Removal of crop marks

To automatically remove crop marks, the document must:

  • Have a CropBox on each page.
    • The CropBoxes must be identical on each page.
  • Have a TrimBox on each page.
    • The Trimboxes must be smaller than the Cropbox and contained in it.
    • The TrimBoxes must be identical on each page.

Presence of a BleedBox is optional.

Valid page for the removal of crop marks

The page will be cropped to the TrimBox, and as a consequence, nothing outside of the TrimBox will be kept.

To add crop marks, the document must :

  • Either have no visible crop mark, in which case the entire original page will become the TrimBox of the printable document.
  • Or be valid for the removal of crop marks.
