Printing System Code Association for Post-Processing Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing printing systems, offline post-processing of printed materials often leads to errors due to the lack of a unit for associating print job data with post-processing job data, resulting in potential mistakes during finishing processes like cutting or stapling.
Innovation Solution
A printing system that includes a storage unit for associating print job data and post-processing job data, a printing unit that prints a code on the media, and a code reading unit to select the correct post-processing job based on the read code, ensuring accurate post-processing even after printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If print job data and post processing job data are not associated, then the system is simpler to operate, but errors occur during offline post-processing
Solution Approach 1:
The patent uses a code (such as barcode or QR code) that copies the print job identification information and prints it on the media. This code serves as a simplified representation of the print job data, enabling automatic identification and association during post-processing without requiring complex data structures or manual tracking systems.
Solution Approach 2:
The printed code acts as an intermediary between the print job data and the post processing job data. Instead of directly linking complex data structures, the code provides a simple bridge that the post processing machine reads to automatically retrieve and execute the correct post processing job, eliminating the need for manual association while maintaining system simplicity.
2Productivity
If printing and post processing are performed online, then processing speed is improved, but flexibility for offline processing is reduced
Solution Approach 1:
The printed code serves multiple functions: it identifies the print job for online processing and simultaneously provides the necessary information for offline post-processing. This universal identifier enables the system to adapt to both online and offline workflows without requiring different identification mechanisms, maintaining both productivity and flexibility.
3Reliability
If manual association of print job data and post processing job data is used, then device complexity is reduced, but operator errors increase
Solution Approach 1:
The system enables self-service automation where the post processing machine automatically reads the printed code, retrieves the corresponding post processing job data, and executes the appropriate processing without operator intervention. This eliminates manual association errors while keeping the system simple, as the automation handles itself through the printed code identifier.

AI summary
A printing system includes a storage unit that associates and stores print job data and post processing job data; a printing unit that prints a code regarding the association on media when an image is printed on the media based on the print job data; a code reading unit that reads the code that is printed on the media; and a post processing unit that selects the post processing job data that is associated from the storage unit based on the read code and performs the post processing with respect to the media based on the selected post processing job data.
