You must introduce a slight distance between the negative and the
negative clear glass. This can be done with a piece of masking tape
placed on the edge of the clear glass negative carrier out of the
image area. Or use an anti newton ring carrier which introduces the
distance by itself. Are you using a Durst enlarger...an old one
would have this problem?

I'm confused. Isn't the purpose of glass to hold the neg flat and in
the focal plane?
We failed to ask Elias whether the rings are linked to the components
of the image or are closer to the size of the negative.
I was assuming they were related to the image structure. Perhaps
this is not the case. If the rings are not around image elements my
comments may not be applicable.
