Preventing Duplicate Barcode Printing in Manufacturing: Effective Solutions
As manufacturing and industrial management become more sophisticated, products often receive unique barcode labels, such as serial number barcodes or sequential codes, during production. This practice is crucial for better product tracking and management, especially in industries such as food safety, medical devices, and high-precision electronics. However, preventing barcode duplicates can be challenging during bulk printing.
Common Causes of Barcode Duplication
1. Power Outages and Network Issues
Sudden power outages, USB disconnections, or network failures might result in the last print job being reprinted when everything gets back to normal, which can lead to duplicate barcode printing.
2. Cache or Memory Overflow
During bulk barcode printing, excessive content can lead to printer memory mismanagement, resulting in duplicate tasks. Similarly, computer performance issues may cause repeated print job submissions, leading to barcode duplication.
3. Paper and Ribbon Changes or Interruptions
Mid-printing replacements of label paper or ribbons might cause the printer to stop. Resuming printing post-replacement may lead to duplicate or missed barcodes.
Solutions for Preventing Barcode Duplicates
These situations can all lead to barcode duplication. To mitigate the impact of duplication and associated quality issues, comprehensive checks on printed barcodes are essential to identify and remove duplicates before they enter the production line.
Methods to Prevent Duplicate Barcode Printing
1. Manual Scanning and Inspection
Some factories, due to cost considerations or low automation levels, employ personnel to manually scan and inspect printed barcodes. While this method helps prevent barcode duplicates, it is labor-intensive and prone to human error.
2. Automated Scanning Systems
Custom automated scanning equipment can replace manual inspection, increasing efficiency and reducing labor costs when detecting barcode duplicates. These systems use high-precision scanners and advanced software to analyze and flag problematic barcodes in real-time.
3. Barcode Printers with Verifier
In fields like food safety, medical devices of UDI systems, and high-precision electronics manufacturing, the integration of barcode printing and inspection is becoming more prevalent.
HPRT's barcode printers with verifier combine high-resolution industrial barcode printers with OCR (Optical Character Recognition) modules, allowing for simultaneous barcode printing and verification.
These integrated barcode printer and verifier can continuously scan and inspect barcodes during printing, detecting duplicates, omissions, errors, and unreadable barcodes, and automatically halt production to prevent faulty barcodes from entering the production line. This ensures barcode compliance and product traceability in the supply chain.
Barcode duplication is a significant challenge in modern manufacturing. Thorough inspection and monitoring of anomalies during the printing process can effectively reduce duplication.
