Michael, I use the non-glare glass from Tru Vue in my contact frame specifically to eliminate Newton's rings and have not seen any texture or gincreased graininess in my prints. I also use it in my 8x10 negative carrier for the top glass, and plain Tru Vue glass on the bottom with Kodak Portra negatives without rings on the underside. I considered getting their museum glass since it is supposed to be colorless, but I haven't seen the need in my color prints to spend the extra money.
