Printed Material Inspection With Sequential Number Region Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inspection methods for printed materials require separate setting of inspection regions for odd and even pages, even for single-sided printing, leading to operational burdens for operators.
Innovation Solution
An inspection system and method that allows for setting a sequential number inspection region for all pages at once, particularly in single-sided printing, by duplicating the inspection region and performing data collating inspection across all pages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate inspection regions are set for odd and even pages, then inspection accuracy is maintained, but operational burden increases
Solution Approach 1:
The patent applies the copying principle by duplicating the inspection region settings from odd pages to even pages automatically. The controller stores inspection region information for odd pages and automatically generates corresponding settings for even pages, eliminating the need for manual separate configuration while maintaining inspection accuracy across all pages
Solution Approach 2:
The patent implements preliminary action by pre-storing inspection region information for odd pages in the controller. This pre-configured data is then automatically applied to even pages during the inspection process, reducing operational burden by eliminating the need to manually set up each page's inspection regions separately
2Reliability
If inspection regions are set for each odd and even page, then comprehensive inspection is achieved, but setting time increases
Solution Approach 1:
The controller automatically copies inspection region settings from odd pages to even pages based on stored information. This copying mechanism ensures comprehensive inspection coverage across all pages while dramatically reducing the time required for setting up inspection regions, as operators only need to configure odd pages manually
Solution Approach 2:
The patent merges the configuration process for odd and even pages into a single operational workflow. By combining the settings for both page types through automatic duplication, the system achieves comprehensive inspection coverage while minimizing the total setting time required
3Measurement precision
If manual setting of inspection regions is required for each page, then inspection precision is maintained, but productivity decreases
Solution Approach 1:
The system implements self-service by automatically generating even page inspection settings based on stored odd page information. The controller performs this duplication autonomously without requiring manual intervention for each page, thereby maintaining inspection precision while significantly improving overall inspection efficiency and productivity

AI summary
An inspection system comprising an image forming apparatus that generates a printed material in accordance with a print job including print data and imposition information, and an inspection apparatus inspects the printed material. The inspection apparatus obtains a scan image of the printed material, makes inspection settings for a reference image, performs inspection by comparing the scan image and the reference image, and controls, in a case where the inspection settings include sequential number inspection and the imposition information indicates single-sided printing, to duplicate an inspection region set in the inspection settings for all pages. In a case where the sequential number inspection is set, the inspection apparatus performs data collating inspection for comparing the number set in the inspection settings with a collation value.
