By changing the resolution of the scanned image from the default setting of 200 dpi to 75 dpi, the file size becomes smaller and takes less time to download. When viewing the scanned image on a computer screen, no difference in image quality is evident between a 200 dpi image and a 75 dpi image. This setting selects the output resolution for the scan. Available resolution options are: 50, 75, 100, 150, 200, 300, 400, 600, 800, 1200, 1600. The following values can be input directly: 25 to 3200 (in 1 dpi increments), 6400, 9600, or 19200. Determine the best scan resolution setting. You can specify the desired scanning resolution within One way you can test the effect of increased scanning resolution: 1. Make a series of scans at various resolutions. 2. Now, using a package such as ImageMagick or NetPBM, do some processing: a. Try expanding the 300 dpi image to 600 dpi using appropriate intermpolaton (usually bi-cubic) b. Now, subtract one image from the other. that uses the full resolution of the scanner’s CCD, even scanning at a lesser resolution. The benefi t of this feature is truer image quality. For example, on one of the Epson 600 dpi Perfection scanners, when scanning an image at 300 dpi, the scanner still uses all 600 pixels per inch to scan the image, then This scanner is recommended for 4000 pages per day.
