  It is my favorite because it reclaims easily even if under exposed. If your emulsion is giving you problems in the reclaim room you might want to find one that does not.

Or you may want to try exposing it properly.
Theirs no excuse for underexposure as it leads to an assortment of problems, one of them being difficult reclaim.

He didn't say he was purposely underexposing he said in case of under exposure. But I am sure you knew that.

Emulsion is ChromaBlue pure photopolymer and exposure unit is Nuarc 40-1K Mercury bulb 1000w.
It takes about 2 minutes per screen (I have never measured the time, it has light integrator. It might be a bit more or less than 2 min). No issues with washing out, decent detail, 2 year shelf life, blue in color (do not like the look of pinkish emulsions).
I have a bit of the emulsion left and I will be switching to ImageMate PC 701, it is almost the same emulsion (per people at Chromaline, they make it) with a slight faster exposure times and a better price at my supplier.

I measured the time needed to expose 155W and 230Y screens last nigh. 155W was 90 seconds and 230Y was around a 100 with my 1000W Mercury exposure unit and Chromablue. That should be slightly improved when I switch to PC701. 230Y had a halftone design with 50 lines/inch and 22.5 angle and washed out with no issues (no dots dropping off)

No need for me to under expose because of poor dmax values, we have a cts unit.
