Solution Overview
Problem
Existing recording materials for dye sublimation printing suffer from transport difficulties in printers, leading to image offset and quality deterioration due to friction with transport rollers, despite having properties like low thermal conductivity, heat resistance, and dimensional stability.
Innovation Solution
A recording material with a base paper having a rear-side synthetic resin layer with an elastic modulus of at least 0.8 GPa, a dye-receiving layer on the front side, a plastic film between the base paper and dye-receiving layer, and optionally a barrier layer, which enhances transport properties and reduces friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the recording material uses a conventional structure with low elastic modulus, then it achieves good compressibility and contact with thermal head, but it causes friction with transport rollers leading to offset and positioning errors
Solution Approach 1:
The patent applies parameter changes by modifying the elastic modulus of the synthetic resin layer to at least 0.8 GPa, transforming the material from too soft (causing friction) to optimally rigid (reducing friction while maintaining contact). This parameter adjustment resolves the contradiction between positioning precision and friction generation.
Solution Approach 2:
The patent uses composite materials by combining base paper with a synthetic resin layer having specific elastic properties. This composite structure provides both the necessary mechanical strength to reduce friction and the compliance to maintain contact with the thermal head, resolving the contradiction between positioning precision and friction.
2Ease of operation
If the recording material has high compressibility, then it ensures good contact between thermal head and recording material, but it leads to transport difficulties and offset in successive printing passes
Solution Approach 1:
The patent changes the elastic modulus parameter to at least 0.8 GPa, which optimizes the balance between compressibility for contact quality and rigidity for transport stability. This parameter adjustment ensures good thermal contact while preventing offset during successive printing passes.
Solution Approach 2:
The patent applies dynamics by making the synthetic resin layer's mechanical properties adaptable - sufficiently compliant during thermal contact to ensure quality printing, yet sufficiently rigid during transport to maintain positioning precision across multiple passes.
3Manufacturing precision
If the recording material uses smooth surface, then it reduces friction with transport rollers, but it compromises the connection quality needed for precise positioning
Solution Approach 1:
The patent changes the elastic modulus parameter of the synthetic resin layer to at least 0.8 GPa, which fundamentally alters the friction characteristics. This parameter change reduces friction with transport rollers while maintaining sufficient connection quality for precise positioning through the material's optimized mechanical compliance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material achieves significantly improved printing quality by minimizing image offset and ensuring precise alignment with print heads, maintaining image quality through successive printing processes.
Implementation Method 1
The local heat causes the dye to sublimate from the donor layer of an ink ribbon or ink sheet in contact with the recording material to be printed and diffuse into the dye-receiving layer of the recording material
Implementation Method 2
The local heat causes the dye to sublimate from the donor layer
Implementation Method 3
diffuse into the dye-receiving layer of the recording material
Implementation Method 4
friction occurs during the transport of the recording material in the printer, which means that optimal positioning of the recording materials relative to the print head cannot be guaranteed
