Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Structural color inks, which change color due to optical phenomena, pose challenges in visualizing the final print image appearance before printing, especially when combined with different backgrounds, as existing display control devices cannot accurately preview the color changes caused by background interactions.
Innovation Solution
A display control device and method that includes a processor for displaying a preview image subjected to color conversion processing, accounting for both the structural color ink's angle-dependent and background-dependent color changes, allowing users to select and visualize how the print image will appear with various backgrounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If structural color ink is used for printing, then the print image can exhibit unique optical color effects, but it becomes extremely difficult for users to visualize how the print image will look before printing
Solution Approach 1:
The patent creates a virtual copy of the print image on a display device that replicates the optical properties of structural color ink. The preview image is generated by applying the same structural color effects to a digital representation, allowing users to visualize the final appearance before actual printing occurs.
Solution Approach 2:
The patent implements color conversion processing that simulates the optical phenomena (refraction, interference, diffraction, scattering) of structural color ink on the display screen. This allows the preview image to change color in response to viewing angles and background conditions, just like the actual printed image will do.
2Adaptability or versatility
If structural color ink is used, then the color development is due to optical phenomena rather than pigment reflection, but the color changes depending on the background making preview difficult
Solution Approach 1:
The patent incorporates background information into the preview generation process. The display control device receives background data and uses it to calculate the appropriate color conversion for the preview image, providing feedback about how the structural color ink will interact with the actual background during printing.
Solution Approach 2:
The patent dynamically adjusts color conversion parameters based on the background conditions. Different background colors and types require different color conversion calculations to accurately represent how the structural color ink will appear, allowing the system to adapt the preview to match various printing scenarios.
3Device complexity
If simple image switching is used for preview, then the display control is simple, but it cannot accurately represent the background-dependent color changes of structural color ink
Solution Approach 1:
The patent replaces simple mechanical image switching with a computational color conversion system. Instead of physically switching between pre-defined images, the system calculates and generates preview images in real-time by applying optical physics-based color conversion algorithms to the print image data.
