Printing System Color Accuracy via Server Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems fail to ensure consistent color reproduction across different printers, leading to undesirable color output in printed materials due to lack of effective color management.
Innovation Solution
A network-based printing system that includes a terminal device, multiple printers, a first server for selecting printers based on round-trip accuracy, and a second server storing color conversion profiles, which calculates and converts color values to ensure accurate color reproduction by determining the best printer for printing based on target color information and color reproduction characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If any printer is selected from the plurality of printers without color management, then the system can operate with simple selection logic, but the color reproduction accuracy varies and desired color characteristics cannot be obtained
Solution Approach 1:
The system performs preliminary color management by obtaining color conversion profiles for each printer in advance and storing them in a database. When a printing command is received, the server calculates round-trip accuracy using these pre-stored profiles, enabling quick selection of the most suitable printer without real-time color measurement, thus resolving the contradiction between accuracy and complexity
Solution Approach 2:
The invention introduces an intermediary color management server that acts as a mediator between the terminal device and multiple printers. This server calculates round-trip accuracy using color conversion profiles and selects the most appropriate printer, thereby achieving accurate color reproduction without requiring complex color management logic in each printer or terminal device
2Measurement precision
If color conversion profiles are obtained and round-trip accuracy is calculated for each printer, then color reproduction accuracy is improved, but processing time and computational load increase
Solution Approach 1:
Color conversion profiles for each printer are obtained and stored in advance in a database before actual printing operations. This preliminary preparation eliminates the need for real-time profile acquisition during printing, significantly reducing processing time while maintaining color accuracy through pre-calculated round-trip accuracy values
Solution Approach 2:
The system extracts and stores essential color conversion profile data in advance, separating the time-consuming color characterization process from the actual printing workflow. By extracting color profiles beforehand and storing them for rapid retrieval, the system achieves both color accuracy and efficient processing

AI summary
A printing system includes a terminal device, a plurality of printers, a first server, and a second server. The first server calculates a round-trip accuracy of each printer using a color conversion profile supplied from the second server with respect to target color information included in a printing command provided from the terminal device, and selects one or more printers among the plurality of printers according to the round-trip accuracy to cause the printers to execute printing.
