Polymer Plate 80% screen Weirdness

Hi All,

I'm starting to get set up at home to burn photopolymer plates with my
blacklight box built from Dick Sullivan's fabulous directions in his book
on PT/PD printing.

What I'm finding is the 80% density, 300lpi screen I'm using to
pre-expose the plate is resulting in a kind of mottling effect. Looks
like water spots directly on the plate.

Has anyone else come across this?

Thanks,
Jon
