Changing the Scan As
option
Scan As
— three input options are available:
Color, Grayscale,
and
Black and White
.
• If you choose
Black and White
, the Black and White screen will be
displayed allowing you to choose either
Best (iThresholding)
or
Normal (ATP)
.
•
Best (iThresholding)
— selecting iThresholding allows the Scan
Station to dynamically evaluate 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 using iThresholding, you can only adjust Contrast.
•
Normal (ATP)
— 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 using ATP, you can adjust both Threshold and Contrast.
