A watermark annotation (PDF 1.6) is used to represent graphics that are expected to be printed at a fixed size and position on a page, regardless of the dimensions of the printed page.
Watermark annotations have no pop-up window or other interactive elements. When displaying a watermark annotation on-screen, viewer applications should use the dimensions of the media box as the page size so that the scroll and zoom behavior is the same as for other annotations.
| Since many printing devices have nonprintable margins, it is recommended that such margins be taken into consideration when positioning watermark annotations near the edge of a page. |
