Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If structural color ink is used for printing, then the print image exhibits angle-dependent color changes due to optical phenomena, but it becomes extremely difficult for users to visualize how the print image will look before printing
Solution Approach 1:
The patent creates a copy of the print image with angle-dependent color changes simulated on a display device. The display shows multiple preview images corresponding to different angles of visual recognition, allowing users to visualize the angle-dependent color changes before actual printing. This copy enables users to understand the appearance of structural color ink prints without needing to physically print and examine them at various angles.
Solution Approach 2:
The patent changes the parameter of angle of visual recognition to demonstrate color changes. By displaying multiple preview images corresponding to different angles (e.g., front view, side view, angled views), the system simulates how the structural color ink appears at different viewing angles. This parameter change approach allows users to visualize the color variation without physical printing.
2Measurement precision
If multiple preview images corresponding to different angles are displayed, then users can accurately preview color changes, but the device complexity increases due to color conversion processing requirements
Solution Approach 1:
The patent introduces color conversion processing as an intermediary step between the original print image data and the display output. The color conversion unit converts the print image data into color space appropriate for displaying angle-dependent color changes. This intermediary processing enables accurate preview generation by transforming the structural color ink characteristics into displayable formats for multiple angles.
Solution Approach 2:
The display control device performs multiple functions through a unified system: it displays preview images, processes color conversion for structural color ink, and presents angle-dependent visual information. The same device handles both the original image display and the angle-dependent color simulation, reducing the need for separate specialized equipment while maintaining high preview accuracy.

AI summary
A display control device controls a display screen for displaying a preview of a print image to be printed on a recording medium by using an ink. The print image is printed using, as the ink, a structural color ink of which a color changes due to an optical phenomenon caused by a structure, and a color of the print image changes depending on an angle of visual recognition. The display control device includes: a processor. In a case where the print image is visually recognized at different angles, the processor is configured to display, on the display screen, a plurality of preview images corresponding to the angles by performing color conversion processing corresponding to the structural color ink.
