This function detects blank pages (pages without any discernible content) and marks them for deletion. Pages marked for deletion will not be exported.

  

Threshold monochrome, Threshold gray, Threshold color

Specifies the threshold for blank page detection, for each of the image categories above. Enter the threshhold value as a percentage (a synthetic value based on the contrast between a page's content and its "optical background noise". The underlying algorithm ensures that even coloured or smudged pages are accurately identified as empty pages.)

New document

If this option is set to on (checkbox ticked), CROSSCAP Enterprise will insert a document separator whenever a blank page is detected.

Delete blank page

If this option is activated (checkbox ticked), then any blank pages found will be immediately removed (as opposed to being marked for later deletion).

Please note: If blank pages are removed using the "Delete blank page" option above, they will no longer appear in any of the CROSSCAP Enterprise statistics. If this causes issues with billing based on CROSSCAP Enterprise statistics, do not use this option (remove checkmark)!

Switched on

Switches this module on or off. Ticking the checkbox will turn this function on. Removing the checkmark will turn this function off but will preserve all settings, for later use / manual activation.

Image processing on server

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

If this option is activated (checkbox ticked), then the 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 Getting started, section Workflow CROSSCAP Enterprise).

Please note: If any errors occur during image processing on the CROSSCAP Enterprise server, manual indexing (on the CROSSCAP Multi-Client) will be enforced (even if manual indexing was not specified in the project template).

Whenever image processing functions are transferred to the CROSSCAP Enterprise server, we generally recommend to specify separate quality checks and/or manual indexing, since there is no other chance to inspect (and possibly rectify) images processed by the server, prior to finalization.

Also, please take care to treat all interdependent image processing functions the same way, i.e. either run all of them on the CROSSCAP Enterprise server or have all of them processed by the CROSSCAP Scan-Client.

Processing on page

Limits this function to certain pages. Possible choices are:

• Both pages
• Front page
• Rear page

Ignore monochrome pages, Ignore gray scale pages, Ignore color pages

Specifically applies to multistream mode. If any of these three filters are set to on (checkbox ticked), then this function is turned off for the respective page types. Please note that combining all three options Ignore monochrome pages, Ignore gray scale pages and Ignore color pages will effectively turn off execution all together, since there are no images left to process.
