This function will selectively convert color images into black & white or grayscale images, if no discernible color content is found.

Color detection searches for differences in RGB (red, greeen, blue) values, across each image. If RGB values for all pixels in an image are equal for each pixel, then this image has no discernible color content and is converted into into a black & white or grayscale image. If RGB values are substantially different, then the image is left untouched (and kept as a color image).

Filter:

Processing on page

Perform this function on ...       

• Both sides
• Front pages
• Rear pages

 

Ignore blank pages

Turns this function off, for all blank pages.

Ignore first document page

Causes this function to skip the first page of every document (which usually is the page triggering document separation). 

 

Ignore cover pages

Turns this function off, for cover pages.

 

Output:

Color conversion format

Select the target color-depth:

• Monochrome 1 Bit - recommended for plain text or text with line graphics
• Grayscale 8 Bit - recommended for graphical content with color gradients

 

Threshold

Increase the threshold to make this function more tolerant to differences in RGB values. 

In other words, increasing this value will make color detection less sensitive.

 

Switched on

Switches this module on or off. Turning this function off will preserve all settings, for later use (as opposed to removing the function). Useful when developing or troubleshooting project templates.

 

Image processing on server (CROSSCAP Enterprise only)

Image processing requires substantial amounts of CPU capacity. In order to relieve CROSSCAP Scan-Clients from this task and speed up all other processing, image processing functions may be selectively transferred to the CROSSCAP Enterprise server.

If this option is activated (On), then execution of this function will be deferred and processed by the CROSSCAP Enterprise server, later on. Deferred image processing will occur during the pre-process workflow step (see chapter Enterprise Server, section System workflow Enterprise).

 

(* This image processing function is also available during export. Use if one or more export formats need to be modified selectively.)
