Color Dropout; Perform Color Correction - Xerox DocuMate 5445 User Manual

Color Dropout

Color dropout tells the scanner and software to remove a specific color from the image. You can choose either Red,
Green, or Blue, or define a custom color, to be dropped out of an image.
To input a custom color using its RGB value, select Custom in this list and then input the values for R, G, and B in
their appropriate boxes, where R, G, and B are numbers from 0 to 255.
Tolerance—use the slider to adjust the precision of the color dropout.
• More precise—this option removes a range of colors closest to the pure color selected or defined in the
custom fields. For example, pure red has an R/G/B value of 255/0/0. Selecting Red indicates that the scanner
should look for a range of RGB reds close to pure red and remove them from the image.
• More approximate—this option removes a wider range of colors based on the pure color selected in the list or
defined in the custom fields.
This option is only available when scanning in grayscale or black and white. The example below shows the original
text with a red watermark and the resulting image with the color removed.

Perform Color Correction

Apply color correction to the image so the displayed colors approximate the original item colors. Select this option to
use the scanner's default Gamma table which has been calibrated to produce the best quality color results for your
scanner. When this option is not selected, the resulting scans will be dark and the brightness, contrast, and gamma
options will require a greater amount of adjustment to affect the overall lightness of the image.
Automatic Color Detection Options
Select Automatic in the document source configuration list to enable these options. When you have selected the
automatic color mode, you will also need to choose either Gray or Black & White.
• Ignore document color—select this option to have the scanner ignore the color of the document when
determining if the scan should be saved as a color image.
• Color percentage—input the percentage of color pixels the scanner should look for to detect and save a color
image. The scanner determines color versus black-and-white by comparing the amount of color to the amount
of black in the image. The higher the value you set in this field, the more color is needed in the original item to
detect and save it as a color image. You can set the color percentage level up to 50%. This means that only
those documents which have more than 50% of the content in color will be saved as a color image.
