Printed Material Inspection Area Switching for Front-Back Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for front and back coincidence inspection in printed materials require manual setting adjustments on both sides, placing a heavy burden on operators due to the need to change settings and search for corresponding inspection areas.
Innovation Solution
An inspection system and method that allows easy setting of inspection areas by designating and switching between inspection areas on the front and back sides of printed materials, facilitating automatic synchronization of settings through user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual setting adjustment is performed for each side separately, then inspection accuracy is maintained, but operator burden increases significantly
Solution Approach 1:
The patent merges the setting operations for front and back sides by allowing operators to designate inspection areas on one side and automatically generating corresponding areas on the other side. This combining of operations reduces the time and effort required for setting inspection areas while maintaining inspection accuracy.
Solution Approach 2:
The system performs preliminary action by automatically generating the corresponding inspection area on the second side based on the designation made on the first side. This preliminary generation of settings eliminates the need for manual adjustment on both sides, significantly reducing operator burden and setup time.
2Productivity
If automatic inspection area generation is implemented, then operator burden is reduced, but setting flexibility may be limited
Solution Approach 1:
The system implements dynamic functionality by allowing operators to switch between automatically generated inspection areas and manually adjustable areas. This dynamic adaptability enables the system to maintain high productivity through automatic generation while preserving flexibility when operators need to adjust settings for specific inspection requirements.
Solution Approach 2:
The inspection area setting system serves multiple functions: it can automatically generate corresponding areas based on designations, allow manual adjustment of generated areas, and switch between different sides for designation. This multi-functionality ensures both productivity and adaptability are achieved.

AI summary
An inspection system obtains respective scanned images by reading a first side and a second side of a printed material, and inspects the printed material by comparing the respective obtained scanned images with reference images. In a case where a front and back coincidence inspection is set, the inspection system designates an inspection area to be subject to the front and back coincidence inspection, and switches between displaying a state in which a first inspection area of the first side to be subjected to the front and back coincidence inspection is selected and a state in which a second inspection area of the second side to be subjected to the front and back coincidence inspection is selected, in accordance with an operation of a user.
