Problems solved by technology

[0004] However, the inventors have recognized that this solution is inadequacy in that completing part of the job will often require the operator's personal attention or "services", such as removal of printed products, manual finishing of the finishing station (finishing station) material, or other work
A similar problem arises because the machine system used for product handling cannot serve all printing equipment at the same time

Embodiment Construction

[0021] figure 1 is a block diagram showing a printing press configuration with three printing presses. The box 20 on the left represents the print job that must be executed by the three printing presses 24 , 26 and 28 on the right. The printers can be of any type and do not have to be identical. The job is sent to a print job scheduler 22, which can be implemented with a PC. The print job scheduler 22 divides the print job into partial jobs, and when the print job specifies several prints from one digital file, it preferably divides the job along an existing division of prints or the like. Divisions can also be made at the page level, especially when the print job is a single print of a digital file. Also, the print job scheduler 22 distributes the partial jobs to the respective printing presses. Commands to these printers are sent along arrow 30 , while return signaling is sent along line 32 . Preferably, all connections are made using digital networks such as LANs, WANs...

Abstract

A method and apparatus executes a printing job on a plurality of printer facilities by dividing the printing job into partial jobs and selectively assigning each partial job to a respective printer facility. The assigning of the partial jobs to the printer facilities attains an improved throughput for the printing job. The method structures a job termination pattern by assigning a partial job to a particular printer facility that will complete earlier than a partial job assigned to another printer facility by a time difference based on a predetermined non-zero time interval. Such a time interval may be defined by an operator in advance. All printer facilities involved in a printing job may be assigned respective partial jobs so that their sequence of completion time instants, in compliance with the user-selected time interval, will constitute a monotonously non-decreasing series.

Description

technical field [0001] The invention relates to a method for executing a print job on a plurality of printing devices, said method comprising dividing said print job into partial jobs and selectively assigning each of said partial jobs to a respective printing device, In order to obtain an increased throughput rate for said printing job. [0002] Second only to printing from input data, the present invention also relates to copying, where the original is presented in the form of a tangible product, usually presented on paper. Hereinafter, such copying is also referred to as "printing" for brevity. Background technique [0003] In general, distributing a large and distributable workload to multiple working devices is a well-known solution. Such methods of distributing relatively large print jobs to several printing devices are known in printing technology. Generally, as disclosed in British Patent Application 2 368 954, the workload is distributed in such a way that all pr...
