Image Settings -
Adjustments tab

The options available on the Adjustments tab depend on the

Scan as

selection on the General tab. The following options are based on a

Scan as

selection of

Black and White

.

Conversion quality

— these settings effect how the scanner analyzes

a grayscale version of the document which is used to produce the black
and white electronic image.

•

Best

(iThresholding): the scanner analyzes each document to

determine the optimal settings to produce the highest quality image.
This option allows scanning of mixed documents with varying quality
(i.e., faint text, shaded backgrounds, color backgrounds) and when
scanning with consistent document sets.

•

Normal (ATP)

: allows you to determine the optimal settings to

produce the desired image quality. This option works best when
scanning with consistent document sets. You may also want to use
this option if you have difficult documents such that you cannot find a

Contrast

setting for

Best

that produces the desired quality.

•

Draft (Fixed)

: allows you to select the grayscale threshold used to

determine if a pixel is black or white. This option works best for high
contrast documents.

Contrast

— allows you to make an image sharper or softer. Decreasing

this setting will make the image softer and reduce noise in the image.
Increasing this setting will make the image clearer and make light
information more visible. The options range from-50 to 50. The default
is 0.

NOTE: This is only available for

Conversion quality: Best

and

Conversion quality: Normal.
