Selecting Resolution

  Resolution refers to how many dots per inch (dpi) your image contains.

  The best resolution for a scanned image depends on the type of image you're scanning and your
  final output device.

  For most images, use a scanning resolution that is approximately one third of your output
  resolution.

  For example, use a scanning resolution of 200 dpi if you want to print at 600 dpi.

  If you're scanning an image to view on-screen, choose a resolution of 96 dpi.
