Watermark Settings
A watermark is a visible label. Use clear text, moderate opacity, and a position that does not cover important document content.
| Setting | What it controls | Practical tip |
|---|---|---|
| Opacity | How visible the watermark is | Use a lower value for background labels. |
| Angle | The rotation of the text | Diagonal text works well for draft labels. |
| Position | Where the watermark appears | Use corners when the center would cover content. |
Watermark Limits
A PDF watermark is helpful for labeling drafts, samples, and reference copies, but it is not security. It does not stop screenshots, copying, printing, or file sharing.
| Goal | Watermark helps? | Reminder |
|---|---|---|
| Mark a draft or sample | Yes | Use short text such as Draft or Sample. |
| Show ownership or source | Often | Use readable text and moderate opacity. |
| Prevent copying | No | Use document permissions or a secure sharing system. |
| Hide private content | No | Remove or redact private pages before sharing. |
