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: What is a stacked flexo printing machine?
A: A stacked flexo printing machine is a type of flexographic press where each color printing unit is arranged vertically in a stacked structure. It is widely used for printing plastic films, paper, and packaging materials.
Q: What materials can it print?
A: Common materials include:
Plastic films (PE, PP, BOPP, PET)
Paper and kraft paper
Laminated packaging films
Non-woven fabric
Aluminum foil (some configurations)
Q: What industries use stacked flexo printing machines?
A: Flexible packaging industry
Food packaging
Shopping bags production
Label and sticker printing
Industrial packaging materials
Q: What is the printing speed?
A: Depending on model:
Standard: 50–150 m/min
High-speed models: up to 200–250 m/min
Q: What is the number of color units available?
A: Common configurations:
2 colors
4 colors
6 colors
8 colors or more (custom machines)
Q: What is the printing accuracy?
A: Typical registration accuracy: ±0.1–0.2 mm
Depends on servo system and tension control stability
Q: What is the difference between stacked type and CI flexo machine?
A: Stacked flexo: Each color unit is independent and vertically arranged
CI flexo: All colors print on a single large central impression cylinder
CI is better for high-quality film printing; stacked is more flexible and cost-effective
Q: What is the main advantage of stacked flexo machine?
A: Flexible configuration (easy color unit adjustment)
Suitable for different materials
Lower cost compared to CI flexo
Easy maintenance and operation
Q: What is the control system used?
A: PLC control system
Servo motor drive system (for high-end models)
Touch screen HMI interface
Automatic register control system
Q: What is the drying system?
A: Depending on material:
Electric heating system
Hot air drying
Infrared (IR) drying system
UV curing system (optional)
Q: What causes poor printing registration?
A: Common reasons:
Tension instability
Material stretching or shrinkage
Servo misalignment
Improper setup of printing units
Ink viscosity issues
Q: What inks are used in flexo printing?
A: Water-based ink (most common for eco-friendly printing)
Solvent-based ink
UV ink (for special applications)
Q: Can it print shrink sleeve film?
A: Yes, stacked flexo machines can print:
PETG shrink film
PVC shrink film
OPS shrink film
But requires precise tension and drying control.
Q: What is the role of tension control system?
A: It ensures:
Stable material feeding
Accurate color registration
Reduced material stretching or wrinkling
Q: What is an anilox roller?
A: An anilox roller is a key component that transfers a controlled amount of ink to the printing plate for consistent print quality.
Q: What are common printing defects?
A: Color misalignment
Ink smearing
Uneven ink density
Wrinkles in material
Ghosting or banding
Q: Why does ink drying affect print quality?
A: If drying is insufficient:
Ink smudging occurs
Poor stacking or rewinding
If over-dried:
Material deformation
Brittleness in film
Q: Can it be integrated with slitting or die cutting?
A: Yes, it can be part of a production line:
Printing → Lamination → Slitting → Die cutting → Rewinding
Q: What is the typical setup time for a new job?
A: Simple job: 30–60 minutes
Complex multi-color job: 1–2 hours
Q: What is the lifespan of a stacked flexo machine?
A: Typically 10–15 years or more
Depends on maintenance and usage intensity
Q: What maintenance is required?
A: Cleaning anilox rollers
Checking bearings and gears
Servo system calibration
Ink system cleaning
Tension system inspection
Q: What is the biggest advantage compared to gravure printing?
A: Lower plate cost
Faster job changeover
More flexible for small and medium orders
Easier operation
Q: What is the biggest challenge in operation?
A: Color registration control
Operator skill level
Ink consistency management
Tension stability
Q: What is the difference between inline and stacked flexo machines?
A: Stacked type: Independent vertical units
Inline type: Horizontal sequence layout
Stacked is more compact and flexible.
Q: What is the most common production issue?
A: Registration drift during long runs
Ink viscosity changes
Material tension fluctuation
