Incorrect White Overprint Objects Generated in PDF Marks

For many years Illustrator has been generating white objects with overprint enabled inside printer marks, registration marks, or trim mark areas during PDF export.

These objects are invisible in print but trigger preflight and RIP warnings in professional workflows.

This issue has existed across multiple Illustrator generations and still appears in exported PDFs.

White overprint objects should never be generated in PDF output unless explicitly created by the user.

Please investigate and eliminate these unintended overprint elements from exported PDFs.
