DETERMINING YOUR RESOLUTION
Proper control of the resolution obtains satisfactory detail of
scanned images. Resolution is measured by dots per inch
(dpi). Normally, the higher the resolution the larger the
image file size will be, but at higher quality.
Greater resolution requires more time, memory and disk space. There
is a limit beyond which the resolution will not produce much visual
improvement, but will make your files more unmanageable.
Resolution: Left = 50 dpi Right = 100 dpi
An A4 size color image scanned at 300 dpi at True Color mode
consumes approximately 25 MB of disk space. A higher resolution is
recommended only for a small area at True Color mode.
The following table offers a suggestion to help you choose an
appropriate resolution.
