Resolution Considerations for Graphics, Images, and Photographs 117
Using Scanners
For the best image quality, make as many adjustments as possible in
the scanner imaging software before scanning. These adjustments,
many of which are listed below, can increase the resolution of the
image, resulting in higher quality images:
z
Select the appropriate image type (for example, color
photograph, line art, or text).
z
Select the optimum image resolution based on image type, at
least 300 dpi for most images; however, select 600 dpi for line art,
graphics, and text.
z
Crop the image to scan only what you need. Scale the image for
the optimum resolution when it is reproduced.
z
Adjust the image sharpness, contrast, and brightness.
z
Set the gamma correction to 2.2. For more information on
scanner gamma correction, see the scanner's documentation.
z
When possible, import images at the size you plan to use (actual
size).
