Multi-layer Security Document with Register Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security and value documents lack secure, easily recognizable, and forgery-proof individualizing features that can be assigned to users or objects, particularly in colored representations with enhanced visual appeal and information content.
Innovation Solution
A multi-layer document structure with a first pattern formed by regular image elements on a document layer and a second pattern created by adding or removing image elements above the first pattern, allowing for individualizing information to be generated through a combination of visible and invisible elements, ensuring secure authentication by requiring delamination for manipulation, which is difficult to achieve without detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individualizing information is stored by printing on document layers, then the document can be personalized and assigned to specific users or objects, but the production process becomes complex and requires precise registration of multiple print extracts across spaced-apart planes
Solution Approach 1:
The individualizing information is divided into multiple print extracts that are distributed across at least two spaced-apart planes (document layers). Each plane contains a portion of the overall information, and the complete information is revealed only when all planes are viewed together in register. This segmentation enables personalization while distributing the production complexity across multiple layers rather than requiring a single complex printing process.
Solution Approach 2:
The patent transitions from two-dimensional printing on a single layer to a multi-dimensional structure with print extracts arranged in at least two spaced-apart planes. This adds a vertical dimension (depth between layers) to the information storage, allowing the document to convey individualizing information through the spatial arrangement of printed elements across multiple planes rather than requiring complex registration processes in a single plane.
2Reliability
If multiple print extracts are arranged in spaced-apart planes to create individualizing information, then security against forgery is improved, but the manufacturing precision requirements increase due to the need for precise registration
Solution Approach 1:
By segmenting the individualizing information into multiple print extracts across spaced-apart planes, the patent enhances security against forgery. The complete information cannot be replicated by copying a single layer, as the spatial relationship and register between multiple planes must be precisely maintained. This segmentation creates a more secure document while the manufacturing precision requirement is managed through the distributed architecture.
Solution Approach 2:
The patent employs a nested structure where multiple document layers containing print extracts are stacked and laminated together. The print extracts in different planes are nested within the multi-layer document structure, with each layer containing a portion of the individualizing information. This nesting approach enhances security by requiring delamination to access and manipulate the information, while the registration precision is maintained through the laminated structure that holds layers in fixed spatial relationships.
3Reliability
If the document is designed as a multi-layer laminated structure with print extracts in different planes, then manipulation and forgery become difficult, but the production process becomes more complex and time-consuming
Solution Approach 1:
The patent segments the document into multiple laminated layers, each containing specific print extracts. This segmentation enhances resistance to manipulation by requiring delamination to access or alter individualizing information. The distributed architecture across layers makes forgery more difficult while the production process, though more complex, can be optimized through standardized lamination procedures.
Solution Approach 2:
The multi-layer laminated structure nests multiple document layers together in a fixed spatial arrangement. This nesting provides security by making manipulation difficult without detection, as the layers must be precisely aligned. The production efficiency is maintained through the use of standardized lamination processes that can efficiently combine multiple layers with pre-positioned print extracts, despite the increased number of production steps.
4Loss of information
If individualizing information is created by combining first and second patterns with image elements in register, then the visual appeal and information content are enhanced, but the complexity of creating and registering the patterns increases
Solution Approach 1:
The patent segments the individualizing information into two distinct patterns: a first pattern with first image elements and a second pattern with second image elements. These patterns are created separately and then combined in register to form the complete individualizing information. This segmentation allows for enhanced information content and visual appeal while managing the complexity by dividing the pattern creation process into manageable stages.
Solution Approach 2:
The patent adds a vertical dimension to the pattern arrangement by placing the first and second patterns in different spaced-apart planes. This dimensional addition enhances the visual appeal and information content by creating a multi-level pattern structure. The registration complexity is managed by maintaining precise spatial relationships between the patterns across the vertical dimension, allowing the enhanced information content to be achieved through structured three-dimensional arrangement rather than overly complex two-dimensional registration.

AI summary
In order to generate a novel security feature for documents of value and/or security documents, a document of value and/or a security document 10 having preferably at least one document layer 13, 14 is created. A first pattern formed from first image elements 14.1, 14.2, 14.3, 14.4, 14.5 is located in one or more first planes. Furthermore, a second pattern, which is formed from second image elements 13.1, 13.5 and is arranged in register in relation to the first image elements 14.1, 14.2, 14.3, 14.4, 14.5 of the first pattern, is located in one or more second planes. The second image elements 13.1 are located in front of the first image elements 14.1, 14.2, 14.3, 14.4, as seen from a viewing side of the document 10. A second image element 13.1 is arranged in each case only over some of the first image elements 14.1, 14.2, 14.3, 14.4.
