• 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 (i.e., white or
non-white paper background). When Normal is selected, you
can adjust both Threshold and Contrast on the Black and
White Adjustments screen.
