Re: Polymer Plate 80% screen Weirdness

Hi Jan,

Prior to firing up the frame vacuum I was using a contact frame which was having
the same effect, only worse. The newton rings were much larger! I've gone this
far, I might just as well try the talc in the contact frame as well as the frame
vacuum and see what happens.

So baby powder (as opposed to pure talcum) is not a problem?
