I finally got around to finishing mine up. It was kind of a pain. First I used a test piece and it didn't expose very well---the text wasn't dark enough (even though I was using transparencies) Here's a hint--if you're using transparencies set your printer on normal paper anyway. My laser printer printed tranparencies lighter on the transp. setting then simply running it through on the paper setting.
Anyway then I went to run the 2 panels. I exposed it and soaked it for the 15 minutes like it said you should. At the end of that I took the screens out of the water and ALL of the coating washed away. (that's bad)
I think I might have put the screen upside down.
The next few days were semi-cloudy and I didn't want to risk is since I had already wasted 1 sheet.
Today I decided to go for it and I realized I needed to change the font on everything because the newer test patch didn't work any better. I changed it then I also copied and duplicated the image slightly off center to make it more bold. It seemed to help a lot.
I exposed it and everything seemed to work reasonably well, I figured I was getting somewhere. I used liquitex paints and taped the screen to the panel. It said to use a brush for hi-res..The first time I tried to paint it I didn't it lightly, and when I went to peel off the corner, parts weren't coming through. Then I slowly taped it back down and gradually repainted it. No matter what I did some parts came up without having paint travel through the screen, others smeared and got unclear.
The panel looks ok--I'll post some pictures in a little while, but all in all it was a big headache, somewhat expensive and not very impressive looking. I'm going to give it another shot but unless you have big bold text, even with the hi-res stuff it's not that easy to do.
