A CI flexo printing machine, or Central Drum (CI) Type Flexographic Printing Machine, is a specialized printing device that utilizes flexographic printing technology. Here are some key points about CI flexo printing machines:
Definition and Overview
Flexographic Printing: Flexographic printing is a process that uses flexible printing plates (usually made of rubber or plastic) and fast-drying inks to transfer images onto various materials.
Central Drum (CI) Type: The "CI" in CI flexo printing machines stands for "Central Impression," referring to the central drum that serves as the impression cylinder. This design allows for efficient and precise printing.
Characteristics and Advantages
High Precision: CI flexo printing machines are known for their high precision and repeatability, making them ideal for printing on stretchable materials such as plastic film and non-woven fabrics.
Environmentally Friendly: These machines often use water-based inks, which are more environmentally friendly compared to traditional solvent-based inks.
Efficiency and Cost Savings: With advanced features like Servo control, CI flexo printing machines can achieve high efficiency in operation and production cost savings.
Customization: The machines are flexible in terms of customerized printing after-line function extensions, meeting diverse customer demands in production.
Technical Specifications
Printing Width: Typically ranges from 850 to 1800mm, depending on the model and configuration.
Maximum Machine Speed: Can reach speeds of up to 300m/min, allowing for high-volume production.
Printing Colors: Machines can be configured to print in multiple colors, commonly 4, 6, or 8 colors.
Printing Repeat: Refers to the distance between repeated images on the printed material, typically ranging from 400 to 850mm.
Additional Features
Independent Dryer: Between printing units for high drying efficiency.
Sleeve Design Printing Cylinder and Anilox Roll: For fast changeover and easy maintenance.
Servo Motor Control: In printing pressures for precise control during the printing process.
Pre-Printing and Automatic Registration System: Ensures accurate alignment of printed images.
Long-Distance Fault Diagnosis Function: Allows for remote troubleshooting and maintenance.
Automatic Unwind and Rewind Function: Enhances production efficiency and reduces waste.
