A practical guide

Make the revision status explicit.

  1. Choose the project PDF and enter a revision or review label.
  2. Set an available placement and opacity for the chosen copy.
  3. Apply the mark and compare dense data and diagram pages for obstruction.

Try this example

Add REV 03 at low opacity to a six-page project report. Inspect a measurement table, a diagram and the final page before distribution.

Input and expected output for this task. Illustrative example.

Before you start: The watermark changes visible pages but does not remove metadata or hidden content and is not secure redaction.

Add page numbers
What you get

Add a text watermark to every PDF page. Choose diagonal, center or footer placement. Use Add Logo to PDF for PNG/JPG marks. A watermark does not remove underlying content.

Limits and important details

Text is applied to every page in diagonal, center or footer position. Latin, Greek, Cyrillic, Hebrew, Arabic, Chinese, Japanese and Korean text is supported. This is a visible label, not redaction, encryption or copy protection; existing digital signatures may be invalidated. Use Add Logo to PDF for image marks or Add Letterhead to PDF for a PDF template.

Example

Use the six-page sample and enter DRAFT. Choose diagonal placement and low opacity. Check that all six pages are marked and the original text remains readable.
