|---|---|---|---|
| DRAFT / PRELIMINARY | 45° Diagonal | 15% – 25% | Centered across page; clearly flags review state without hiding body text |
| CONFIDENTIAL / STRICT PRIVACY | 45° Diagonal | 20% – 30% | Bold lettering in slate gray or red to deter unauthorized redistribution |
| Corporate Logo / Brand Emblem | 0° Horizontal | 35% – 50% | Bottom-right or top-right margin; reinforces document authenticity |
| Sample / Proof of Work | 45° Diagonal | 30% – 40% | Covers central graphics to protect creative output before final approval |
