The purpose-built spray rig
Tracks are laid at the base and at the top of the screen frame, and a spray rig tower is assembled and fitted to the two tracks. The rig can move left and right so that the spray gun can cover all of the screen. A laser control ensures that the spray gun is always an exact distance away as it makes its way up and down the screen, spraying a special silver paint that will ensure that light is reflected in straight lines off the screen. It is silver because a white screen would refract the light and this would cause ghosting of the image.
