Additional page
properties for
color scanners
A-63054 February 2004
For the Color Scanner 3590C and Color Scanner 4500, the following additional
page properties are available:
Pixel precise—when the page setup is configured to do auto-rotation and/or
auto-cropping of color images without deskew, then this check box becomes
available. When enabled, Capture Software will perform pixel-precise auto-
rotation and/or auto-cropping. Enabling pixel-precise should result in the
complete removal of any black borders around the color image that may
remain if pixel precise were disabled.
NOTES: Auto-cropping and auto-rotation are more accurate with pixel-precise
enabled, but they are slower than when pixel-precise is disabled.
When one of the deskew options is enabled, pixel-precise is
automatically enabled, as color deskew processing always includes
pixel-precise auto-cropping.
Scanner Color sharpening—enable this check box to configure the scanner
to perform color sharpening as part of the scanning process. Color sharpening
improves the readability of small text (8-point type or smaller) on color
documents. By default, scanner color sharpening is enabled when color
deskew processing is disabled.
However, when color deskew processing is enabled, Scanner Color
sharpening is automatically disabled. With color deskew processing, color
sharpening needs to be performed by the software after deskew. As a result,
Scanner Color sharpening should be disabled and software sharpening should
be enabled.
Software sharpening—select No software sharpening, Low, Medium, or High
on the drop-down list. When enabled, color sharpening is performed by the
software after all other color image processing. When color deskew processing
is enabled, software sharpening is automatically enabled (and is highly
recommended). Medium is the default setting. When color deskew processing
is disabled, software sharpening is automatically disabled. The higher the
software sharpening setting, the better small characters will be able to be read
after color deskew processing. However, a higher setting will result in larger
color images sizes and slower color image and deskew processing.
