Central Impression Printing Press, abbreviated as CI Printing Press, is a high-precision printing device that adopts a Central Impression (CI) design. Its core structure consists of a large central impression cylinder, around which the printing substrate (such as paper, film, etc.) is evenly wrapped. Multiple printing plate units work synchronously around the cylinder to achieve high-speed, multi-color, and high-quality printing. This type of press is widely used in flexographic and gravure printing fields, especially suitable for packaging, labels, and film printing.
Central Impression Design
The printing material wraps around the central cylinder, ensuring even distribution of material tension, improving registration accuracy and printing consistency.
Multi-Color Printing Capability
Multiple printing stations operate simultaneously to achieve high-quality multi-color printing with four, six, or more colors.
High-Speed Production
Supports high-speed continuous operation to meet large-scale production demands and improve production efficiency.
Automated Control System
Uses a digital operation interface and automatic tension and registration adjustment systems to simplify operation and ensure production stability.
Wide Range of Applicable Materials
Compatible with various printing substrates, including plastic films, paper, composite films, and other flexible materials.
Efficient Drying and Curing
Combines hot air, infrared, or UV drying equipment for rapid ink drying and curing to ensure printing quality.
Environmentally Friendly and Energy-Efficient Design
Compatible with eco-friendly water-based and UV inks, energy-efficient operation, meeting modern environmental standards.
Packaging Printing (flexible packaging films, plastic bags, cartons, etc.)
Label and Barcode Printing
Gift Packaging and Promotional Item Printing
Electronics Product Packaging Printing

● The machine introduction & absorption of European technology / process manufacturing, supporting / full functional.
● After mounting the plate and registration, no longer need registration, improve yield.
● Replacing 1 set of Plate Roller (unloaded old roller, installed six new roller after tightening), only 20 Minute registration can be done by printing.
● The machine first mount plate, pre-trapping function, to be completed in advance prepress trapping in the shortest possible time.
● Maximum production machine speed up 200m/min, registration accuracy ±0.10mm.
● The overlay accuracy does not change during lifting running speed up or down.
● When machine stop, Tension can be maintained, the substrate is not deviation shift.
● The whole production line from the reel to put the finished product to achieve non-stop continuous production, maximize product yield.
● With precision structural, easy operation, easy maintenance, high degree of automation and so on, only one person can operate.
