Back to emulsion, I have used Ulano RLX for years. With my Douthitt exposure unit,
if you can put it on film, I can put it on a screen. I have held 2% before and I have also
done runs of up to 30,000 solvent ink (lacquer) without a pinhole. I have also run 4CP
twice a year (3,000 per run) and have the same screens I made 6 years ago.
