Inkjet Color Calibration Using Server Feedback and Ink Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink jet printers face issues with forming colors that deviate significantly from user desires due to manufacturing errors in head units and differences in ink characteristics, leading to an excessive burden on users adjusting the formed colors.
Innovation Solution
An ink jet system that communicates with a server to acquire and transmit information about head units and ink types, receiving reference color information to adjust drive waveforms and ink ejection amounts for precise color formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple head units and ink types are used to form colors, then color variety is improved, but color accuracy deteriorates due to manufacturing errors and ink characteristic differences
Solution Approach 1:
The system transmits head unit information and ink information to a server, which generates reference color information based on this feedback. This reference color information is then used to adjust drive waveforms and ink ejection amounts, creating a closed-loop feedback system that compensates for manufacturing variations and ink characteristic differences, thereby maintaining color accuracy while using multiple head units and ink types.
Solution Approach 2:
The system changes parameters such as drive waveform characteristics and ink ejection amounts based on the reference color information received from the server. By dynamically adjusting these parameters according to the specific head unit and ink type being used, the system compensates for manufacturing errors and ink variations, achieving accurate color formation with diverse head units and ink types.
2Manufacturing precision
If reference color adjustment is performed manually, then color accuracy can be improved, but user burden increases excessively
Solution Approach 1:
The system performs self-service by automatically transmitting head unit and ink information to the server, which then generates and returns reference color information. The system automatically adjusts drive waveforms and ink ejection amounts based on this information without requiring manual user intervention for color calibration, thereby maintaining color accuracy while significantly reducing user burden.
Solution Approach 2:
The system performs preliminary actions by automatically transmitting information to the server and obtaining reference color information before actual printing operations. This preliminary calibration process eliminates the need for users to perform manual color adjustments during operation, reducing user burden while ensuring color accuracy is achieved in advance.

AI summary
Provided is an ink jet system configured to communicate with a server, the ink jet system including: a first head unit that ejects a first type of ink onto a recording medium; a second head unit that ejects a second type of ink onto the recording medium; an acquisition section that acquires one or both of first information regarding the first head unit and the second head unit, and second information regarding the first type of ink and the second type of ink; a transmitter that transmits one or both of the first information and the second information to the server; and a receiver that receives, from the server, reference color information for forming a reference color on the recording medium, which is generated based on one or both of the first information and the second information.
