System for visualization of conformal contact. The system visualizes conformal contact between a patterned stamp and a transparent impression surface. A patterned stamp is provided that includes a fluorescent structure for contact with the impression surface. A source of UV light is provided for transmission through the transparent impression surface to interact with the fluorescent structure to generate visible light re-emitted by the fluorescent structure. An imaging system captures the visible light to form a high-contrast image of an area of conformal contact between the patterned stamp and the impression surface. The high-contrast image comprises bright and dark regions representing contact and no contact respectively.
