ESOLUTION
Resolution determines how many pixels, or dots,
are used for scanning and reproducing an image.
As the resolution value increases, the scanner
reads and reproduces the image in finer detail.
You might hear resolution described in terms of
dots per inch (dpi), or pixels per inch (ppi).
The best resolution setting really depends on the
type of image you are scanning and the printing
method. The table below shows optimum
scanning resolutions for most needs.

Remember that the higher the resolution, the
larger the resulting image file. An 8 l/2 x 11-inch
color photo scanned at 300 dpi requires 25MB!
Larger files use up your computer and hard disk
memory; they take longer to process, to print, or
to transmit by modem; and they are more difficult
to save to a disk for sending to a service bureau or
printing company. Selecting the lowest possible
resolution that gives acceptable quality keeps file
sizes manageable.
