Short definition
A projection surface is whatever a projector casts its image onto. It can be a classic screen, a coated wall, a curtain, a building facade, or any three-dimensional object.
Detailed explanation
In the broadest sense, almost any surface can serve as a projection surface — from a classic matte-white screen to a building facade in architectural mapping. In practice, requirements around sharpness, brightness, viewing angle, and the event's aesthetic concept determine the choice.
Professional projection surfaces include tensioned-frame screens in various fabrics, rear-projection film, transparent scrim for ghost and hologram effects, and architectural surfaces used for projection mapping. Selection must account for reflective properties (gain), surface texture, load capacity, and handling during transport and setup. Perforated screens also allow sound reinforcement to be placed behind the surface without audible loss.
Relevance in this field
Alongside the projector, the projection surface is the most important factor in image quality. Careful selection based on use case and ambient light is essential for professional results.
Practical example
For a fashion brand's show, a transparent scrim surface (8 × 4 m) is used. The semi-transparency creates a three-dimensional floating-image effect: models appear behind the scrim while projected content overlays the physical stage.
