Image recording system, image recorder and printing data processor

摘要

An image recording system for setting processing contents related to image recording processing on the basis of the types of color components employed for printing data is provided. A donor sheet roll stored in an image recorder is rendered exchangeable in an intermediate stage of image recording, and recording conditions as to all recordable color components and the storage state of rolls are previously registered in a table. A control part of the image recorder compares/collates information of color components on which color separation data are obtained in a raster image processor with the roll storage state and determines necessariness/unnecessariness of roll exchange, for presenting an exchange object and requesting exchange to an operator if necessary. Thus, a proof image finished approximately to a regularly output image from a regular press can be obtained without increasing the number of rolls stored in the image recorder, so far as inks used in regular press and corresponding rolls are present. An operator is required no skill for operations since he/she may not grasp the roll to be exchanged.
