Solution Overview
Problem
The production of personal information media, such as ID cards, faces challenges in ensuring the accurate combination of personal information in colored and structural color regions, which are printed separately, leading to risks of incorrect combinations.
Innovation Solution
A printing system with a control apparatus that manages the printing of personal information items using both pigment and structural color materials, ensuring accurate combinations by linking identification information across different printing units, allowing for verification and precise placement of personal information items on a media sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If personal information in colored region and structural color region are printed in separate steps, then production process can be simplified and materials can be optimized, but accuracy of combining personal information items deteriorates
Solution Approach 1:
The system performs preliminary actions by printing identification information in the colored region first, then uses this identification information to guide the subsequent printing in the structural color region. The control apparatus stores correspondence between identification information and personal information items, and automatically retrieves and prints the correct matching personal information in the second printing step, ensuring accurate combination without manual intervention.
Solution Approach 2:
The system implements feedback by reading the identification information that was printed in the first step, using this read information to determine which personal information items should be printed next, and verifying that the correct items are printed. This closed-loop feedback mechanism ensures that the personal information in both regions corresponds to the same person, resolving the accuracy issue while maintaining separate printing steps.
2Adaptability or versatility
If separate printing steps are used for colored and structural color regions, then printing flexibility and material optimization are improved, but risk of incorrect personal information combination increases
Solution Approach 1:
The system introduces identification information as an intermediary element that links the colored region printing and structural color region printing. This identification information acts as a mediator that carries the correspondence relationship between the two printing steps, enabling flexible separate printing while ensuring reliable combination through the mediating identification data.
Solution Approach 2:
The system replaces manual verification and matching mechanisms with an automated information processing system. The control apparatus automatically reads identification information, retrieves corresponding personal information from storage, and prints the correct items without human intervention, substituting mechanical/manual operations with automated digital processing to ensure reliability.

AI summary
A printing system includes a first printing unit that performs printing using a material that exhibits structural color, based on first data, a second printing unit that performs printing using a material that includes pigment, based on second data, and a control apparatus that outputs the first data and the second data; the first data causes the first printing unit to print the first personal information items of a first information group in respective regions, and an item of identification information linked to the first information group; and the second data causes the second printing unit to print the second personal information items of a second information group linked to the item of identification information on the corresponding respective regions on which the first personal information items corresponding to the respective second personal information items have been printed.
