Example attached.
Can you see the Newton Rings already on the photographic print or is it at first on the scanned result ? In that case it could possibly be Newton Rings from the contact between the print and the scanner glass. I know it sounds improbable as the print surface seldom is flat enough unless you ferrotype the print or use glossy RC-paper. It can be worth looking into.
