Document Code Merging for N-up Copy Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When documents containing codes are copied at an N-up setting, the reduced size of the document images leads to a significant reduction in the area available for printing other information, degrading its visibility.
Innovation Solution
An apparatus and method that create a single code with higher security level information from two documents, reducing their size and adding it to the documents, while deleting unnecessary information to maintain visibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If codes of original size are printed as they are to maintain decodability, then code security is preserved, but the area available for printing other information is considerably reduced
Solution Approach 1:
The patent merges multiple codes from different documents into a single composite code. By combining the code regions from multiple documents, the system creates one unified code that contains the essential security information from all source documents, thereby reducing the total code area while maintaining security requirements.
Solution Approach 2:
The patent extracts only the necessary security information from the original codes rather than reproducing the entire code structure. By taking out only the essential decoding elements and security-critical data, the system creates smaller codes that maintain decodability while occupying less space.
2Reliability
If multiple codes from different documents are included in one sheet, then security information is preserved, but the visibility of other information is degraded
Solution Approach 1:
The patent combines multiple code-containing documents into a single output document with merged code regions. This consolidation reduces the number of separate codes displayed, thereby improving the visibility and readability of the underlying document information while preserving security through the merged code structure.
Solution Approach 2:
The merged code serves multiple functions simultaneously: it maintains security information from multiple source documents, enables decoding verification, and occupies minimal space. This multi-functional code design allows the system to preserve security requirements while enhancing the overall readability and visibility of the document content.

AI summary
An apparatus for reducing a first document image and a second document image in a size and producing output images on a single sheet, the apparatus including: a creating unit configured to create a code containing information with a higher security level selected from first information contained in a code of the first document image and second information contained in a code of the second document image; and a unit configured to add the code created by the creating unit to the output image.
