb question. Also, after searching the forum for a few I did not run across this question.
Right now I have a 16"x20" Ryonet UV screen exposure unit along with 20"x24" - 156 mesh screens.
For a printer I have the Epson 1430 with Rite Film WP Positives, but I do not have any RIP software.
When I exposed the screens, the emulsion was really hard to spray off (emulsion that was behind the print-out). I'm not sure
if that means I exposed to long or perhaps my ink is not dark/opaque enough.
Any information would be appreciated.

Do you have a stouffer strip/exposure calculator?

Yes I do have a strip. I think that I messed up the results by spraying to much water, I'm not really sure how that part of the procedure actually goes.

Go down to the fourth or fifth post in this thread. I posted some links that may help.

Frog, thank you for the links. I am checking them out now.

Looks like the issue was with my prints. After changing some settings in Illustrator I got really nice dark prints and the problem went away.
I suppose that means the print wasn't opaque enough and the UV lite was burning through the print and curing the emulsion.

That'll certainly do it. Up to a point, that's pretty easy to check by holding your positive up to a light source and checking.
