Hello, I posted this a few days ago but I think I may have poorly categorized the question, so I hope to try again in this forum. Using the Coolscan 8000 or 9000 with the FH-869G glass holder for scanning 120 film, I understand that there are anti-newton ring "masking sheets" that ship with the holder. What are the masking sheets made of? Are they simply a thin sheet of paper or plastic designed to prevent contact of the film with the upper glass, or is there more to it than that? How thick are they? I bought a used Coolscan 8000ED and the FH-869G glass medium format holder but I did not receive the anti-newton "masking sheets" that come with the unit when you buy it new. I know that I could probably order replacement masks from Nikon, but I was hoping that I could make them myself, saving time, money, hassle. Thank you kindly for your help. Jeff
Hi Jeff, The masks that came with my glass holder are matte black plastic and are as thick as 4 or 5 sheets of plain printer paper. If you have the blackouts for the 35mm holders it's the same material. Each different mask has a unique hole pattern on the end. I think the holes are codes to tell the scanner what format of film is(6x6,6x7 etc.). Will
