Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inkjet printing technologies face challenges when printing on large format substrates such as wall coverings and banners, particularly in achieving durable, high-quality images with good mechanical strength and resistance to abrasion, while avoiding the use of harmful materials like PVC and ensuring compliance with industry standards.
Innovation Solution
A printable media comprising a supporting substrate with an image receiving layer coated on one side, containing pigment fillers, polymeric binders, and optical density enhancement agents, designed to receive inkjet inks and provide excellent image quality, durability, and compliance with standards like ASTM and CCC-W, with optional textured surfaces for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional inkjet printing is used on large format substrates, then printing capability is achieved, but image durability and abrasion resistance are insufficient
Solution Approach 1:
The patent applies composite materials by formulating an image receiving layer containing multiple components including polymeric binders, pigment fillers, and optical density enhancement agents. This composite structure provides both durability and print quality, resolving the contradiction between image durability and printing quality.
Solution Approach 2:
The patent employs parameter changes by optimizing the composition ratios and physical properties of the image receiving layer materials. By adjusting parameters such as polymer content, particle size distribution, and layer thickness, the patent achieves both high image durability and excellent print quality simultaneously.
2Strength
If PVC materials are used for wall coverings, then mechanical strength is improved, but harmful effects are introduced
Solution Approach 1:
The patent applies the extraction principle by removing harmful PVC materials from the composition entirely and replacing them with safe, effective alternatives such as polymeric binders and pigment fillers. This eliminates harmful effects while maintaining the necessary mechanical strength through the optimized composite formulation.
Solution Approach 2:
The patent uses parameter changes by modifying the material composition to exclude harmful substances while adjusting the physical and chemical parameters of alternative materials to achieve equivalent or superior mechanical strength performance.
3Reliability
If the image receiving layer is made thicker to improve durability, then abrasion resistance increases, but manufacturing complexity increases
Solution Approach 1:
The patent applies local quality by concentrating functional ingredients strategically within the image receiving layer rather than uniformly distributing them throughout a thick structure. This allows for enhanced abrasion resistance through optimized local composition rather than increased overall thickness, simplifying the manufacturing process.
Solution Approach 2:
The patent uses composite materials to achieve high abrasion resistance in a optimized thickness by combining multiple functional components with complementary properties, avoiding the need for excessive layer thickness while maintaining durability.
