Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing scratch-off structures require multiple printing apparatuses, exposing valuable security content to human eyes and reducing overall security.
Innovation Solution
A system and method utilizing a single duplex printer to apply layers sequentially on both sides of a transparent substrate, including a primer, security ink, opaque background, corona treatment, release ink, and opaque cover image, ensuring the security information remains hidden until revealed by mechanical force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple printing apparatuses are used to produce scratch-off structures, then the production process can be completed, but the security content is exposed to human eyes during production
Solution Approach 1:
The patent combines multiple printing operations into a single printing apparatus by implementing a duplex printing system that can print on both sides of the substrate sequentially. This merging of functions eliminates the need for multiple separate printing apparatuses while maintaining security, as the substrate is handled continuously within one controlled environment and the security content remains obscured during the entire printing process.
Solution Approach 2:
The patent utilizes the third dimension (depth/layers) by implementing duplex printing that operates on both faces of the substrate. By printing on the opposite side of the substrate in sequence, the system maintains security coverage while completing all printing operations, effectively using spatial dimensionality to resolve the contradiction between security and device complexity.
2Ease of manufacture
If multiple printing apparatuses are used, then the scratch-off structure can be produced, but operational complexity increases
Solution Approach 1:
The patent merges multiple printing functions into a single duplex printing apparatus, consolidating what would require multiple separate devices into one integrated system. This reduces operational complexity by eliminating the coordination, material handling, and setup requirements between multiple apparatuses while maintaining complete production capability.
3Reliability
If a single duplex printer is used to apply layers sequentially, then security content remains hidden, but the printing process becomes more complex
Solution Approach 1:
The patent applies preliminary printing actions on one side of the substrate before proceeding to the other side. By completing all necessary printing operations on the first face while the security content remains covered, and then flipping to print on the second face, the system maintains security throughout the process while managing complexity through systematic sequencing.

AI summary
In one example of the disclosure, a substantially transparent substrate is provided at a printer. A primer layer is applied upon a first surface of the substrate. A security ink layer that includes security information is applied upon the primer layer. An opaque background ink layer is applied upon the security ink layer. A corona treatment is applied to a second surface, located on an opposite side of the substrate relative to the first surface. A release ink layer is applied upon the corona-treated second surface. An opaque cover image ink layer is applied upon the release ink layer.
