Spot Color Patch Inspection Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques are inefficient in increasing the number of colors to be inspected and included in a print image, making color difference inspections in printing processes cumbersome and costly.
Innovation Solution
An information processing device that obtains color information and inspection results to determine the number of colors to be printed as patches based on inspection data, adjusting the number of patches according to the color difference inspection results, thereby optimizing the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of colors to be inspected is increased, then the inspection coverage is improved, but the cost and man-hours increase
Solution Approach 1:
The system performs color difference inspections and uses the results to dynamically adjust which colors are inspected in subsequent printings. Colors that have already been inspected and confirmed are excluded from future inspection lists, creating a feedback loop that reduces redundant inspections while maintaining comprehensive coverage.
Solution Approach 2:
The system discards colors from the inspection list after they have been inspected and confirmed to meet color difference standards. These colors are effectively removed from the inspection process until conditions change, reducing the number of colors that need to be continuously monitored without compromising quality.
2Reliability
If the number of colors to be inspected is increased, then the inspection coverage is improved, but the cost increases
Solution Approach 1:
The system uses inspection results to feedback into the inspection planning process, dynamically adjusting the inspection list to include only colors that have not yet been confirmed. This eliminates redundant inspections and reduces the overall cost of the inspection process while maintaining complete coverage over time.
Solution Approach 2:
Instead of inspecting all colors in every printing operation, the system performs partial inspections only on colors that need verification based on previous results. This reduces the excessive action of repeating full inspections while ensuring necessary quality checks are performed.
3Manufacturing precision
If all colors are inspected in every printing, then color accuracy is ensured, but the process becomes cumbersome
Solution Approach 1:
The inspection process is segmented into two groups: colors that have been inspected and confirmed, and colors that require inspection. This segmentation allows the system to manage the inspection process more efficiently by only focusing on colors that need verification, reducing operational complexity while maintaining color accuracy.
Solution Approach 2:
The system performs preliminary inspections on colors before they are added to the confirmed list. By conducting inspections in advance and maintaining a record of confirmed colors, the system simplifies the actual printing process by eliminating the need to re-inspect already-verified colors, making the overall process less cumbersome.

AI summary
An information processing device includes an obtainer configured to obtain color information of a spot color patch targeted for a color difference inspection and inspection result information indicating a result of the color difference inspection for the spot color patch, a determiner configured to determine, among colors included in image data, a color to be printed as the spot color patch based on the color information and the inspection result information, and a print controller configured to cause a printing device to print the image data and the spot color patch of the color determined by the determiner. The determiner is configured to change the number of colors to be printed as the spot color patch based on the inspection result information on the colors included in the image data.
