I use the following filters in the order listed to improve my scans of Matte Images:Noise Dust & Scratches: Radius: 3, Pixels, Threshold: 12 Pixels Reduce noise: Strength: 8, Preserve Details: 60%, Reduce Color Noise: 45%Median Filter Radius: 3 PixelsMedian Filter Radius: 3 PixelsGaussian Blur Radius: 2 PixelsFortunately, most of the photos were taken with a low quality camera, and I scan them at 1200 Pixels/in. Consequently, while these settings blur the image slightly, the overall image quality is much better. In the attached image, the right end is 'as scanned' from the 'white' edge of a photograph. The two grayscale images were created by using the : Enhance-->Auto levels. The filter sequence above was applied to generate the center panel. These were then converted to black and white to exaggerate and emphasize the Matte matrix. InI fully believe that due to the periodic nature of the matte finishes, a matte removal filter could be designed. Note: This is only one of several matte patterns that I have seen.
