Abstract
Abstract The platemaking system is a system that produces a printing plate by using an exposure device 8 to print on original film that has imposition data consisting of multiple page data imposed on photosensitive film. The system is equipped with page data layout device 2 and exposure device 8. Page data layout device 2 indicates page layout data that contains positioning information and size information of each page data for the purpose of impositioning multiple page data on photosensitive film. Based on that page layout data, each page data is laid out at the imposition position of the photosensitive film, imposition data is created and the indicated page layout data is output to exposure device 8. Exposure device 8 receives the page layout data via network line NL and moves the original film to the corresponding position in accordance with the received page layout data after which the exposure process is carried out. The device is equipped with keyboard 14 to indicate page layout data for the purpose of impositioning multiple page data on original film. Page data layout device 2 lays out corresponding page data in response to page layout data when the page data corresponding to the page number specified by page layout data is prepared and then creates imposition data. Further, when the page data is not prepared, page data layout device 2 lays out dummy page data in response to page layout data in place of page data and then creates imposition data.
