Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
We are using a 3k Tri-Light. I did some screens yesterday with HXT, 3 over 1 coating on 125 mesh, shot them at 600 LU, for this unit that's roughly 6 mins I believe. Remember for us, no glass or film using the I-Image. 1200 piece discharge run, double strokes, and zero breakdown or signs of wear after the wash out of the screen.
Honestly my cci rep told me to go to 3/1 from the 2/1 we were doing. we were having an occasional pinhole issue. We went through making sure our screens were super clean, they were, he said try the 3/1. since then, no pin holes. It has low solids so I guess that may be a reason, not totally sure, but even with the 3/1 round edge, the stencil isn't nearly as thick as a 1/1 chromablue coated screen with the round edge. I have no idea how you are able to pull those times off with the photosharp 1k, but you can and that's awesome!!! I think we've had this chat before and you are in a very dry dry location right? We constantly battle humidity here, even with dehumidifiers, today is 80% in the shop.
Water filter sounds interesting man!!! Our water is pretty nasty in Polk county, sometimes we can see marks on the screen mesh from the water that ran down after standing the screens up to dry. Maybe there is some nasty crud in the water itself. Seeing how you could tell a noticable difference from trying to expose a screen coated in the same day vs drying over night prooves this stuff needs to be dry as a bone. I just checked my room where my screens store and even with the ac and dehumidifier running its still 55% today . Constant battle with humidity. I'm glad to hear the emulsion is working for you though, it is great when all is dialed in. I need to get ahold of an EOM meter to see where I am.

Horizontal= better
