IMAGE PROCESSING SYSTEM, IMAGE GENERATION-OUTPUT CONTROL APPARATUS, AND METHOD OF PROCESSING INFORMATION, CONFIGURED TO USE IMPOSITION CONVERSION

An image processing system for executing a plurality of processes includes a process execution control apparatus, and image generation-output control apparatuses of different types. The process execution control apparatus includes a process execution controller to control the processes, and to transmit a command information to the image generation-output control apparatuses. Each of the image generation-output control apparatuses includes a command information converter to convert the command information to a format processable by the image generation-output control apparatus, an imposition convertor to convert initial designation information to imposition process information processable by the image generation-output control apparatus, and an image drawing information generator to generate image drawing information.
