To estimate scan resolution

You can determine the resolution for your scan using the original and final image dimensions and the resolution of
your output device. Scan resolution translates into image resolution when you open the scanned image in Photoshop.
Do one of the following:
1
For laser printers and imagesetters, multiply the printer's screen frequency by 2. To determine your printer's screen
•
frequency, check your printer documentation or consult your service provider.
For inkjet printers, check your printer documentation for the optimal resolution. Many dye sublimation printers
•
and devices that print directly onto photographic paper have an optimal resolution of 300 to 400 dpi.
Determine the ratio of the final image dimensions to the original image dimensions. For example, the ratio of a
2
6-by-9-inch final image to a 2-by-3-inch original image is 3:1.
3 Multiply the result of step 1 by the result of step 2.
Uses the default settings.
Uses custom settings.
