All the rollers are deal with high temperature.
Characteristics:
1) The main motor adopts imported inverter to govern a stepples speed adjustment.
2) The printing units are all equipped with a group of infrared dryers respectively.
3) Each IR dryer device of printing unit
4) Feeding and rewinding are controlled through magnetic particle brake and clutch (Japanese Mitsubishi auto tension controller).
5) Un winder and re winder adopt air core holder.
6)one unit rotary station
7) Adopt ceramic anliox roller which offers durability, wear resistance and corrosion resistance, also is more efficient on production by reducing the times of changing rollers.
8) The printing unit can register in 360 degrees. Each printing unit can be independently geared and loosen to have rest of units continue to printing.
9) The inking roller will be automatically off impression when press stop and rotate at lower speed in order to keep the ink from being drying.
10) Paper unwind, printing, laminating, rotary diecutting, waste removal and rewinding can be processed in one pass. It has characterized by wide application, fast printing speed and high economic efficiency ink will not contaminate environment. So it is an idea printing machine for the business form, Tag and high end pressure sensitive label.

FAQ
Q: 1What is the minimum repeat length of stacked flexo machine?
A: Typical range: 250 mm – 600 mm
Depends on gear system or servo control configuration
Q: Can the machine handle very thin films?
A: Yes, but requires:
Stable tension control system
Anti-static device
Proper drying temperature control
Thin films like 20–30 micron PE/PP need careful setup.
Q: What causes material stretching during printing?
A: Common reasons:
Excessive web tension
High drying temperature
Poor material quality
Improper unwind brake control
Q: Why do colors look inconsistent during long runs?
A: Possible causes:
Ink viscosity change (solvent evaporation)
Anilox roller clogging
Ink temperature variation
Speed fluctuation
Q: What is the role of servo control in flexo machines?
A: Servo system controls:
Print registration accuracy
Web feeding stability
Color-to-color alignment
Speed synchronization between units
Q: What is doctor blade function?
A: Doctor blade is used to:
Scrape excess ink from the anilox roller
Ensure consistent ink transfer
Improve print sharpness and clarity
Q: What causes ghosting in flexo printing?
A: Incorrect impression pressure
Uneven anilox ink distribution
Vibration in printing unit
Poor ink formulation
Q: Can the machine print reverse (inside printing)?
A: Yes, stacked flexo machines can be configured for:
Surface printing
Reverse printing (inside film printing for packaging)
Q: What is the difference between open gear and gearless (servo) system?
A: Open gear system: Traditional, lower cost, more mechanical adjustment
Gearless servo system: High precision, faster setup, better registration stability
Q: What is the main cause of color misalignment?
A: Tension instability
Servo encoder error
Material expansion/shrinkage
Incorrect pre-registration setup
Q: Can stacked flexo print multi-layer laminates?
A: Yes, but requires:
Strong drying system
High ink adhesion
Stable tension control to avoid delamination
Q: What is the role of corona treatment unit?
A: Corona treatment improves:
Ink adhesion on plastic films
Surface energy of materials like PP/PE
Without it, ink may peel off or print poorly.
Q: Why does ink not dry properly?
A: Low drying temperature
High machine speed
Poor ventilation in drying tunnel
Excess ink thickness
Q: What is the maximum printing width?
A: Common configurations:
600 mm / 800 mm / 1000 mm / 1200 mm
Q: Can stacked flexo machine do lamination inline?
A: Yes, optional inline lamination unit can:
Combine printed film with barrier film
Improve packaging strength and barrier properties
Q: What is the most common setup mistake for operators?
A: Incorrect tension setting at unwind/rewind
Wrong impression pressure adjustment
Poor ink viscosity control
Q: Why do edges wrinkle during printing?
A: Uneven tension distribution
Misaligned rollers
Substrate thickness variation
Excessive drying heat
Q: What is the ink viscosity range for flexo printing?
A: Water-based ink: 20–40 seconds (Zahn cup #3)
Solvent ink: varies depending on formulation
Q: Can the machine run at low speed for testing?
A: Yes, usually:
Setup mode: 5–30 m/min
Production mode: full speed 50–250 m/min
Q: What is the biggest advantage of stacked flexo in small orders?
A: Fast job changeover
Lower plate cost
Flexible configuration
Easy adjustment for different designs
Q: What causes printing banding or stripes?
A: Worn anilox roller
Vibration in printing unit
Ink starvation
Inconsistent pressure
Q: How often should anilox rollers be cleaned?
A: Light cleaning: daily or per shift
Deep cleaning: weekly or depending on ink type
Q: What is the lifespan of printing plates?
A: Typically 1–3 million impressions depending on care and material
Q: What is the key factor affecting print quality?
A: Registration stability
Ink consistency
Tension control
Operator setup accuracy
Q: What is the biggest limitation of stacked flexo machines?
A: Slightly lower print quality compared to CI flexo for ultra-high-end packaging
Requires skilled operators for stable long-run production
