Print Failure Prioritization in Image Inspection Workflows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image inspection technologies in the printing industry are inefficient as they require manual judgment of print failures and do not account for the position and type of print failures, leading to decreased inspection efficiency and unnecessary reprinting.
Innovation Solution
An image processing apparatus that sets priority degrees for print failures based on their position and type, displaying them in order of priority to improve inspection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated inspection is implemented to improve inspection efficiency, then productivity increases, but the complexity of processing and managing large numbers of read images increases
Solution Approach 1:
The patent divides the inspection process into distinct stages: initial automated comparison to detect print-failure regions, followed by selective detailed inspection of only those regions. This segmentation allows the system to maintain high productivity while reducing the complexity of processing entire images, as only problematic areas require intensive analysis.
Solution Approach 2:
The patent extracts and isolates print-failure regions from complete read images for separate processing. By separating the detection of failures from the analysis of failures, the system improves efficiency through automated initial screening while reducing complexity by focusing detailed inspection only on extracted failure regions rather than entire images.
2Manufacturing precision
If all print-failure regions are inspected in detail to ensure quality, then manufacturing precision is maintained, but time consumption increases
Solution Approach 1:
The patent applies different inspection depths to different regions based on their importance and failure characteristics. Critical regions with severe print failures receive detailed inspection, while minor or non-critical regions receive less intensive analysis. This local differentiation maintains manufacturing precision for important areas while reducing overall inspection time.
Solution Approach 2:
The patent performs partial inspection rather than complete inspection of all regions. By applying automated comparison to detect failures and then performing detailed inspection only on detected failure regions rather than entire images, the system achieves sufficient quality assurance with reduced time investment, applying the appropriate level of action to each case.
3Ease of manufacture
If uniform rectangular images are displayed for print-failure regions, then ease of manufacture is improved, but ease of operation deteriorates as users must determine which portions to check with priority
Solution Approach 1:
The patent performs preliminary prioritization and classification of print-failure regions before presenting them to users. The system automatically determines which regions require urgent attention based on failure characteristics, position, and severity, and pre-organizes the display accordingly. This preliminary action eliminates the need for users to independently prioritize regions, improving ease of operation while maintaining simple rectangular display formats.
Solution Approach 2:
The patent incorporates feedback mechanisms that provide users with prioritized information about which print-failure regions to inspect first. The system analyzes failure characteristics and automatically ranks regions by importance, feeding this prioritization information back to users in an organized manner. This reduces the cognitive burden on users while maintaining the simplicity of rectangular image presentation.
