FreeFlow Core has a "Color Split" capability. Here is a description from HELP of the capabilities and below a screensnap of the controls:
The Color Split component separates jobs into color and monochrome jobs that can be reassembled either manually or at the printer. The Color Split component generates a Job Group with a monochrome and a color job.
•Color Insert Handling: Defines how to adjust the monochrome print ticket based on the expected assembly of the mono and color jobs.
•Merge In Printer: To enable insertion of split color pages at the printer, the monochrome job ticket is adjusted.
•Merge Manually: To enable manual insertion of split color pages, the monochrome job ticket is adjusted. Each contiguous set of color pages is replaced with a single-sheet insert in the monochrome job.
Color Insert Stock
Defines the Stock Name to use for the sheet inserts that represent the color pages that were removed from the job.
Append “Color Inserts” to Job Name
Defines how a file is renamed for the Color Insert job.
•Check Color Coverage: Determines whether to evaluate color coverage when you determine whether a page is color or monochrome. If you do not select the check box for Check Color Coverage, A page with any color pixels is specified as a color page.
•Minimum Color Coverage: Defines how the color content coverage threshold is used to determine if a page can be added to the color job.
Note:Coverage is rounded upward. When the Minimum Color Coverage is set to 1%, pages with any color content are added to the color job. Setting the Minimum Color Coverage to 1% is significantly faster than other selections.
•PDF Box: Constrains the Minimum Color Coverage evaluation to the selected PDF Box when the Minimum Coverage Threshold is above 1%.
•Use Job Ticket Settings: Determines whether to evaluate the job print ticket when you determine which PDF pages are assumed to be on the same sheet. If monochrome PDF pages are considered to be on the same sheet as a color page, they are added to the color job.
•Sides Imaged: Defines whether the print is 1-sided or 2-sided when you determine which PDF pages are on the same sheet.
Note:The Sides Imaged setting overrides the setting for 1-sided or 2-sided printing as defined in the job ticket, unless the job ticket is set to use the Sides Imaged Job Property.
