Pierre is on CCI Nexus emulsion now. If you have run PHU 2, the data numbers are almost identical. 48% solids. It's great for plastisol, wb, d/c. Long runs or D/C you can add diazo. Nothing really changed with exposure as far as I know. It did however shore up pin holes that were becoming a problem with some emulsions.
CCI LXP is optimized for LED. You can get 4-5 sec exposure on an I Image STE and most LED units.
