Customizing the Scanning Settings
3 Make the appropriate settings for the image to be scanned.
Image Type
Select a mode according to the image to be scanned. You can select
Color, Grayscale, Black & White, or Black & White (Text Enhanced).
Resolution
Select a resolution according to the image to be scanned. The higher the
resolution, the finer the image you can get, although the amount of data
will be large. In general, 90 dpi is sufficient for home pages, while 180 dpi
is good for output to a printer. Settings are 90, 180, 200, 300, 360.
Threshold
This function is valid only when Image Type is set to Black & White. The
lightness/darkness of monochrome images can be adjusted by moving the
slide bar. If the slide bar is moved to the left, the scanned image will be
lighter, while if the slide bar is moved to the right, the image will be darker.
Prescan
Place a check mark in the Prescan check box to perform the prescan. The
scanning mode can be set to Black & White, Grayscale, or Color.
Color Matching
This function is effective only when Image Type is set to Color. When this
function is enabled, the colors are adjusted according to the monitor when
the image is scanned. The monitor itself is set with the system feature of
ColorSync

in the Apple menu control panel.
