Rubber stamp letterforms with authentic ink impression quality. Heavy, dense ink — slightly over-inked at stroke edges creating characteristic bleed and fill. Worn letter edges from repeated use, slight ink fill inconsistency within letterforms. Bold, compressed letterform proportions typical of official stamp typefaces. Dark red-black or pure black ink. The physical authority of metal type pressed into official paper. Not typewriter finesse — stamp permanence and weight. Clean white official document paper, crisp and institutional. Neutral overhead lighting, government document aesthetic. "CERTIFIED" perfectly centered, filling 62% of frame width. Ink applied with heavy, deliberate pressure — strokes dense and authoritative, slight bleed at edges suggesting rubber stamp impression. Letter edges slightly worn as if the stamp has been used hundreds of times. Generous negative space around the word — the emptiness amplifies the authority. No other text. No decoration. The word is the document.
