Scanning Tips
Getting the best scan possible depends on several factors, including the quality of your
original and the resolution you select. The better your original is, the better your scan
will be. To get the best possible scan, keep the document table clean, and make sure
the document is flat against the glass surface. You can make many corrections in your
scanning software. For additional photo retouching, use an image editing program
such as Adobe Photoshop Elements.
Selecting Resolution
Resolution refers to how many dots per inch (dpi) or dots per centimeter (dpcm) your
image contains. The best resolution for a scanned image depends on the type of image
you’re scanning and your final output device.
If you want to print the image in its original size (1:1 ratio), scan it at 300 dpi. To
enlarge photographs or scan documents for your OCR software application, select a
resolution of 400 to 600 dpi. If you’re scanning an image to view on-screen,
choose 96 dpi.
