Abstract

A prepress system comprises a raster image processor for developing first print image data to display resolution to create first raster image data, and for developing second print image data to the display resolution to create second raster image data. A plate image inspection processor executes a plate image inspection process by comparing the first and second raster image data, and displays on a display device the result of the plate image inspection process.
