Color Adjustment Profiles for Multi-Printer Sample Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color adjustment techniques for printers require significant time and labor for color sample matching, especially when multiple printers are involved, necessitating the creation and circulation of print samples for each site, which is inefficient.
Innovation Solution
A color adjustment system that includes a first registration unit for job data, a second registration unit for color sample data, a print control for printing, a reading control for acquiring read image data, and a generation unit for creating an input profile to facilitate color matching across multiple printers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color sample matching is performed for each printer at each site using conventional methods, then color accuracy for individual printers is improved, but time and labor consumption increases significantly
Solution Approach 1:
The invention uses read image data from a reference printed matter as a digital copy to represent the actual printer output characteristics. Instead of requiring physical print samples to be circulated, the system creates virtual copies of printer responses through digital image reading, enabling remote color profile generation without physical sample exchange between sites and printers
Solution Approach 2:
The invention introduces a central management server as an intermediary that coordinates between multiple printers and sites. The server collects read image data, manages reference printed matters, and distributes color profiles, eliminating the need for direct interaction and physical sample circulation between each printer operator and reference materials
2Stability of the object's composition
If print samples are circulated among multiple sites for color matching, then color consistency across printers is improved, but operational complexity and work requirements increase
Solution Approach 1:
The reading apparatus is designed to serve multiple functions: it can read both the reference printed matter for color profile generation and the actual printed outputs for quality verification. This multi-functionality eliminates the need for separate reference sample circulation while maintaining color consistency across different printers and sites
Solution Approach 2:
The system replaces physical print sample circulation with digital image data exchange. Read images of the reference printed matter are transmitted electronically to the central server, which processes them to generate color profiles distributed to all sites, eliminating the logistical complexity of physical sample management
3Manufacturing precision
If color sample matching is performed individually for each job data, then color accuracy for specific jobs is improved, but processing efficiency decreases
Solution Approach 1:
The system performs preliminary color profile generation by reading the reference printed matter once and creating a universal color profile in advance. This pre-generated profile is then applied to multiple job data items without requiring repeated read operations, enabling efficient batch processing while maintaining color accuracy across all jobs
Solution Approach 2:
The invention combines multiple color matching operations into a single unified process. Instead of performing separate color sample matching for each job data item, the system merges them under a single color profile generated from one reference printed matter reading, significantly improving processing efficiency while maintaining consistent color accuracy
