Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In color quality verification of printed materials, users need to manually determine which color patches to check and which adjustment functions to execute based on verification results, which is time-consuming and requires knowledge of the process.
Innovation Solution
A system that includes a processor configured as a color verification unit to execute color verification using colorimetric values and a determination unit to automatically select adjustment functions for the image forming apparatus based on verification results, eliminating the need for user knowledge in selecting adjustment functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual determination of color patches and adjustment functions is performed by users, then flexibility and adaptability are maintained, but operation complexity and time consumption increase
Solution Approach 1:
The determination unit automatically determines which color patches to check and which adjustment functions to execute based on the color verification results, eliminating the need for manual user determination. The system serves itself by automatically interpreting verification data and selecting appropriate adjustment functions without requiring user expertise or time investment.
2Productivity
If automatic determination of adjustment functions is implemented, then productivity and efficiency are improved, but device complexity increases
Solution Approach 1:
The determination unit acts as an intermediary component between the color verification unit and the adjustment function execution. It receives color verification results, processes this information, and automatically selects appropriate adjustment functions, serving as a mediating layer that simplifies the overall system operation while improving productivity.
3Measurement precision
If color verification is performed on all color patches, then measurement precision is maintained, but processing time and complexity increase
Solution Approach 1:
Instead of uniformly processing all color patches, the determination unit identifies and focuses on specific local regions (particular color patches) based on the color verification results. This selective approach maintains measurement precision for critical areas while reducing overall processing time by excluding less important patches from detailed analysis.

Data Source
AI summary
A system includes at least one processor configured to function as a color verification unit configured to execute color verification by using a colorimetric value acquired by colorimetry of a sheet output by an image forming apparatus, and a determination unit configured to determine an adjustment function to be executed by the image forming apparatus or an image processing apparatus connected to the image forming apparatus from among a plurality of adjustment functions, based on a result of the color verification.
