Color Adjustment System Using Identification Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color adjustment techniques for commercial printing struggle to efficiently and accurately adjust colors in printed materials, particularly in systems where independent execution of printing and reading processes is not feasible.
Innovation Solution
A color adjustment system that includes circuitry to register job data and color sample data, generates an input profile based on the color sample data and the document file, and uses this profile to print an image with an identification code, allowing for independent analysis and adjustment of color settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If color adjustment is performed using traditional color sample matching with integrated printing and reading processes, then color accuracy can be maintained, but operational flexibility and efficiency are reduced due to dependency between printing and reading processes
Solution Approach 1:
The patent divides the color adjustment process into independent modules: a printing apparatus that generates printed matter with identification codes, and a reading apparatus that reads the printed matter and generates color data. This segmentation allows each apparatus to function independently, improving operational flexibility while maintaining color adjustment efficiency through automated data exchange via the identification codes.
2Reliability
If printing and reading processes are integrated, then color matching can be performed, but the system becomes more complex and less adaptable to different scenarios
Solution Approach 1:
The patent introduces an identification code as an intermediary element between the printing apparatus and reading apparatus. This code carries job data that enables the reading apparatus to accurately identify and process the corresponding printed matter, ensuring color matching accuracy while keeping the overall system structure simple and modular rather than tightly integrated.
3Measurement precision
If traditional color sample matching is used, then color accuracy can be achieved, but the process is time-consuming and less automated
Solution Approach 1:
The patent implements self-service automation where the printing apparatus automatically embeds identification codes containing job data into the printed matter, and the reading apparatus automatically reads these codes to retrieve corresponding color sample data. This eliminates manual intervention in color matching, achieving both high color accuracy and reduced processing time through automated data exchange.

AI summary
A color adjustment system includes circuitry to register in a memory job data for instructing printing of an image based on a document file, register color sample data in the memory in association with the job data, cause a printing apparatus to print, using an input profile corresponding to the job data, the image based on the document file indicated by the job data to output a first printed matter including an identification code for identifying the job data, acquire first read image data obtained by a reading apparatus reading the first printed matter, analyze the identification code to specify a particular job data the first printed matter corresponds to, and newly generate another input profile corresponding to the particular job data based on the color sample data, the input profile, and the document file corresponding to the particular job data indicated by the identification code.
