You‘re running a label printing operation, and the demands keep growing—tighter tolerances, faster turnarounds, more complex jobs. The machine you choose determines whether you meet those demands or fall short.

A Flexo Printing Machine with full servo technology represents a different class of equipment: each printing unit driven independently by high-precision servo motors, delivering the registration accuracy and speed that mechanical systems can’t match. The HZ320A-8 operates at 10-150m/min with a 320mm printing width and up to 8 colors.

This guide breaks down what full servo technology actually delivers—the speed, the precision, and the operational benefits that make it a practical investment for label converters.

Independent Drive for Every Printing Unit

The defining feature of a full servo flexo press is the independent drive system. Each printing unit has its own servo motor, which fundamentally changes how the machine operates.

Why Independent Drive Matters

In a traditional flexo press, all printing units are driven by a single motor through a mechanical linkage. Registration adjustments are mechanical—you physically move gears or rollers to align colors. In a full servo press, each printing unit is driven independently. Registration adjustments are electronic, made through the control panel in seconds rather than minutes. Each unit responds independently to the control system‘s commands, eliminating the lag and drift that mechanical systems introduce.

Electronic Registration vs. Mechanical Registration

Electronic registration is faster, more precise, and repeatable. Once you dial in the registration for a job, you save the settings. The next time you run that job, the press recalls the settings and registers automatically. Mechanical registration, by contrast, relies on the operator’s skill and feel—and it has to be done from scratch every time.

Consistency Across the Run

Because each servo motor maintains its position precisely, registration stays consistent from the first meter to the last. There‘s no mechanical drift, no cumulative error. For long runs—especially on films and foils where registration tolerance is tight—this consistency is the difference between a profitable job and a costly rework.

Speed That Keeps Pace with Production

Speed is the most visible metric, but in a full servo press, speed is paired with precision.

10 to 150 Meters Per Minute

The HZ320A-8 operates at 10 to 150 meters per minute. The wide speed range means the press can handle delicate materials at slower speeds and high-volume jobs at top speed. For a label converter running diverse jobs, this flexibility is essential.

Speed Doesn‘t Compromise Quality

In a mechanical press, speed and quality are often at odds—faster speeds mean more vibration, more drift, more registration errors. In a full servo press, the servo motors maintain precision regardless of speed. You don’t have to choose between throughput and quality.

Shorter Setup Time

Setup time is a hidden speed factor. A press that takes hours to set up is slow even if it runs fast. The HZ320A-8‘s electronic registration and servo-driven adjustments reduce setup time significantly. Faster setup means more production time and shorter lead times for customers.

Precision That Reduces Waste

Precision isn‘t just about quality—it’s about cost. Every registration error creates waste.

The Cost of Registration Error

In label printing, waste is expensive. Material, ink, time—all wasted when registration drifts. A full servo press maintains registration within tight tolerances, reducing waste at every stage of the run.

Consistency Across Materials

Different materials behave differently under tension. Films stretch; papers relax. A mechanical press struggles to maintain registration across material changes. A full servo press with independent drive and tension control adapts to each material, maintaining precision regardless of the substrate.

Repeatable Setup

Once you‘ve set up a job on a full servo press, you save the settings. The next time you run that job, the press recalls the settings and registers automatically. This repeatability reduces setup waste and ensures consistent quality across repeat orders.

Applications Across Label and Packaging

The HZ320A-8 is designed for the label and flexible packaging markets, where precision and speed are non-negotiable.

Self-Adhesive Labels

The core application is self-adhesive labels for consumer goods, food packaging, and industrial products. The 320mm printing width covers the most common label sizes.

Films and Foils

Beyond paper labels, the press prints on plastic films (BOPP, PET, PVC) and foils. The independent tension control and servo-driven registration ensure consistent quality on materials that mechanical presses struggle with.

Flexible Packaging

For converters producing flexible packaging—pouches, sachets, and wrappers—the HZ320A-8 provides the precision and speed needed for high-volume production. The 8-color configuration handles complex designs with process colors and spot colors.

Questions Label Converters Ask

What’s the difference between a full servo flexo press and a mechanical flexo press?

In a mechanical press, all printing units are driven by a single motor through gears and linkages. Registration adjustments are mechanical and time-consuming. In a full servo press, each printing unit has its own servo motor. Registration adjustments are electronic, made through the control panel in seconds. The result is faster setup, more consistent registration, and less waste.

What materials can the HZ320A-8 handle?

The press handles self-adhesive labels, paper, plastic films (BOPP, PET, PVC), and foils. The independent tension control and servo-driven registration ensure consistent quality across different substrates.

How many colors can the machine print?

Up to 8 colors in a single pass. This covers process colors (CMYK) plus spot colors, which is sufficient for most label and packaging applications. For converters with complex brand work, the 8-color configuration provides the flexibility needed.
