Printer Process Color Composition with Substrate Colorant for Gamut Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing systems face limitations in printable gamut due to the use of white ink/toner on colored or black substrates, reducing the amount of available ink/toner for color composition and leading to excessive energy consumption, waste, and environmental impact.
Innovation Solution
Incorporating the substrate colorant into the color management process, allowing for tailored combinations with printer colorants using distribution functions to extend the printable gamut, reduce ink/toner usage, and optimize energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If white ink/toner is used to cover colored or black substrates, then a uniform printing surface is achieved, but the printable gamut is significantly reduced
Solution Approach 1:
The patent applies local quality by selectively covering only certain areas of the substrate with white ink/toner based on the specific design requirements, rather than uniformly covering the entire substrate. This allows different regions to have different properties: areas requiring substrate color remain uncovered, while areas requiring additional colorants are selectively covered with white ink/toner.
Solution Approach 2:
The patent implements dynamics by making the white ink/toner coverage variable and adaptive to each specific print job and substrate combination. The system dynamically adjusts the amount and distribution of white ink/toner based on real-time assessments of substrate color, desired output colors, and design requirements, rather than using a fixed coverage approach.
2Ease of operation
If a fixed amount of base ink is used regardless of substrate color, then the printing process is simplified, but the printable gamut is significantly reduced
Solution Approach 1:
The patent implements dynamics by making the base ink amount variable and adaptive to each specific print job and substrate combination. The system dynamically adjusts the amount of base ink based on real-time assessments of substrate color, desired output colors, and design requirements, rather than using a fixed coverage approach.
Solution Approach 2:
The patent applies parameter changes by modifying the amount of base ink deposited based on substrate color characteristics. The system changes the ink deposition parameters dynamically, adjusting concentration and quantity based on the specific substrate being printed on, thereby optimizing the printable gamut for each case.
3Stability of the object's composition
If more base ink is deposited to compensate for substrate color variation, then color consistency is improved, but energy consumption and waste increase
Solution Approach 1:
The patent applies parameter changes by precisely controlling the amount of base ink deposited based on substrate color characteristics. Rather than using excessive ink to ensure coverage, the system adjusts ink deposition parameters to match the specific substrate properties, achieving color consistency with optimized ink usage and reduced energy consumption.
Solution Approach 2:
The patent implements feedback by using real-time assessments of substrate color and print results to dynamically adjust ink deposition. The system monitors the printing process and makes adjustments based on actual substrate characteristics and output quality, preventing both over-inking and under-inking, thereby optimizing energy consumption while maintaining color consistency.
4Manufacturing precision
If manual iterations and expert assessments are used to optimize ink amounts, then printing quality is improved, but time consumption and cost increase
Solution Approach 1:
The patent implements feedback by using real-time assessments of substrate color and print results to automatically adjust ink deposition parameters. The system incorporates automated color measurement and analysis, providing continuous feedback that enables precise optimization without manual intervention, thereby maintaining high printing quality while dramatically reducing time consumption.
Solution Approach 2:
The patent replaces manual mechanical processes (expert visual assessment and manual adjustment) with automated optical and computational systems. The system uses automated color measurement devices, digital image processing, and algorithms to assess substrate color and optimize ink deposition, substituting human expertise with automated technological systems that are faster and more consistent.

AI summary
In printing, the substrate colorant is used for the color management process of images or artwork, printed on white ink/toner covered areas. With the specific inclusion of the substrate colorant, which reduces the amount of white ink/toner printed, a significant extension of the printing color, for substrates with chromatic coloring, or the darkness, for black substrates, is possible.
