Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color accuracy verification devices only manage color accuracy for individual printers, failing to account for deviations between multiple printers, which can lead to unexpected color accuracy deterioration in shared print jobs, resulting in unscheduled visits and resource wastage.
Innovation Solution
A color accuracy verification system that centrally manages color accuracy across multiple printers, using a colorimeter to measure color values and a device that predicts future color accuracy by analyzing historical data, allowing for timely correction and ensuring consistent print quality across distributed printing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If color accuracy verification is carried out only for one printer, then the verification process is simple, but deviations in color accuracy between multiple printers cannot be detected
Solution Approach 1:
The patent combines color accuracy verification across multiple printers into a unified system. The management device collects colorimetric values from multiple printers, performs centralized verification against desired values, and manages correction workflows across the entire printer fleet, enabling detection of inter-printer deviations while maintaining systematic simplicity
Solution Approach 2:
The management device serves multiple functions: it verifies color accuracy for individual printers, compares color accuracy across multiple printers, manages correction workflows, and provides centralized control. This multi-functional approach allows the system to handle both simple single-printer verification and complex multi-printer coordination without requiring separate systems
2Reliability
If technician visits are increased to ensure color accuracy, then color accuracy can be maintained, but man-hours and operational costs increase
Solution Approach 1:
The system implements continuous feedback by regularly collecting colorimetric values from printers, comparing them against desired values and acceptance criteria, and automatically generating correction workflows when deviations are detected. This automated feedback loop enables proactive color accuracy management without requiring constant technician intervention
Solution Approach 2:
The system performs preliminary verification and prediction of color accuracy deterioration trends before actual color accuracy failures occur. By analyzing historical data and predicting future deviations, the system schedules corrections in advance, preventing color accuracy issues rather than reacting to them, thereby reducing emergency technician visits
3Reliability
If color accuracy verification is performed frequently, then color accuracy can be maintained, but operational time and resources are consumed
Solution Approach 1:
The system performs verification at optimized frequencies rather than continuous monitoring. It collects colorimetric values at intervals sufficient to detect trends and deterioration, balancing verification thoroughness with operational efficiency. The system performs just enough verification to maintain color accuracy without excessive resource consumption
