Checks if the PDF's trapped flag is set to a specific status.
The trapped flag in a PDF document indicates whether
the document has been "trapped", i.e. corrected for slight color misregistrations, or not. The
trapped flag must be defined in PDF/X documents.
The flag can be set to:
- True: The document has been trapped, or the document creator has
decided that it should not be trapped.
- False: The document has not been trapped.
- Unknown: The document status is not certain.
Note: The status Unknown leaves room for errors in the workflow and
should be avoided, especially if you cannot contact the document creator for details on PDF
document’s trapping.
Note
that you can also check if the trapnet annotation conforms to the PDF/X standard, by selecting
the corresponding check in the PDF Standards category. See
Trapnet annotation (PDF/X).
Possible fixes
You can immediately change the trapped flag as required.
