      Label PDF pages with visible text such as a draft or review marker. Set the watermark text and appearance, then check that the exported document remains readable. A visible watermark identifies the copy but does not prevent copying.

      The text setting adds a watermark to every page. For a positioned logo or text, add edits in the preview. Visible watermarks are not copy protection.
