Innovation Solution
A printing system that includes an image forming apparatus and an information processing apparatus, allowing for the detection of paper characteristics, printing of a color patch chart, and automatic creation of a color profile through a single user operation, integrating paper characteristic detection, colorimetry, and profile registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate operations are used for registering paper characteristics and creating color profiles, then each operation can be performed independently with existing functionality, but the user operation becomes complex and time-consuming
Solution Approach 1:
The patent combines paper characteristic registration and color profile creation into a single integrated operation. The medium sensor detects paper characteristics, the color patch is printed, and the colorimetric sensor measures the color patch all within one workflow, eliminating the need for separate operations and reducing user burden while maintaining functional independence
Solution Approach 2:
The printing system is designed to perform multiple functions through a single operation sequence: paper characteristic detection, color patch printing, and color measurement. This multi-functional approach allows the system to handle both paper registration and color profile creation without requiring users to switch between different operational modes
2Productivity
If paper characteristics are registered first, then color profiles can be created subsequently, but the process requires multiple sequential steps increasing time consumption
Solution Approach 1:
The system performs preliminary paper characteristic detection using the medium sensor before printing the color patch. This preliminary action ensures that the paper characteristics are captured in advance, allowing the subsequent color profile creation to proceed efficiently without requiring re-detection or re-measurement, thus reducing overall process time
Solution Approach 2:
The patent maintains continuous useful action by seamlessly transitioning from paper characteristic detection to color patch printing and then to color measurement. The workflow is designed so that each step flows directly into the next without idle time or repeated operations, maximizing productivity while minimizing time loss
