Security Ink Color Matching for Visible Anti-Counterfeit Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may fail to recognize optically variable color-changing security features in security articles due to unawareness of their presence, limiting the effectiveness of these features in preventing forgery or counterfeiting.
Innovation Solution
Incorporation of a dynamic security feature, such as a magnetically aligned magnetic color-shifting ink, with a static security feature within a threshold proximity, creating a metameric effect that enhances visibility and recognition through a rolling bar effect or three-dimensional illusion, thereby drawing attention to the static feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optically variable color-changing ink is used to print security features, then the security article becomes more difficult to forge, but users may fail to recognize the security feature due to unawareness of its presence
Solution Approach 1:
The patent employs optically variable color-changing ink that exhibits different colors when viewed from different angles. This color-shifting property creates a visually striking effect that naturally draws user attention. The ink contains particles that reflect light differently based on viewing angle, producing a dynamic color change that is difficult to replicate and immediately noticeable to users, thereby resolving the contradiction between security effectiveness and user recognition.
2Ease of operation
If a dynamic security feature with color-shifting ink is incorporated, then the security article becomes more visually striking and attention-grabbing, but the device complexity and manufacturing process become more complex
Solution Approach 1:
The patent combines multiple security features into a single integrated printing process. The optically variable ink is applied directly to the substrate in the same printing operation as other security features, eliminating the need for separate application steps. This merging of functions reduces overall process complexity while maintaining the visual striking effect and user inspectability of the dynamic security feature.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The metameric effect increases the likelihood of users inspecting the static security feature, reducing the chances of fraudulent passing off security articles as genuine by improving color contrast and recognition.
