Solution Overview

Problem

Existing security and valuable products, such as documents, face challenges in decentralized individualization, particularly in producing multicolored representations of individualization data that are secure against manipulation and easy to authenticate.

Innovation Solution

A security product with a non-individualizing security print and an individualizing security feature printed in the same plane on the outer sides, covered by a structured protective layer, allowing for multicolored representation and secure authentication through an intimate connection between the inks, making manipulation visible and difficult.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individualization data are printed on inner layers of the document, then manipulation resistance is improved, but multicolored reproduction capability deteriorates

Engineering Contradiction:
Improvemanipulation resistanceVSAvoidmulticolored reproduction capability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of printing individualization data on inner layers as conventionally done, the patent inverts the approach by printing on outer layers. This allows multicolored reproduction while maintaining security through a different mechanism (the connection between security print and individualization data).

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent merges the security print and individualization data into a single integrated printing process on the same outer layer. This combination ensures that any manipulation of the individualization data necessarily affects the security print as well, providing manipulation resistance without requiring inner layer placement.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If individualization is performed in a centralized production facility, then manufacturing control is improved, but processing speed and decentralization capability deteriorate

Engineering Contradiction:
Improvemanufacturing controlVSAvoidprocessing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent segments the production process into two parts: security print (centralized control) and individualization data (decentralized addition). This allows the security-critical aspects to be controlled centrally while enabling fast, decentralized individualization at issuing points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The security print is applied in advance during centralized production, preparing the document body for subsequent decentralized individualization. This preliminary action enables rapid personalization at issuing points without compromising security.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a laser beam process is used for individualization, then manipulation resistance is improved, but color reproduction capability deteriorates

Engineering Contradiction:
Improvemanipulation resistanceVSAvoidcolor reproduction capability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the mechanical laser beam process with a printing process. This substitution enables multicolored reproduction of individualization data while maintaining manipulation resistance through the integrated design of the security print and individualization data on the same layer.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A value or security product (100) is created for the decentralised individualisation of value or security products (100) with a multi-coloured individualising security characteristic (200) that is secured against tampering. The value or security product (100) is formed by a product body (150) having two outer sides (125). Same has at least one non-individualising security print (128) as well as the at least one individualising security characteristic (200). The at least one non-individualising security print (128) and the at least one individualising security characteristic (200) are printed overlapping one another at least on one of the outer sides (125) of the product body (150) in the same printing plane (126).
