An objective of the present invention is to enable the use of identification information, which is usable in a traceability system, in the management of a machine for manufacturing a package material. Provided is a management system of a manufacturing machine for manufacturing a package material which is usable in the distribution of articles, the system including: printing devices for, in a process of manufacturing a package material, printing on the package material unique identification information which is usable in traceability in the distribution of articles; identification information reading devices which are installed downstream of the printing devices for reading the identification information; and machine management devices for acquiring individual characteristic information of the package material, and managing the manufacturing machine on the basis of machine management information in which the acquired individual characteristic information is associated with the identification information read by the identification information reading devices.

Package material manufacturing machine management system

Regarding a cardboard sheet-cutting device, a cardboard sheet-cutting control unit and a cardboard sheet-manufacturing apparatus, continuous cutting is made during job changes, in which the cardboard sheet cutting width changes, without stopping conveyance of the cardboard sheets, by a printing unit for printing cutting marks on a double-faced cardboard sheet; a slitter scorer for cutting the double-faced cardboard sheet to a specified width; a cutoff for cutting the double-faced cardboard sheet to a specified length; a mark detector for detecting cutting marks; a movement unit for moving the mark detector along the width direction of the double-faced cardboard sheet; and a cutting control unit for performing control to actuate the cutoff on the basis of the detection results of the mark detector and moving the mark detector using the movement unit on the basis of job-change timing data and post-job change mark position information.

To prevent incorrect recognition of marks on a web, and to lighten a load to memory and arithmetic systems associated with mark recognition, a control apparatus for a printing machine includes a positional relationship acquisition means for previously obtaining a positional relationship between a position in a web traveling direction of each of the marks and a target cutting-off position of the web, and a detection timing control means for controlling mark detection timing so that the detection of each of the marks by a mark detector is performed during a specified period based on the positional relationship.

A printed matter inspection device includes a light source that irradiates a color printed matter as an inspection object with illuminating light, a detector that detects the quantity of reflected light of each of a plurality of different color light beams from among reflected light reflected by the inspection object, and a controller that controls a timing of acquiring a detection signal of each of the color light beams from the detector. The controller acquires a detection signal of selected one of the different color light beams for one of a plurality of non-print areas on the inspection object. The controller acquires a detection signal of newly selected one of the different color light beams for another one of the non-print areas.

A blanket cylinder washing method for use in a web offset printing press. A blanket cylinder is rotated independently of running of a web, with the blanket cylinder thrown off, preferably, the blanket cylinder is rotated at a speed Vhigher than a running speed Vof the web, and the blanket cylinder is washed. It is thereby possible to decrease the amount of spoilage generated when the blanket cylinder is washed.
