Hi,
I use a flatbed scanner to scan oil paintings so that I can make prints. This involves scanning the painting in small sections and then stitching the whole thing together with photoshop.
I first bought a Epson photo perfection V100 which is sort of ok image wise but then tried the latest version of scanner; the Epson perfection V37 which produced sharper brighter better coloured images.
All appeared well until I scanned a painting with even pale blue sky and then found banding in the scanning direction on the images. Dissasembly and inspection of the scanner shows the light source to be a row of LEDs which could be producing uneven illumination but does not quite match the pattern on the scanned image. The V100 has a tube light and gives even illumination. The problem only shows up in pale smooth images.
Any ideas on how to improve the v37 images?
PS not sure if this belongs in the general hardware forum
