<p>A system (10) for automatically reproducing an image (95) on a large suface (90), such as the external wall of a building or a billboard. The system (10) includes a computer (12), a translator program (20), a controller card (30), and an image reproduction machinery (40). The computer (12) is programmed with the translating program (20), which converts a downloaded image file into a data file capable of being used by the controller card (30). The controller card (30) is used to control drivers (32) that control various motors (47, 52, 76) on the image reproduction machinery. The image production machinery (40) comprises a guide rail (42), a carriage (50), and a medium head assembly (60). The guide rail (42) is suspended adjacent to the surface (90) to be painted. During operation, the guide rail (42) moves along one axis of the surface (90) and the carriage (52) moves longitudinally over the guide rail (42). The medium head assembly (60) contains a plurality of airbrushes (66) that are equally spaced apart with their tips aimed at a single point on the surface (90), thereby producing a single pixel of various colors and shades.</p> |
