Solution Overview
Problem
In commercial printing, selecting the appropriate inline colorimetric sensor for color chart printing is complex due to differences in paper compatibility, sensor positioning, and varying colorimetric accuracy and speed, leading to inefficiencies and potential print errors.
Innovation Solution
A color management system that automatically selects a compatible colorimetric sensor based on the designated paper, using a server and image forming apparatus to store and retrieve sensor and paper information, ensuring correct sensor selection for color adjustment processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple inline colorimetric sensors are mounted in the image forming apparatus, then colorimetric accuracy and speed can be optimized, but device complexity increases and it becomes difficult to select the appropriate sensor for specific paper types
Solution Approach 1:
The system enables automatic sensor selection based on paper type detection. The image forming apparatus autonomously identifies the paper type and selects the most suitable colorimetric sensor without requiring manual intervention or complex user decision-making processes.
Solution Approach 2:
Paper type information is detected and stored in advance before the colorimetric measurement process begins. This preliminary detection allows the system to pre-select the appropriate sensor, eliminating the complexity of real-time sensor selection and ensuring optimal measurement conditions are established beforehand.
2Measurement precision
If manual sensor selection is required based on paper compatibility, then colorimetric accuracy can be maintained, but user work efficiency decreases due to the need for detailed knowledge of sensor-paper compatibility
Solution Approach 1:
The system performs automatic sensor selection based on detected paper type, eliminating the need for users to manually select sensors or possess specialized knowledge about sensor-paper compatibility. This self-service approach maintains measurement precision while significantly improving user work efficiency.
Solution Approach 2:
The control unit acts as an intermediary between the paper type detection system and the colorimetric sensors. It automatically matches the detected paper type with the most suitable sensor based on pre-stored compatibility information, shielding users from the complexity of sensor selection while ensuring accurate measurements.
3Reliability
If the wrong inline sensor is selected for the paper type, then print errors occur requiring re-printing, but the system becomes more complex requiring additional validation mechanisms
Solution Approach 1:
The system implements automatic validation through feedback mechanisms. The control unit continuously monitors the match between detected paper type and selected sensor, and can automatically adjust or re-select sensors to prevent print errors, eliminating the need for complex manual validation systems.
Solution Approach 2:
Sensor compatibility validation is performed in advance before the colorimetric measurement begins. The system pre-verifies that the selected sensor is appropriate for the detected paper type, preventing print errors before they occur and avoiding the need for complex real-time validation mechanisms.

AI summary
In a color management system including a server and an image forming apparatus, the server stores information of a colorimetric sensor and paper information corresponding to the colorimetric sensor, obtains information of a colorimetric sensor mounted in the image forming apparatus, designates paper to use when executing a color adjustment process of the image forming apparatus, and, based on the stored paper information, selects a colorimetric sensor of the image forming apparatus corresponding to the designated paper. The image forming apparatus comprises causes a printer engine to print a chart on the designated paper in accordance with a color adjustment job for executing the color adjustment process, and measures a colorimetric value of the printed chart using the selected colorimetric sensor.
