Black And White Adjustment Option - Kodak Scan Station 700 series User Setup Manual

Black and White
Adjustment option
A-61808 September 2014
Black and White Adjustment — allows you to change the Contrast
and Threshold values. This option is only available if your Scan As
selection is Black and White.
• If you select Best (iThresholding) on the Scan As screen, only the
Contrast value can be changed.
• If you select Normal (ATP), both Contrast and Threshold can be
changed.
Contrast ⎯ adjusts the amount of the image foreground which is kept
or attenuated. Decreasing this setting will reduce the amount of noise at
the expense of possibly losing faint text. Increasing this setting will help
make faint text more visible at the expense of creating more noise.
Threshold — converts a grayscale image to a black and white image.
The thresholding values range from 0 to 255. The default is 90. A low
threshold value produces a lighter image, and can be used to subdue
backgrounds and subtle, unneeded information. A high threshold value
produces a darker image, and can be used to help pick up faint images.
1. When you select Contrast or Threshold, the Contrast (or
Threshold) screen will be displayed.
2. Use the Left and Right arrows to adjust the value, then click Done
to save the value.
