RFID Tag Verification for Print Job Collation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern print shops face challenges in accurately assembling and delivering print jobs due to errors in document processing and handling, such as incorrect document matching and mixing, which can result in incomplete or misaddressed print products, especially when special processing instructions are not used or when space is required for processing codes, affecting the appearance and coordination of documents.
Innovation Solution
A verification system that includes a printing device with paper sources equipped with electronic data storage devices containing identification information, a quality control reader, and a computer system to manage and verify the assembly and sorting of print jobs, ensuring correct collation and delivery by reading and comparing identification information on each page to maintain the integrity of the print job.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional printing methods are used without special marks, then document appearance is maintained and processing is simple, but document identification and verification reliability deteriorates
Solution Approach 1:
The patent extracts the identification function from the document content itself and places it in a separate electronic data storage device attached to the paper. This allows the document to maintain its original appearance while the verification system uses the electronic device to provide reliable identification through reader devices that scan the storage devices during printing and assembly processes.
2Reliability
If special marks are added to documents for processing instructions, then document processing accuracy is improved, but document appearance deteriorates and space coordination becomes complex
Solution Approach 1:
The patent removes the special marks from the document surface and replaces them with electronic data storage devices that contain identification information. The reader devices detect this information without requiring visual marks on the document, thereby maintaining document appearance while ensuring processing accuracy through electronic verification.
Solution Approach 2:
The patent substitutes the mechanical/optical system of visual marks and human reading with an electronic system where reader devices automatically scan and verify identification information from electronic data storage devices. This electronic substitution eliminates the need for special marks while maintaining processing accuracy.
3Adaptability or versatility
If multiple print runs with different specifications are processed, then printing flexibility is improved, but error rate in document matching increases
Solution Approach 1:
The patent implements feedback mechanisms where reader devices continuously verify identification information from electronic data storage devices during the printing and assembly process. The system compares the verified information against expected parameters and provides feedback to correct mismatches, thereby maintaining high document matching accuracy even across multiple print runs with different specifications.
Solution Approach 2:
The patent applies preliminary verification actions by scanning and verifying identification information from electronic data storage devices before the actual printing and assembly processes begin. This preliminary check ensures that the correct documents are selected and associated with the appropriate processing instructions, preventing matching errors before they occur.
4Reliability
If electronic data storage devices are attached to each paper, then document verification reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs inexpensive electronic data storage devices that can be easily attached to and removed from paper sheets. These disposable-like storage devices are cost-effective and simple to integrate into the printing process, offsetting the added complexity by providing reliable verification at minimal cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively ensures complete and correct assembly of print jobs by verifying identification information, reducing errors in document handling and maintaining the quality and accuracy of print products, while also improving the efficiency of the printing process and eliminating the need for additional space or special marks on documents.
Implementation Method 1
Each piece of paper has an electronic data storage device attached thereto. Each electronic data storage device has identification information stored therein.
Implementation Method 2
a quality control reader device adapted to sense the identification information stored in the electronic data storage devices
Data Source
AI summary
A verification system includes at least one printing device utilizing paper having an electronic data storage device attached thereto. Each electronic data storage device has identification information stored therein. A quality control reader device senses the identification information stored in the electronic data storage devices. The identification information of each printed page is associated with the print job. After all of the printed pages of the print job are assembled, the identification information of the assembled printed pages is read and compared to the identification information of the pages associated with the print job to determine if the print job is complete and correct.
