Abstract
Plate-image-inspection RIP data CD2, CD3 are prepared using the same RIP processing conditions from two print image data prepared in different steps of the prepress process, and inspection results are obtained by comparing these data CD2, CD3. Plate-image-inspection RIP data CD2, CD3 can be prepared in several methods: (1) a method for RIP processing respective non-RIP data using standard RIP processing conditions; (2) a method for respectively converting two RIP data to standard RIP processing conditions; and (3) a method for converting one of two RIP data such that it conforms to the RIP processing conditions of the other.
