Abstract: An image forming system capable of using more than four colors for making enlarged prints, such as billboards, which utilizes a recording medium mounted on a rotating cylinder and which is supported so as to prevent deflection, utilizing a plurality of computer controlled spray heads having flow adjusting means which traverse the width of the recording medium and spray a deposition medium onto the recording medium in accordance with scanning signals from an original image to reproduce the image on the recording medium. Each of the spray heads being provided with means for applying colors or coatings in addition to the standard four color processing. The invention also includes apparatus and processes for mirror image forming on opposite sides of the recording medium and/or forming images on the recording medium using a translucent recording medium.
