Reference Image Orientation Control for Print Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where multiple printing apparatuses are used, changes in apparatus configuration can lead to mismatches between imported reference images and captured images, necessitating re-registration, which is time-consuming and effort-intensive.
Innovation Solution
An inspection system that automatically adjusts the reference image based on the apparatus configuration of the import destination by reversing the front and back of the reference image as needed, allowing for seamless comparison without user intervention.

Engineering Contradiction Analysis
1Ease of operation
If a reference image is imported into another inspection apparatus to avoid re-registration, then the user can inspect the reference image without manually re-registering it, but the imported reference image and captured image may not match due to changes in printing surface, requiring re-registration
Solution Approach 1:
The system performs preliminary actions by automatically determining the printing surface direction (front or back) based on apparatus configuration information before importing the reference image. This preliminary determination allows the system to pre-adjust the reference image orientation, ensuring it matches the captured image when inspection occurs, thereby preventing mismatch without requiring user re-registration
Solution Approach 2:
The inspection apparatus performs self-service by automatically adjusting the reference image orientation based on its own apparatus configuration information. The system independently determines whether to reverse the reference image without user intervention, maintaining reliability of the inspection while preserving the convenience of import functionality
2Reliability
If the user re-registers the reference image to ensure proper matching after apparatus configuration changes, then the reference image and captured image will match correctly, but the process takes time and effort
Solution Approach 1:
The system eliminates the need for user re-registration by performing automatic orientation adjustment based on apparatus configuration information. The inspection apparatus independently processes the reference image orientation, ensuring correct matching without consuming user time or effort
Solution Approach 2:
The system performs the orientation adjustment action in advance before the inspection process begins. By pre-determining the correct orientation based on apparatus configuration, the system prevents the need for time-consuming re-registration operations during actual inspection workflows

AI summary
A first inspection apparatus registers an image scanned from a print product printed by a first printing apparatus as a first reference image, and registers information of a print job related to printing of the image with the image and first configuration information indicating configuration of the first printing apparatus. A second inspection apparatus imports the first reference image registered in the first inspection apparatus and registers the imported first reference image as the second reference image. Based on information of the print job registered with the first reference image, the first configuration information, and the second configuration information indicating the configuration of the second printing apparatus, it is controlled whether the first reference image is registered as the second reference image by reversing a front and back of the first reference image or as the second reference image without reversing the front and back of the first reference image.
