The preflight in FFCore can be used to determine whether PDF trim and bleed boxes have been defined as expected for a document that should contain bleeds.
You can check whether the trim and bleed boxes are the same size. You can also check for a minimum distance between the trim and bleed box. If these checks fail preflight in FFCore, the Preflight Result will be set to completed with warnings. You can route jobs with that preflight status to automatically sort jobs that should have bleed (per order information) but do not (per PDF trim and bleed boxes).
