If your DTP document contains watermarks on every page where can you place them?

In a DTP (Desktop Publishing) document, watermarks can be placed in the background of each page, either as a full-page image or text that is semi-transparent. They are typically positioned centrally or diagonally across the page to ensure visibility without interfering with the main content. Additionally, watermarks can be placed in the header or footer areas, depending on the design and purpose of the document.
