Fail If Possible Output Inconsistencies
Apogee Preflight Action List
Agfa Apogee Prepress 7.0 and higher
What it does:
The Apogee Prepress action ap_Fail IfPossibleOutputInconsistenciesFound v7.0.1 checks if the document might be rendered differently by a non-Apogee renderer.
Some PDF constructs view differently than they are outputted and different versions of Acrobat don't necessarily behave the same. This Agfa Apogee Preflight action list will warn for such special PDF objects.
Additional information for Prepress experts:
