How to print and apply flag labels? The solution – an industrial label printer from Etisoft
Printing and applying flag labels is a task that requires not only precision, but also the right technological tools. This becomes particularly difficult in the case of products with small diameters, where manual label application can lead to errors, crooked adhesion, or loss of legibility. In this article, you will learn how to print and apply flag labels, how to optimize this process, and how to avoid quality issues.
How to accurately print and apply flag labels – challenges of manual labeling
Manual labeling with a flag label requires exceptional accuracy on the part of the operator. The key is to keep the label’s center point glued to the product and aligned axially. Even the slightest misalignment results in a crooked flag fold, which reduces both the aesthetics and functionality of the label. The larger the label, the more visible any imperfections are – and thus the greater the risk of complaints or errors in further product identification. That’s why it’s important to know how to print and apply flag labels to avoid issues related to manual labeling and ensure maximum precision
Solution: industrial label printer from Etisoft
The answer to these challenges is a dedicated industrial label applicator – our company has developed a flag label applicator that works with the TSC Printronix T6304e thermal transfer printer. It is a compact and precise labeling station that automates the flag forming process and ensures consistent adhesion for an entire product series.
RFID tagging of hydraulic hoses and cable harnesess
Key features of the solution:
- High-resolution printing: 200, 300, or 600 dpi – ideal for barcodes, serial numbers, and small fonts.
- RFID compatibility: the printer can be used with an RFID module, which allows not only printing but also encoding UHF tags in the label.
- Dedicated adapters: Quick-change adapters are available for every product diameter or shape, ensuring stable product positioning and application accuracy.
- Range of supported products:
- Label width: 75 to 108 mm
- Label length: 15 to 50 mm
- Product diameter: 3 to 20 mm
- Maximum length of glued flag: 47 mm
- Required power supply: 230V, compressed air 5–6 bar.

Operating mode and automation capabilities
At this stage, the device operates in semi-automatic mode – the operator places the product manually in a special trolley and holds it during the label application process. Nevertheless, the system has been designed with future expansion in mind – it can be easily integrated with an industrial robot, manipulator, or automated feeder.
Thanks to Profinet-based communication, the applicator can be seamlessly integrated into existing production lines or new workstations as part of Industry 4.0 projects.

Benefits for the end user
- Elimination of errors resulting from manual labeling
- Increased repeatability and quality of markings
- Ability to handle products of different sizes thanks to adapters
- Preparation for full automation
- RFID encoding capability – one process, multiple functions.

Summary
Automatic flag labelling is the answer to manufacturers’ growing needs for product traceability, quality and aesthetics. Etisoft’s solution, based on the TSC Printronix T6304e printer and a dedicated flag applicator, is a tool that significantly simplifies the process, eliminates errors and prepares the plant for full automation.
If your products require precise labelling and manual label application is no longer sufficient, this solution may be exactly what you need.
