INSPECTION DEVICE FOR PLATE MAKING

摘要

PROBLEM TO BE SOLVED: To prevent the repetition of the mistake of same output by extracting a difference between an initial layout data and a history layout data, thereby making the layout data a past correction object. SOLUTION: A plate making system 2, in order to perform a film output again, receives inputs of layout data prepared by a layout device such as DTP and full original image data to generate an initial layout data and outputs the same to a difference point extraction means 6. A history layout data control means 5 retrieves the hystory layout data whose belongings correspond to the initial layout data among the stored hystory layout data and outputs the same to the means 6. The means 6 compares the history layout data with the initial layout data and outputs a difference in data therebetween. An output control means 8 suspends film output of the initial layout data.
