I recently acquired a lovely Focomat Ic enlarger. Everything works beautifully but there is one major problem: Newton rings. No matter how well I clean the condenser lens and negative, they are still there.
Now, I understand there is a special pressure plate named "NEWOO" (from the manual) specifically to eliminate Netwon rings, but that may be very difficult to find. I also tried to place the anti-newton glass from my Meopta enlarger between the Focomat's condenser and the negative, but it doesn't fit because it's too thick. I'm not sure whether I could get a thinner AN glass from somewhere.
I wonder how other Focomat Ic users have solved this problem.
Thanks a lot,
