[. . . ] The same original scanned at 72 dpi creates only a 1. 3MB file. Large files take longer to process and print, so consider the practical limitations of your computer system when selecting a resolution. To keep your file size manageable, select the lowest possible resolution that gives acceptable quality. When scanning at a higher resolution, reduce the file size by scanning only part of the image. s Scaling (Resizing) Images If you plan to enlarge your image, it is better to enlarge it when you're scanning rather than in your application. Each time you modify an image, you lose some quality. Keep in mind when you enlarge a small photo, such as a 35 mm slide or wallet-size photo, you'll need to scan at a high enough resolution to retain your image quality, but not so high that your file size is too large to be efficient. You must manually adjust the resolution (dpi) to maintain the same image quality when you resize your image. For example, if you have a 300 dpi 2 × 2-inch image that you want to enlarge to 4 × 4 (a factor of 200%), increase the Scale setting to 200% and change the resolution to 600 dpi. 44 Advanced Scanning with EPSON TWAIN Transparency Unit This section includes basic information on unpacking, installing, and using the transparency unit (B813172).
