Dynamic CMS Profile Selection for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses face challenges in maintaining optimal printing quality across various environments due to the use of fixed Color Management System (CMS) profiles, which fail to account for seasonal temperature variations and other factors like usage history and document type.
Innovation Solution
An image processing method that measures the state of the image forming apparatus and selects the appropriate CMS profile based on factors such as temperature, usage history, and document type to generate optimized printing data, allowing for dynamic adjustment of printing settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed CMS profile is used, then the device complexity is reduced and ease of operation is improved, but printing quality deteriorates due to inability to adapt to temperature variations and usage history
Solution Approach 1:
The patent implements dynamic CMS profile selection by measuring the actual state of the image forming apparatus (temperature, humidity, usage history) and automatically selecting the most appropriate CMS profile from multiple stored profiles based on the measured state. This transforms the fixed profile system into a dynamic one that adapts to changing environmental and operational conditions, thereby maintaining high printing quality without requiring manual user intervention to select profiles.
2Manufacturing precision
If multiple CMS profiles are stored and selected dynamically, then printing quality adapts to various environments, but device complexity increases
Solution Approach 1:
The patent implements self-service by having the image forming apparatus automatically measure its own state (temperature, humidity, usage history) and autonomously select the appropriate CMS profile without requiring user intervention. The system serves itself by performing the measurement and selection processes automatically, which reduces the operational burden on users while maintaining the complexity of managing multiple profiles in the background.
3Adaptability or versatility
If CMS profile is selected based on measured state, then adaptability to printing environments improves, but measurement and selection process adds time
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple CMS profiles in the image forming apparatus before actual printing occurs. When printing is needed, the system quickly measures the current state and selects from pre-prepared profiles rather than creating or calculating profiles in real-time. This preliminary preparation significantly reduces the time required for profile selection during the actual printing process while maintaining high adaptability to different environments.
