PDF Watermark

Choose wording with a purpose

A watermark should communicate a clear status or ownership signal. Short labels remain readable over diagrams and paragraphs; long sentences can obscure the document and become difficult to interpret.

Use DRAFT for working copies, CONFIDENTIAL for controlled circulation, or a project label when recipients need to identify the document family. Avoid relying on a watermark as the only access control.

Balance visibility and legibility

Opacity should be high enough that the label survives printing but low enough that the underlying text remains usable. Test a page with dense text and a page with images before distributing the result.

Font size and placement affect both accessibility and review. A watermark crossing signatures, form fields, or technical dimensions may make the copy unsuitable for its purpose.

Watermarks are not security controls

A visible watermark can discourage casual redistribution and identify a copy, but it does not prevent screenshots, copying, or removal by a determined editor.

For sensitive material, combine labeling with appropriate access permissions, recipient controls, and an approved document-handling policy.
