To avoid Newton Rings you have to avoid contact between the surfaces. One way would be to increase the space between the film and the glass. Of course, this is a bit of a catch 22 since the reason for using a glass carrier is usually to flatten the film between the glass layers.
There is a powder made for this purpose which is applied very sparingly which serves as a "buffer" between the glass and the film surface. Lastly, there is anti-newton coated or etched glass. Those are the ones I know of. Art Bill Grimwood wrote: > I am getting Newton rings in my scanning with my Minolta Dimage scanner.
