<p>A plate-making and -mounting control system for a rotary printing press for newspaper production has several printing units ( I ) each having two plate cylinders ( H ) each having several predefined plate-mounting positions ( 5P-A , 5P-B , 5P-C ,...), and a plate maker ( S ) for making a set of printing plates ( P ) for each printing job which are to be manually mounted to the plate cylinders. In order to make sure that the printing plates are all mounted correctly, an assignment controller (1) puts out, in response to the inputting of a required set of printing directions for each newspaper issue, ASSIGNMENT INFO ( B ) indicative of how the set of printing plates ( P ) are assigned to the plate-mounting positions on the plate cylinder ( H ) . A plate-maker controller (2) puts out CONTENTS INFO ( C ) indicative of at least the page number of each printing plate being made. In response to the ASSIGNMENT INFO and CONTENTS INFO a printer controller (3) puts out POSITION INFO ( D ) indicative of the desired plate-mounting position on the plate cylinder to which each printing plate is to be mounted, and causes a printer (6) to print the POSITION INFO on each printing plate that has been made. Reading the POSITION INFO printings on the printing plates after the latter have been mounted to the plate cylinders, readers (7) put out the POSITION INFO readings ( E ) together with self-identificatory READER INFO ( F ). Whether each printing plate is mounted to the correct position on the correct plate cylinder or not is judged on the bases of the POSITION INFO readings and the READER INFO.</p> |
