Selecting a Suitable 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 how you plan to use it. 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. Follow the guidelines in this table for selecting a resolution: Type of scan Photograph Text with images Film or slides Line art Image for web Text for OCR Newspaper Magazine Resolution 300 dpi 400 dpi 300 to 2400 dpi 300 to 2400 dpi 96 to 150 dpi 300 dpi 150 to 300 dpi 150 to 300 dpi Scaling (Resizing) Images If you plan to enlarge your image, it's better to enlarge it by scanning at a higher resolution. If you change the image resolution or size in an application, you lose image quality. Keep this in mind when scanning small photos that you plan to enlarge, or when scanning slides and negatives. 30 Getting the Most From Your Scanner
