Print Job Post-Processing Control to Eliminate Redundant Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems waste resources and ink due to unchanged post-processing settings between successive print jobs, leading to unnecessary printing of codes and post-processing instructions.
Innovation Solution
A printing apparatus and control system that compares post-processing settings between consecutive print jobs and adjusts print settings to avoid printing unnecessary information between images when settings do not change, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a code is printed corresponding to each of all print jobs, then post-processing can be performed on printed matter, but waste of medium and ink occurs when post-processing settings do not change between successive print jobs
Solution Approach 1:
The system performs post-processing information printing partially - only when post-processing settings actually change between successive print jobs. The control unit compares post-processing settings of current and previous print jobs, and suppresses printing of post-processing information when settings remain unchanged, thereby avoiding unnecessary consumption of medium and ink while maintaining reliable post-processing capability when needed
2Reliability
If post-processing information is printed for every print job, then post-processing settings can be applied accurately, but printing efficiency decreases due to unnecessary printing operations
Solution Approach 1:
The system applies partial action by printing post-processing information only when necessary - specifically when a change in post-processing settings is detected between successive print jobs. The control unit compares settings and conditionally suppresses printing operations, thereby maintaining accurate post-processing setting application while improving printing efficiency by eliminating redundant printing actions
3Productivity
If the printing unit prints two or more designated print jobs, then batch processing efficiency is improved, but resource waste increases if post-processing settings repeat across multiple jobs
Solution Approach 1:
When the printing unit processes two or more designated print jobs in batch mode, the control unit compares post-processing settings across successive jobs and suppresses printing of post-processing information for jobs with unchanged settings. This partial action approach maintains batch processing efficiency while reducing ink and medium consumption by avoiding redundant post-processing information printing across multiple jobs
4Reliability
If post-processing information is printed between images, then post-processing can be performed correctly, but the amount of printed material increases unnecessarily
Solution Approach 1:
The system prints post-processing information between images only partially - specifically only when post-processing settings change between successive print jobs. The control unit detects setting changes and conditionally suppresses the printing of post-processing information, thereby maintaining correct post-processing capability while reducing the volume of printed material by eliminating unnecessary repetitions

AI summary
In a printing apparatus, when an image printed based on image data of an n-th print job as an n-th print target among designated two or more print jobs is an n-th image, and an image printed based on image data of a (n+1)-th print job as a (n+1)-th print target among the designated two or more print jobs is a (n+1)-th image, n-th post-processing setting information and (n+1)-th post-processing setting information are compared to determine whether or not setting of the post-processing needs to be changed, and when the setting of the post-processing does not need to be changed, print setting is changed so as not to print information based on post-processing setting information set to be printed at a position between the n-th image and the (n+1)-th image on the medium.
