Abstract: A technique is provided with which it is possible to effectively consume a plurality of continuous base materials with different remaining amounts. A job list and a continuous paper list are prepared. The job list registers job attribute information that includes print length information that indicates the length of continuous paper necessary for printing of each print job. The continuous paper list registers continuous-base-material attribute information that includes paper remaining information that indicates a remaining length of each roll of continuous paper. Then, a job batch is generated in accordance with the continuous-paper attribute information and the job attribute information. The job batch defines one roll of continuous paper and a print job, the continuous paper being selected from among the continuous paper list, the print job being extracted from among the job list and printable on the selected continuous paper.

Abstract: A printing system includes a book body printing section including a book body printing machine and outputting book bodies sequentially, and a cover printing section including a cover printing machine and outputting covers sequentially. The book body printing machine and the cover printing machine respectively receive printing order data indicating a printing order with regard to a plurality of jobs from a print control apparatus, and perform printing in the printing order indicated by the printing order data. The print control apparatus generates the printing order data, so that an inserting order in unit of job to a bookbinding machine of the book bodies output from the book body printing section coincides with an inserting order in unit of job to the bookbinding machine of the covers output from the cover printing section.

Abstract: A sphere size measuring unit (15) measures respective diameters of an object sphere in the course of processing and a standard sphere made of the same material as that of the object sphere and furthermore having a target diameter of the object sphere. A size difference calculation unit (161) calculates a size difference between the diameter of the object sphere and the diameter of the standard sphere. A determination unit (162) compares the obtained size difference with a threshold value so as to determine whether or not the diameter of the object sphere reaches the target value.

Abstract: A construction information extraction section acquires information about a construction of a document from order information about document production acquired by an order information acquisition section. A job definition section defines jobs for producing a component, based on the construction information, and also defines stages to be executed in each of the jobs. A job assignment section assigns the defined jobs to job workers. A progress management section acquires information about progress on each of the stages included in the jobs assigned to the job workers. This achieves production management adapted to the realities at the site of actual production such that each job for the production of the document is subdivided into a plurality of parts which in turn are assigned to the job workers.

Abstract: An image processor for forming an easy-to-see image by broadening the significant band of image data received from a logarithmic (LOG) image sensor to enhance the contrast of the image. The LOG image sensor generates an output in response to the light, with the output voltage being a logarithm of the intensity of the light received. The image processor extracts only those pixel data in the significant band out the image data received from the LOG image sensor in accordance with the distribution of the voltage of the signals. In order to form an easy-to-see image, the processor expands the voltage band, assuming that the output voltage has a linear dependence on the intensity of light received by the LOG image sensor. The resultant image has an wider band in voltage, which enhances the contrast, and hence the visibility, of the image.
