What is a Stack Flexo Printing Machine?
Stack Flexo Printing Machine adopts a vertical stacked color group layout, which supports double-sided printing and free switching of color groups, and is especially suitable for small and medium batch, multi-variety printing scenarios. It integrates flexibility and economy, and can quickly respond to personalized order needs while ensuring printing quality, bringing cost-effective production solutions to small and medium-sized enterprises.
Printing Applications
How Does a Stack Flexo Printing Machine Work?
A stack flexo printing machine lines its printing units up vertically, and each one lays a single color onto a moving web. Tension control keeps the material running evenly through the whole job.
Step 1
Unwinding and Tension Control
The substrate comes off the unwind stand into the press. If the tension wavers, so does the print — steady tension is what keeps the web running true.
Step 2
Ink Transfer
Ink is fed to the anilox roller, which meters a set amount onto the plate. The plate then puts the image down on the substrate.
Step 3
Multi-Color Printing
The web moves through each unit one after another, and every unit adds its own color. By the time it comes out the far end, the full image is built up.
Step 4
Drying
Ink is dried between printing stages, or after them. Which one applies depends on the machine layout and the run itself.
Step 5
Rewinding and Inspection
With the last color down, the material gets checked where needed and rewound into rolls, ready for packaging or converting.

Core Advantages of Stack Type Flexo Printing Machine
01
Excellent Registration Accuracy
The registration accuracy reaches ±0.15mm, which effectively eliminates ghosting and misalignment, and ensures clear and accurate printing patterns.
02
Efficient Double-sided Printing
It can complete double-sided printing at one time, with flexible switching, which greatly improves production efficiency and saves production time.
03
Stable and Reliable
Rigid mechanical structure and precise tension control ensure long-term stable operation, reduce equipment failure rate, and ensure continuous production.
04
Flexible Configuration
The color group can be flexibly configured according to order needs, and it is easy to adjust, which can quickly adapt to the production of multi-variety and small-batch orders.
05
Space-saving Design
Vertical stacked layout, small floor area, suitable for enterprises with limited workshop space, saving workshop use cost.
06
Cost-effective
High performance and reasonable price, no need for large investment, which is an ideal choice for small and medium-sized enterprises to pursue high cost performance.
