There is such a facility in the form of a specially altered profile we call an "Ink Alarm" profile (we have a patent pending on the process).
We can create these profiles from any proofing profile (from a customer's press, for instance) that is supplied to us by the customer.
Basically, the customer specifies to us a) what the ink limit threshold is for their system (say, 320%) and b) which color they want the "alarm" to be.
We then alter their profile so any inking levels over the threshold proof to the alarm color. This is an effective system as the profile is useable as a normal proofing profile either for soft/hard proofing in Photoshop or hard proofing in a RIP proofing system. As long as the files are separated with less than the threshold value they will proof normally. When files (raster OR vector) that contain over-inking are sent through the profile, the over-inked areas turn bright pink (red, blue, green, whatever). It is quite obvious on proof what the problem is and whether editing or reseparation is required.
please contact Rick Hatmaker at sales (at) chromix.com if you have any questions about the service.

Steve
