A photographic imaging process for producing large-format display media is disclosed. The process begins with a graphic digital file, which is sent to a computer having raster image processing (RIP). The RIP prepares data in four-color screen separation. The processed data is sent to an imagesetter, which sequentially or concurrently, exposes a photosensitive medium, preferably a clear-based silver halide film having a surface emulsion coated thereon containing three imaging media each capable of forming a color image upon imagewise exposure and processing. The clear based halide film records the screened color information for cyan, yellow, magenta and black. The silver halide film is then processed in RA-4 and compatible chemicals producing a clear-based color negative representing a composite of the four-color separations. The processed film is then exposed by a conventional optical enlarging system to a negative receiving material in order to produce a large-format display media such as a banner.
