Specification

4 Color Shaftless Unwinding Paper Flexo Printing Machine

The Changhong paper flexographic printing machine is a four color stack flexo press, which is designed for roll to roll printing on paper from 30 to 350 gsm, including paper cup stock.

The machine prints using water-based or solvent-based inks at a speed of 60–100 m/min depending on the substrate, artwork, ink and drying conditions.

Four-Color Stack Printing: Four print stations support multicolor graphics, logos and text for paper packaging applications.

Automatic Tension Control: Steady paper feeding as the roll diameter changes with closed loop tension control with automatic compensation.

Ultrasound Web Guidance: The ultrasonic edge control system detects lateral movement of the web and corrects it to keep the paper in position during printing.

Ceramic Anilox Rollers: Four laser-engraved ceramic anilox rollers deliver consistent ink transfer for controlled coverage. Line counts are specified to match the printing job.

Color Registration Adjustment: The machine allows the operator to manually adjust lateral and longitudinal registration to fine-tune the color registration during the operation of the machine.

Intercolor Drying: Electric drying modules between print stations dry the ink before the next color is applied for clean multi-colour results.

Stable Drive & Frame: The timing belt drive and rigid cast iron frame reduce vibration and ensure steady operation at the printing stations.

Surface rewinder for large diameters (independent drive, tension controlled) for further converting processes.

FAQ

Q1: What's the maximum production speed?
Up to 120 meters per minute — where it actually sits day-to-day depends on material thickness and how complex the design is.

Q2: How does using pneumatic roll loading make things more productive?
Roll Changes Are Faster And Less Physically Exhausting.Operators don't have to do any heavy manual lifting every time there's a swap and the downtime between rolls is kept short.

Q3. What is advantage of friction rewinder system?
Tension holds steady through the full rewind. Finished rolls come out evenly wound .

Q4: How easy is it to clean and change colors?
With the open doctor blade system, cleaning takes minutes rather than holding up the next job. 

Q5: How do you make sure the printing is right?
The synchronous belt drive and tension control system handle that between them — color registration stays on track without operators having to step in and correct it mid-run.

Q6: Can the machine be customized?
Printing width and color count — 4, 6, or 8 — can both be configured around what the production line needs. Other configurations are worth discussing during the order process.

Q7: What after-sales service do you provide?
Technical support, remote guidance, and spare parts supply are all available. It's not a hand-off once the machine ships — support stays accessible for the life of the machine.
