The only experience I had with Newton rings is with the Kodak 21
steps tablet and Agfa P911p Panchromatic Litho film. In my Condit contact
frame with normal glass I used to see Newton rings on the developped litho
film. I then switched to Coated glass and never saw them again... I can't
guarantee it is going to work for you and coated glass is expensive, but it
is the best glass you can get.
