Compact Binary Monitoring Codes for Print Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems face challenges in synchronizing large print jobs without using conventional barcodes, which are large and interfere with the print image, especially when dealing with multiple shorter documents without page numbers, and automatic scanning of page numbers is complex.
Innovation Solution
A method that generates and uses smaller monitoring codes, such as one-, two-, or three-digit binary numbers, which are printed on each page and automatically read to ensure synchronization, allowing for the use of pseudo-random number generators to create sequences that can monitor a large number of pages with minimal redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional barcodes are used for monitoring, then data integrity can be verified, but the barcodes are large and significantly affect the print image
Solution Approach 1:
The patent changes the parameter of the monitoring code from conventional large barcodes to compact binary codes consisting of only one to three digits. This parameter change reduces the area occupied by the monitoring code from significant portions of the page to minimal space, while maintaining the ability to verify data integrity through the binary sequence
Solution Approach 2:
The patent uses simple binary digits (0 and 1) as the monitoring code instead of complex barcode structures. These minimal binary codes are disposed of in the print image without requiring space for large graphical representations, achieving verification functionality with the simplest possible code structure
2Area of moving object
If page numbers are used instead of barcodes, then the monitoring mark area is reduced, but automatic scanning of page numbers is significantly more complicated
Solution Approach 1:
The patent applies local quality by placing specific binary monitoring codes at defined positions in the print image. Rather than using full page numbers that require complex recognition, simple binary digits (0 or 1) are positioned in specific locations, making them easy to scan automatically while occupying minimal space
Solution Approach 2:
The patent changes the parameter of the monitoring information from multi-digit page numbers to one-to-three-digit binary codes. This parameter reduction simplifies the scanning process significantly, as the system only needs to recognize simple binary patterns rather than parse complex page number formats
3Reliability
If conventional barcodes are used, then monitoring can be achieved, but the codes are very large and do not allow for minimal information content
Solution Approach 1:
The patent segments the monitoring information into minimal binary units (digits 0 and 1). Instead of using large barcodes containing extensive information, the monitoring function is achieved through segmented binary sequences of one to three digits, reducing the quantity of information while maintaining monitoring reliability
Solution Approach 2:
The patent extracts only the essential monitoring information needed for verification, removing all extraneous elements. By using pure binary codes without additional graphical elements or large data structures, the system achieves monitoring with minimal information content, taking out only what is absolutely necessary for the function

AI summary
In a method or system for monitoring of printed data in a printing system, a monitoring code for a respective page to be printed of a recording medium is generated. The monitoring code is printed on the respective page. The printed monitoring code is automatically read and evaluated such that monitoring numbers that are not contained in numerical succession in a monitoring list are used as the monitoring codes.
