Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orange ink compositions for sublimation transfer face challenges in achieving stable printing due to gas generation from disperse dyes, leading to instability and poor color reproducibility.
Innovation Solution
An ink set comprising an orange ink composition with a specific disperse dye, along with yellow, magenta, and cyan ink compositions, containing specific disperse dyes, which reduces gas generation and enhances color reproducibility by using a combination of disperse dyes like C.I. disperse orange 25, C.I. disperse violet 28, C.I. disperse blue 72, C.I. disperse yellow 54, C.I. disperse red 60, and C.I. disperse blue 359, and includes water, water-soluble organic solvents, and surfactants to improve stability and viscosity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disperse dyes are used in orange ink composition for sublimation transfer, then color reproduction is achieved, but gas is generated leading to poor printing stability
Solution Approach 1:
The patent changes the chemical structure parameters of the disperse dye by specifying precise molecular weight ranges (150-300 for the parent compound, 200-400 for the coupled compound) and chemical composition ratios. This parameter optimization reduces gas generation during sublimation while maintaining color reproduction, thereby improving printing stability without sacrificing color quality.
2Reliability
If single-color ink compositions are used, then manufacturing is simple, but color reproducibility and stability are poor
Solution Approach 1:
The patent combines multiple disperse dyes with different molecular weights and chemical structures into a single orange ink composition. This merging of complementary dye components enhances color reproducibility and printing stability while maintaining manageable composition complexity through systematic selection of dye parameters.
3Reliability
If disperse dyes with specific structures are used to reduce gas generation, then printing stability improves, but dye dispersion and color development may be affected
Solution Approach 1:
The patent creates a composite dye system combining multiple disperse dye compounds with complementary properties. This composite approach ensures that while individual dyes have optimized structures for reduced gas generation, the combination maintains excellent dispersion uniformity and color development through synergistic effects of the different dye components.
