Print Inspection Interface for Precursor Quality Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image formation apparatuses may fail to recognize the degree of a precursor abnormality, leading to potential waste of image-formed media due to undetected issues exceeding detection criteria in subsequent jobs.
Innovation Solution
An inspection system and method that compares captured images with reference images, determining normality or failure, and provides notifications and counts for degrading print quality even when inspections are normal, allowing for proactive correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the abnormality detection level is strictly set to detect precursor abnormalities, then the ability to detect precursors is improved, but the user's ability to recognize the degree of precursor is worsened
Solution Approach 1:
The patent introduces a new dimension of information display by showing the difference image between the captured image and reference image alongside the inspection result. This additional visual dimension allows users to perceive the degree and location of precursor abnormalities spatially, transforming abstract detection data into intuitive visual information that preserves both detection precision and user comprehension.
2Device complexity
If the inspection system only displays normal/failure results, then the system complexity is reduced, but the productivity is worsened due to waste of image-formed media
Solution Approach 1:
The patent enables preliminary action by providing users with visual information about precursor abnormalities before they develop into actual failures. The difference image display allows users to identify and address issues proactively, preventing future media waste and improving productivity without requiring complex additional hardware systems.

AI summary
The present disclosure is directed to inspection system including a controller that, in an inspection of comparing a captured image obtained by capturing a print product generated by an image formation device and a reference image, determines whether the captured image is normal or a failure, the system comprising a display I/F that, in a state in which a quality of the print product by the image formation device degrades even in a case where a result of the inspection is normal, announces occurrence of the state and a count at which the state has occurred.
