Abstract
One single-stage proofer RIP replaces a conventional setup of two proofer RIP stages in series. Preliminary profile and data processing usually performed at the first of the conventional RIP stages, and source input terminal of the second, are instead performed in a preprocessor at the image-originating or production-hardcopy-printer station. The preprocessor combines production-printer forward and inverse profiles with a profile for the monitor, associated computer or graphics program—to form a single profile that converts monitor signals to perceptual data representing appearance of the predicted production copy. This three-way composite profile is applied to the source terminal of the single-stage proofer RIP.
