Printer Color Verification Automation via Embedded Chart Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color verification systems for printers require manual switching of colorimetric measurement conditions for each verification, making multiple color verifications complex and time-consuming, as different conditions need to be set for each certification and print profile.
Innovation Solution
An information processing apparatus that automatically obtains and switches colorimetric measurement conditions for each chart during measurement, allowing for sequential colorimetric measurement and verification of multiple charts with a single measurement job, using embedded code images to determine the necessary conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual switching of colorimetric measurement conditions is performed for each verification, then measurement accuracy is maintained, but operation complexity and time consumption increase
Solution Approach 1:
The measurement device automatically acquires and switches between different colorimetric measurement conditions based on embedded identification information in the charts, eliminating the need for manual condition switching by the user while maintaining measurement accuracy
Solution Approach 2:
Different colorimetric measurement conditions are pre-configured and stored in the measurement device, and the appropriate conditions are automatically selected based on identification information embedded in each chart, preparing the measurement parameters in advance
2Measurement precision
If multiple color verifications are performed separately, then each verification accuracy is ensured, but productivity decreases
Solution Approach 1:
Multiple color verification processes are merged into a single measurement job, allowing multiple charts with different verification requirements to be measured sequentially in one operation, thereby improving productivity while maintaining verification accuracy
Solution Approach 2:
The measurement device is designed to handle multiple types of color verifications universally by automatically switching measurement conditions based on embedded identification information, enabling one device to perform multiple verification functions
3Reliability
If separate measurement jobs are created for each verification, then measurement conditions are properly controlled, but device complexity increases
Solution Approach 1:
Embedded identification information (such as barcodes or QR codes) serves as an intermediary carrier that contains measurement condition data, allowing the system to automatically retrieve and apply appropriate measurement conditions without complex manual configuration
