Servo-Driven Stack Flexographic Press
Honor Servo-Enhanced Stack-Type Flexographic Printing System for Flexible Packaging
This upgraded stack-type flexographic printing system is engineered for flexible packaging production with vertically or horizontally stacked, independent color stations. Unlike central impression (CI) systems where all colors share one impression drum, each printing unit carries its own anilox, impression cylinder, and ink system—delivering modular maintenance, economical operation, and straightforward 4- or 6-color configurations.
Machine Architecture
Servo-Enhanced Stack Architecture for Higher Throughput
Integrated servo motion, hybrid drive, and stack modularity work together to keep tension stable, color stations independent, and changeovers manageable on narrow and medium web jobs.
Servo-Enhanced Stack Structure
The machine retains the vertical or horizontal stack architecture of conventional stack flexo, but integrates servo control into key motion axes—significantly improving color registration, synchronization between units, and stability at higher production speeds.
- Anilox roller system per unit
- Impression cylinder per unit
- Modular ink supply and doctoring
- 4- and 6-color stack configurations
Hybrid Gear + Servo Drive System
Unlike purely mechanical stack machines, this platform uses a hybrid gear and servo transmission—combining the stability of industrial gearing with servo motors for precision correction, compensation, and multi-color synchronization.
- Hybrid gear + servo transmission
- Servo motors for precision correction
- Lower cost than full servo gearless CI systems
- Improved registration vs standard stack machines
Servo Registration & Color Control
Servo-assisted registration delivers automatic color correction, improved multi-color synchronization, and tighter control during acceleration and deceleration—supporting higher stable speeds on flexible film and paper stocks.
- Servo-assisted automatic registration
- Improved multi-color synchronization
- Automatic color correction during speed changes
- Ideal for 4–6 color packaging graphics
Advanced PLC Control System
PLC-based control coordinates servo motion, tension loops, and printing units—supporting automatic register control, multi-axis synchronization, and recipe-based changeovers for repeat jobs.
- PLC-based machine control
- Servo + load-cell hybrid tension system
- Stable feeding for 10–200 µm substrates
- Automatic register control (optional edge guidance)

Stack Printing
Independent color stations print sequentially in the stack with gear-driven synchronization.
Inter-station Drying
Each unit can integrate drying capacity to stabilize ink before the next color deck.
Web Transfer
Material passes through the stack to the next color or finishing module with controlled tension.
Rewind
Servo torque rewind produces finished rolls up to 800 mm diameter for downstream converting.
Optional Components

Why Converters Upgrade to Servo-Enhanced Stack Flexo
| Factor | Servo-Enhanced Stack | Standard Stack Flexo |
|---|---|---|
| Registration | Servo-assisted ±0.10 – 0.15 mm | Mechanical ±0.15 – 0.25 mm |
| Stable speed | 120–200 m/min production range | Typically up to 150 m/min |
| Multi-color jobs | 4- and 6-color stack capability | Best on simpler color counts |
| Investment | Mid-range upgrade path | Lowest entry cost |
| Best fit | Medium-to-high quality packaging | Entry-level daily packaging |
- Improved registration — servo correction significantly improves color stability over standard stack machines.
- Lower cost than CI — bridges the gap between entry stack flexo and high-end CI platforms.
- Flexible expansion — modular units can be maintained and upgraded independently.
- Multi-substrate capability — film, paper, and nonwoven within the rated thickness range.
FAQ
Common Questions About Servo-Enhanced Stack Flexo
It keeps the stack-type independent unit architecture, but adds integrated servo control for registration, synchronization, and higher stable speeds—without the capital layout of a full CI platform.
This platform supports BOPP, OCPP, pearlized film, paper, kraft paper, woven fabric, and other flexible substrates from 10 to 200 microns, subject to final process validation.
Choose servo-enhanced stack when you need better registration and 4–6 color output at mid-range investment. CI remains the choice for the highest-end graphics and sustained ultra-high-speed production.
