Steve,
I am not sure if you have an iGen3 or iGen4 system with FreeFlow Print Server.
On the iGen3/FFPS system, assuming you do not have the ACQS software suite that is provided by Xerox Special Information Systems (XSIS), the Pantone CMYK Tables are static. These tables are simply text files that reside on the hard drive of the FFPS System. If you are familiar with navigating on a Solaris system, they can be found in the /var/spool/XRXnps/resources/color/tables directory on the sytem. There are both CMYK and Lab tables for coated, uncoated and GOEcoated Pantone colors. Whatever you do, you should not try to alter or remove the tables from this location. However, you can copy them out and format them in a way that would be suitable to provide to your customers.
On the iGen4/FFPS system, the tables are located in the same location, but are not static. When profiling on the FFPS system the user is given the choice to update the Spot color tables if so desired. If they chose to update them, then these files are modified with new CMYK values based on the scan results from the profiling process. If you update your destination profiles from the Color Maintenance Tool (CMT) on the Press Interface, then you are not given an option and the spot color tables are updated. However, at any time you can revert to the default CMYK Spot color values by opening the Spot Color List in the FFPS GUI. If the values have been updated by the profiling process, then a "Revert" button will appear at the bottom of the Spot Color List window.
If you have any other questions, or require clarification of any information provided, please feel free to contact the iGen Customer Support Hotline at 1-800-821-2797.
