Print Color Management Apparatus Dynamic Calibration Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current print color management systems lack flexibility in calibration processes, as they rely on fixed error calculations for determining when to perform calibration, which can lead to either excessive or inadequate colorimetric measurements, resulting in either cumbersome processes or overlooked abnormal states in color management.
Innovation Solution
A print color managing apparatus and method that includes a color management condition setting section, a colorimetric data acquirer, and an execution period determiner, which assesses colorimetric values over multiple printing times to determine a suitable calibration schedule, providing flexible and timely calibration based on actual print color variation characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If colorimetric measurements are made at short intervals, then color accuracy monitoring is improved, but the printing process and colorimetric measurement process become too troublesome to perform
Solution Approach 1:
The printing device performs colorimetric measurements automatically during the printing process without requiring separate manual measurement operations. The measurement unit is integrated into the printing device, enabling it to measure colorimetric values of printed images automatically as part of the printing workflow, thus eliminating the need for separate measurement steps while maintaining monitoring precision.
2Ease of operation
If colorimetric measurements are taken over long intervals, then the measurement process becomes simpler, but abnormal states may be overlooked that fall out of a color management range
Solution Approach 1:
The system performs colorimetric measurements continuously or at frequent intervals during the printing process, maintaining continuous monitoring of color accuracy. The measurement unit measures colorimetric values at multiple points throughout the printing workflow, ensuring that abnormal color states are detected promptly without requiring long intervals between measurements, thus maintaining both reliability and operational simplicity.
3Ease of manufacture
If fixed error calculation methods are used to determine calibration timing, then the calibration process becomes standardized, but it cannot adapt to different printing device configurations and purposes
Solution Approach 1:
The system dynamically determines calibration timing based on actual measured colorimetric values and their variations over time, rather than using fixed predetermined intervals. The calibration determination unit analyzes the trends and variations in colorimetric measurements to adaptively decide when calibration is needed, allowing the system to adjust to different printing device configurations, usage patterns, and environmental conditions while maintaining standardized calibration procedures.

AI summary
Color management conditions concerning management of color accuracy in a printing apparatus are set, and colorimetric values of color patches printed as color specimens by the printing apparatus are acquired in association with a printing time of the color patches. An execution period for a calibration process on the printing apparatus is determined based on a plurality of colorimetric values, which are acquired at a plurality of printing times, and the color management conditions, which have been set.
