Color Chart Identification for Printer Quality Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing quality management systems face challenges in efficiently managing and identifying multiple printers, leading to a high burden on users and inadequate printing quality evaluation.
Innovation Solution
A color chart system that includes identification information for each printer, paper type, and printing parameters, allowing for automatic evaluation of printing quality by using color charts printed with unique codes and evaluation patches, enabling effective identification and quality assessment of image forming apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined color chart is printed and read by a color measuring device to perform color adjustment for each printer, then printing quality can be maintained, but there is a large burden on the user to identify each printer when managing a plurality of printers
Solution Approach 1:
The color chart is designed to contain identification information that enables the system to automatically identify which printer produced which chart. The color measuring device reads both the color data and the identification information from the chart itself, allowing the system to self-associate the measurement results with the correct printer without requiring manual user intervention to track or identify each printer.
2Reliability
If manual identification and tracking of each printer is required for quality management, then printing quality can be monitored, but operation complexity increases significantly
Solution Approach 1:
The color chart serves as an intermediary carrier that embeds identification information directly onto the printed material. This intermediary element enables the automatic linking between the printer and its output by containing unique identifiers that the color measuring device can read, thereby simplifying the overall system operation while maintaining reliable quality management across multiple printers.
3Ease of operation
If automatic identification of printers is implemented through color charts, then user burden is reduced, but the color chart design becomes more complex
Solution Approach 1:
The identification information is merged directly into the color chart design, combining the functional elements (color patches for measurement) with the identification elements (unique codes or patterns) into a single integrated chart. This allows the chart to serve dual purposes: quality measurement and printer identification, reducing user burden while the added complexity is confined to the chart design rather than the operation system.

AI summary
A color chart (CC) is for evaluating printing quality of an image forming apparatus (10). The color chart (CC) includes identification information and a color evaluation patch (CP). The identification information is on an image forming apparatus (10) on which evaluation of printing quality is to be performed. The color evaluation patch (CP) includes a plurality of color patches for performing evaluation of printing quality on the image forming apparatus (10) indicated by the identification information.
