Scan As option
Scan As
— available selections:
Color, Grayscale,
and
Black and
White
.
If you select
Black and White
, the Black and White screen will be
displayed. Select either
Best (iThresholding)
or
Normal (ATP)
.
•
Best (iThresholding)
— the Scan Station dynamically evaluates
each document to determine the optimal threshold value to produce
the highest quality image. This allows scanning of mixed document
sets with varying quality (such as faint text, shaded backgrounds, or
color backgrounds) to be scanned using a single setting thus
reducing the need for document sorting.
When
Best
is selected,
only
Contrast
can be adjusted on the Black and White Adjustments
screen.
•
Normal (ATP)
(Adaptive Threshold Processing) — separates the
foreground information in an image (e.g., text, graphics, lines, etc.)
from the background information (e.g., white or non-white paper
background). When
Normal
is selected, you can adjust both
Threshold
and
Contrast
on the Black and White Adjustments
screen.
