Common Coding and Marking Issues and Their Solutions
In modern packaging and production lines, coding and marking equipment—including batch coding machines, date coding printers, inkjet marking systems, and laser coding devices—are essential for product identification, traceability, and regulatory compliance. However, many manufacturers still face recurring operational challenges. Understanding these issues and choosing the right equipment is critical for stable production.
1. Poor Print Quality and Faded Barcodes
Common printing problems with handheld inkjet printers, continuous inkjet printers, and industrial ink coding devices include: blurry text, missing characters, or low contrast.
Solution: Use ink that matches the application, regularly clean the nozzles, and choose a reliable system. Well-known brands like Syscode and Domino provide industrial inkjet printers known for their consistent print quality.
2. Ink Stains on Plastic and Bottles
Date printers and inkjet bottle printers may struggle to print effectively on non-porous materials.
Solution: Use fast-drying ink, optimize printing distance, or adopt hot inkjet printers and thermal transfer printers (TTO printers). For long-term durability, laser coding solutions are often a better choice.
3. High Downtime and Maintenance Costs
Clogs and unplanned downtime often affect batch coders and inkjet coders.
Solution: Select mature and reliable industrial-grade continuous inkjet printers equipped with automated maintenance features. Syscode and Domino devices are widely used on high-speed production lines due to their reliability and low failure rates.
4. Inaccurate Date or Batch Coding
Manual input with handheld coding machines increases the risk of errors.
Solution: Use automatic batch coders, PLC integration, or variable data printers to ensure accurate date coding.
5. High Consumable Costs
The use of ink and ribbons increases the operational costs of ink marking systems.
Solution: Consider using fiber laser marking machines, CO2 laser marking machines, or UV laser marking machines, which require no consumables and can produce permanent codes. Desktop fiber laser marking machines and flying-spot laser marking machines are ideal for high-output production lines.
Conclusion
By choosing the appropriate marking solution—from portable inkjet printers to advanced laser marking machines—manufacturers can enhance efficiency and ensure compliance. Well-known brands like Syscode and Domino are favored for their exceptional performance, stability, and long-term value in industrial marking systems.
