Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
Success on press notwithstanding, I am now interested in quantitative readings of comparative EOM with all things other than light source being equal.

I think (know from experience) that you can underexpose photopolymers to retain detail, baby it throughdeveloping, and post expose in the sun and get a pretty well usable screen. Not ideal in the slightest but probablypretty common practice.With diazo we expose for an inordinate amount of time, retain excellent detail, blast with reclaim pressure washerto develop, and don't post expose. We then beat the brakes off our stencils on press, we're about to print across 600 zipswith discharge. I got 99 problems but a properly exposed screen ain't one.It would be cool if people mentioned what emulsion(s) they're using as that's the make or break with LED.
Alan,does your screen loop allow you to expose, soak, rinse, place in drying rack and tape up two more screens in less time than the draw down of the exposure... if not I am not seeing the issues. I have the same unit as you and was disappointed at first with he 45 second draw down but soon realized it was of little significance in real time screen making for my shop.
We use Diazo, never tried anything else on our LED. Never had a reason to yet I guess.
