Security Label Simultaneous Code Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security labels with hidden codes are complex and expensive to produce, often requiring multi-layer designs or rub-off fields, which complicate integration and increase costs.
Innovation Solution
A security label with a four-layer structure incorporating complementary release lacquer layers and color layers, where a visible first security code and a hidden second security code are printed simultaneously in the same layer, allowing the hidden code to be revealed only upon opening, with the second code remaining on the product and the first code being visible before opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional multi-layer security label with void effect is used, then the label provides basic security features, but integrating hidden codes requires additional complex multi-layer designs or rub-off fields that increase production costs
Solution Approach 1:
The patent combines the hidden code functionality with the existing four-layer security label structure (first separating lacquer layer, first color layer, second separating lacquer layer, second color layer) by printing both visible and hidden codes in the same layer during a single printing step, eliminating the need for separate rub-off fields or additional multi-layer designs
Solution Approach 2:
The same layer structure serves multiple functions: it provides the void effect security feature, contains both visible and hidden codes, and enables tamper evidence, all within the conventional four-layer configuration without requiring additional specialized components
2Productivity
If separate printing steps are used for visible and hidden codes in different layers, then code security is maintained, but production time and complexity increase
Solution Approach 1:
Both the visible code and hidden code are printed simultaneously in the same layer during a single printing step, consolidating what would traditionally require separate printing operations into one efficient process
Solution Approach 2:
The printing process is designed to deposit both visible and hidden codes in advance during the same operation, with the hidden code positioned to remain on the product after label removal, eliminating the need for subsequent separate printing steps
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
This approach simplifies the production process, reduces costs, and allows for easy verification of the label's opening status by changing the refraction behavior of light when the tab is pressed back onto the product, while maintaining the security of the hidden code.
Implementation Method 1
the refraction behavior of the light changes as a result

AI summary
The invention relates to a security label with a multi-layered tamper-evident feature comprising a layer structure with a first and second ink layer (105, 205, 305 and 106, 206, 306) and a first and second release varnish layer (104, 204, 304 and 108, 208, 308), wherein at least a first security code (102, 202, 302) is readable on the closed security label (100, 200, 300), a second security code (107, 207, 307) is only readable after opening the tamper-evident feature, and the second security code (107, 207, 307) is located between the first or the second release varnish layer (104, 204, 304 or 108, 208, 308) and the second ink layer (106, 206, 306) is arranged and the first security code (102, 202, 302) and second security code (107, 207, 307) are printable simultaneously.
