Porous Printing Foundation for Ink Blurring Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing methods using solvent-based inks result in ink blurring during the production of ceramic electronic components, which cannot be effectively prevented by the gelling reaction with PVA layers when using water-based inks.
Innovation Solution
A printing foundation with a support having a porous structure and a functional layer containing resin particles covered by polyvinyl alcohol (PVA) that absorbs the solvent of the ink, reducing or preventing ink blurring for both water-based and solvent-based inks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a PVA layer is applied to suppress ink blurring when using water-based ink, then ink blurring is suppressed for water-based ink, but ink blurring occurs when using solvent-based ink
Solution Approach 1:
The functional layer is designed to work with both water-based and solvent-based inks by incorporating resin particles with solvent-absorbing properties that complement the PVA layer's water-based ink gelling effect. This multi-functional design allows the same printing foundation to suppress ink blurring regardless of ink type, achieving universality across different printing applications.
Solution Approach 2:
The functional layer combines PVA-coated resin particles with a porous support structure to create a composite material that addresses both water-based and solvent-based ink challenges. The PVA component handles water-based ink through gelling reaction, while the porous structure and resin particles manage solvent-based ink through absorption and capillary action, creating a synergistic effect.
2Manufacturing precision
If a functional layer with resin particles covered by PVA is used to absorb solvent, then ink blurring is reduced for both water-based and solvent-based inks, but the structure becomes more complex
Solution Approach 1:
The support is designed with a porous structure that provides solvent absorption capacity and capillary action to prevent ink blurring. This porous architecture allows the functional layer to manage solvent-based inks effectively while maintaining a relatively simple overall structure that does not require multiple separate components.
Solution Approach 2:
The functional layer acts as an intermediary between the ink and the porous support, with resin particles covered by PVA serving as the active medium that absorbs solvent and works synergistically with the porous structure to prevent ink blurring, thereby simplifying the overall system design.
