One of the most common points of time loss on production lines is the date coding process. A nozzle blockage, incorrect date information, or a slow drying rate—each error measured in minutes but which can collectively lead to the loss of thousands of products.
Therefore, an efficient inkjet date coding system not only "writes" but also codes accurately and consistently without interrupting production.
This guide, based on the field experience of Electrojet engineers, 7 effective ways to increase coding efficiency .
1- Automatic Date and Lot Update
Manual date changes are one of the most common sources of human error. If the date isn't updated during a shift change, thousands of products will ship with incorrect information.
Solution:
In Electrojet inkjet systems, production dates and lot numbers are integrated into the ERP system or the internal clock module. This ensures that date information is automatically updated daily, eliminating the need for user intervention.
Extra tip: On the software side, fix the date formats (DD.MM.YYYY or YYYY-MM-DD). This reduces errors in the reporting process.
2- Automatic Cleaning Cycle to Reduce Downtime
One of the biggest factors that reduces coding efficiency is nozzle clogging. Manual cleaning is both time-consuming and increases solvent consumption.
Electrojet JetPro seriesprintheads feature an automatic "self-clean" function. This system cleans the nozzle between production runs, eliminating downtime.
Conclusion:
- No need for extra cleaning at the beginning of each shift
- Less ink waste
- Consistent print quality
3- Speed Synchronization: Automate Encoding and Band Matching
When production line speed changes, coding density also changes. This can create unreadable codes or overlapping print on some products.
Solution:
Electrojet control software analyzes data from the belt speed sensors in real-time and automatically adjusts the printing frequency.
Thanks to this synchronization:
- Each product is coded at the same distance
- Font height and readability remain constant
- Print clarity remains intact even with increased speed.
Pro tip: Be sure to activate the machine's "Encoder" connection; this will increase speed efficiency by 100%.
4- Smart Ink Management
One of the hidden factors affecting production efficiency is ink and solvent optimization. As ink density changes, so do print color, drying time, and readability.
Electrojet's InkFlow Management system;
- Automatically measures ink viscosity,
- Adds solvent if necessary,
- Maintains optimum density with every print.
This system reduces ink consumption and minimizes environmental impact
5- Correct Printing Position and Automatic Distance Calibration
Product sizes and packaging types can vary across production lines. Even a 1–2 mm change in the printhead distance during manual adjustments will reduce print quality.
The automatic Z-axis calibration system found in Electrojet inkjet printers detects product height and adjusts the print head position with millimeter precision.
Benefits:
- No calibration required for product changes
- Constant print density
- Minimum errors in fast format transitions
6- Digital Tracking of Production Data
Efficiency starts not only on the production line but in data management . Electrojet systems automatically record every code printed during the production process. These records include date, time, batch number, and operator information.
This data traceability and plays a crucial role in error analysis processes.
Additional tip: Review the reporting module weekly. Identifying which shifts have more errors will help optimize processes.
7- Regular Maintenance and Operator Training
The human factor is as important as the technology. Devices without regular maintenance shorten nozzle life, contaminate sensors, and reduce print performance.
The Electrojet maintenance plan includes the following routines:
- Weekly filter check
- Monthly print head cleaning
- Full system calibration every 6 months
Additionally, short-term training for operators:
- Ink change,
- Software settings,
- Troubleshooting steps
should be taught.
Electrojet technical team provides these trainings free of charge, on-site or online.
Every Second is Valuable, Every Code Must Be Perfect
Production line downtime costs lost production capacity, and poor print quality costs customer confidence.
Increasing productivity relies on the right combination of technology, automation, and training . Electrojet inkjet systems combine these three areas in a single platform, making your production lines seamless, reliable, and efficient
