im pretty sure the starlight is on par with our back panel on the STE. We typically expose big blocky images between 6-8 seconds. Really fine halftones (65lpi) we are usually using our front LED bar, but we've also had some success doing it for 1 second.

All screens coated 1/1.

I just looked at the first test and a 180/48 coated 2/1 thin/sharp edge resolves 7 solid steps on a Stouffer greyscale in about 20s.   Keep in mind this is with glass in the unit and film, not CTS style.

There must be something different in the PHU to a typical photopolymer though since it has such high reported water resistance.
