In the packaging printing industry, accurate color reproduction and optimal material handling directly determine the visual appeal and market value of products. Traditional flexo printing equipment often falls short in high-demand orders due to limitations in registration accuracy, material waste, and production efficiency, making it difficult to meet the current market needs for high-end and diversified products. Changhong launches its new 8-Color CI (Central Impression) flexo printing machine-empowered by a servo central unwinding and rewinding system, it achieves an all-round upgrade in equipment performance and production value, redefining the industry benchmarks for printing quality, efficiency, and flexibility.

ore Breakthrough: Servo Central Unwinding & Rewinding System, Redefining "Precise Control"
For tension control, traditional mechanical shaft unwinding and rewinding depend on mechanical friction or indirect transmission. This usually results in delayed responses and hard-to-avoid fluctuations, which end up directly undermining the stability of the printing process.
On the other hand, the new CI flexo press comes fitted with a servo central unwinding and rewinding system. This system enables closed-loop tension feedback and dynamic adjustments in milliseconds, fundamentally addressing the tension instability issues of traditional models. It completely eliminates hidden risks like registration deviation, pattern stretching, or compression, ensuring that every step of the printing process is under precise control.
- It delivers transformative improvements that stand out clearly: From firing up the machine and running at high speeds to unexpected emergency shutdowns, the tension curve holds steady. That wipes out the registration deviation and pattern stretching or compression problems that have always hounded traditional models-all thanks to their shaky tension control.
- Strong adaptability to ultra-flexible materials: It significantly enhances the ability to handle ultra-thin films, stretchable elastic materials, and sensitive metal foils. This reduces wrinkles, deformation, and material waste in the production process.
- Pre-registration & quick job changeover: When paired with the automatic registration system, the servo unwinding and rewinding system allows for accurate pre-registration. This drastically cuts down setup time, making it more efficient to handle small-batch and multi-order production tasks.
- Reduced material waste: Precise tension control cuts down startup waste and running rejects, directly improving your profit margin.
Performance Leap: 8-Color CI Flexo Printing Machine Design Paired with Servo Unwinding & Rewinding System
- Top-tier registration accuracy: The CI Flexo Machine already delivers great registration stability on its own. When combined with the servo unwinding and rewinding system's precise feeding, it meets the strict demands of label and packaging printing.
- Better production speed & stability: It gets rid of speed limits and mechanical transmission interference, letting the machine run steadily at its higher designed speeds and boosting overall output.
- Intuitive, user-friendly operation: The central console's built-in touchscreen lets you monitor in real time, set tension parameters for each unit precisely, and save those settings easily.With digitized processes, operation is simpler and repeatability is excellent.
Wide material compatibility:
Films: PE, PP, PET, BOPP, Nylon, etc.
Papers: Coated paper, label paper, cardboard, thin specialty paper.
Composite materials: Aluminum foil, aluminized film, non-woven fabric, lightweight textiles.
Specialty materials: Stretchable PE cling film, sensitive thermal materials, etc.

FAQ
Q1: Is the servo unwinding and rewinding system energy-intensive?
A1: On the contrary. Servo motors supply energy on demand, consuming minimal power at low speeds and standby. The material savings and production efficiency gains brought by its high performance result in far higher overall energy efficiency than traditional models.
Q2: What products is this 8 color flexographic printing machine suitable for?
A2: It is ideal for high-end labels (e.g., pharmaceutical and daily chemical products), flexible packaging (e.g., food and beverage bags, plastic bags), film & plastic packaging, and any printed products with strict requirements for color consistency and registration accuracy.
Q3: Will operation and maintenance be more complex?
A3: Operation is more intelligent, with most parameters set with one click. For maintenance, the servo system features a relatively simple structure, eliminating vulnerable parts like traditional mechanical clutches. It boasts higher reliability and more planned maintenance.
Q4: Is investing in this flexo machine worthwhile?
A4: If you are facing diversified orders, increasingly complex materials, and rising demands for quality and delivery time, this equipment will quickly deliver returns through improved quality, reduced waste and enhanced flexibility, while helping you explore higher-margin markets.
