Recording Apparatus Uniform Color via Foaming Control Liquid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming three-dimensional images using foaming particles on a recording medium result in uneven coloration due to differences in the height and surface area of the convex structures formed, leading to color differences across the image.
Innovation Solution
A recording apparatus that applies a foaming control liquid and a colored liquid to a recording medium, adjusting the application amounts based on data to ensure consistent color across regions with varying foaming degrees, thereby controlling the foaming degree and surface area of the foaming particles to maintain even coloration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a foaming control liquid is applied to control the foaming degree of foaming particles, then the three-dimensional structure is formed, but color differences occur between regions with different foaming degrees
Solution Approach 1:
The patent applies different application amounts of colored liquid to different regions based on the foaming control liquid application amount. Regions with higher foaming control liquid application (higher foaming degree) receive more colored liquid, while regions with lower foaming control liquid application receive less colored liquid. This local adjustment of colored liquid application compensates for the surface area differences caused by varying foaming degrees, ensuring uniform color appearance across the three-dimensional image.
2Manufacturing precision
If the application amount of colored liquid is increased to compensate for larger surface area in high foaming regions, then color uniformity is improved, but the complexity of controlling application amounts increases
Solution Approach 1:
The patent uses the application amount of foaming control liquid as a reference signal to determine the application amount of colored liquid. The control unit calculates the colored liquid application amount based on the foaming control liquid application amount data, creating a feedback mechanism where the first liquid's application pattern guides the second liquid's application. This interlinked control approach simplifies the overall system by using existing control data rather than requiring independent complex control for each liquid.

Function Achieved in This Case
This approach prevents color differences caused by the foaming degree, ensuring an evenly colored three-dimensional image is recorded by adjusting the application amounts of the colored liquids in accordance with the foaming control liquid's effect on the foaming particles.

AI summary
A recording apparatus controls a color difference caused by a degree of foaming of foaming particles in a case of forming a recording product including a convex structure that is formed by causing the foaming particles to foam, by determining application amounts of colored liquids so that a larger amount is applied to a region that is caused to foam in a larger degree even when the colored liquids indicate the same color.
