Resin Powder Inkjet Image Forming to Prevent Ink Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming methods using pretreating agents result in residual traces and ink bleeding, which affect image quality and durability.
Innovation Solution
Applying a resin powder followed by a water-based ink using an inkjet method, and then fixing them with heat to form images, where the ink thickens or aggregates upon contact with the resin powder, eliminating the need for pretreating agents and preventing ink bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a pretreating agent is applied to prevent ink bleeding, then ink bleeding is prevented, but pretreating agent residues remain on the image
Solution Approach 1:
The invention extracts and eliminates the pretreating agent from the system by replacing it with resin powder that serves the same function of preventing ink bleeding without leaving harmful residues. The resin powder is applied directly to the object and reacts with the ink to achieve the desired effect without requiring a separate pretreating agent layer.
Solution Approach 2:
The invention changes the chemical parameters of the ink by reacting it with resin powder, transforming the ink's properties to prevent bleeding. The resin powder modifies the ink's behavior through chemical interaction, changing its adhesion and flow characteristics to eliminate bleeding issues without requiring pretreating agents.
2Object-affected harmful factors
If a pretreating agent is used to improve image quality, then ink bleeding is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The invention merges the functions of the pretreating agent and the ink application into a single step. The resin powder is applied in advance, and when the ink is applied, it automatically reacts with the resin powder to prevent bleeding, eliminating the need for separate pretreating and printing steps.
Solution Approach 2:
The resin powder is applied in advance to the object before ink application, preparing the surface to prevent ink bleeding. This preliminary action simplifies the overall process by pre-configuring the surface properties needed for bleed prevention, eliminating the need for complex multi-step pretreating procedures.
3Ease of manufacture
If conventional inkjet printing is used, then image forming is simple, but ink bleeding occurs reducing image quality
Solution Approach 1:
The resin powder acts as an intermediary between the ink and the object surface. It mediates the interaction by providing a reactive layer that controls ink behavior, preventing bleeding while maintaining the simplicity of the inkjet printing process. The resin powder facilitates proper ink adhesion and distribution without requiring complex printing parameters.

AI summary
An image forming method includes: applying a resin powder to a first area of an object to be subjected to image forming; applying a water-based ink comprising pigments to a second area of the object by an inkjet method to form an image, the first area and the second area at least partially overlapping each other; and heating the first area and the second area to fix the resin powder and the water-based ink to the object. By contact with the resin powder, the water-based ink either thickens, or causes an aggregation of the pigments.
