About trapping

The trapped flag indicates whether or not a file has been "trapped", i.e. has been corrected for slight color misregistrations. The trapped flag must be defined in PDF/X documents.

The flag can be set to:

True: the document has been trapped, or the creator of the document has decided that it should not be trapped.
False: the document has not been trapped
Unknown: it's not known whether or not the document has been trapped. Note that this status should be avoided.

The trapped flag is stored in the info dictionary and/or in the XMP metadata stream, but the data can be inconsistent; that's why you must indicate where the trapped flag must be taken from, e.g. from the most recent metadata location.
