What is CI Flexo Press?

CI Flexo Press, also known as Central Impression Flexographic Press, is a type of printing machine used for flexographic printing in the packaging industry. It is a high-speed and efficient press designed for printing on flexible materials such as films, papers, and labels.

CI Flexo Press operates on the principle of central impression, where the printing material is guided around a central drum while the printing plates are mounted on the outer surface of the drum. This configuration ensures consistent and uniform pressure on the printing material, resulting in high-quality prints.

How does the printing process work on a CI flexo press?

1. Anilox Roller:

   • The ink is first transferred to an anilox roller, which is a precisely engraved cylinder with tiny cells.   
      
   • The depth and volume of these cells determine the amount of ink transferred to the printing plate.   
      

2. Printing Plate:

   • The inked anilox roller transfers ink to the raised areas of the flexible photopolymer printing plate.   
      
   • The plate contains a mirror image of the desired design.   
      

3. Impression Cylinder:

   • The substrate (e.g., paper, film, foil) is fed into the press and wrapped around the large impression cylinder.   
      
   • As the cylinder rotates, the substrate comes into contact with the inked printing plate.   
      

4. Ink Transfer:

   • The ink is transferred from the printing plate to the substrate under pressure.
   • The amount of pressure and the dwell time between the plate and the substrate influence the final print quality.

5. Drying:

   • After each color station, the printed substrate may pass through a drying unit to dry the ink before the next color is applied.   
      
   • Drying methods can include air drying, infrared drying, or UV curing.

6. Finishing:

   • Once all colors have been printed, the substrate may undergo additional finishing processes, such as lamination, coating, or slitting.   
      

What are the advantages of CI flexo printing compared to other printing methods?

Versatility in Substrates

• Wide Range of Materials: CI flexo can print on a vast array of substrates, including paper, plastic films, foils, and non-woven materials.   
   
• Adaptability: It can handle various thicknesses and surface textures, making it suitable for diverse packaging needs.   
   

High-Quality Printing

• Sharp Image Resolution: CI flexo delivers high-quality prints with sharp details and vibrant colors.   
   
• Consistent Color Reproduction: Precise color control ensures consistent print quality across large runs.   
   

High-Speed Production

• Efficient Production: CI flexo presses are designed for high-speed production, reducing turnaround time and increasing output.   
   
• Cost-Effective: High-speed production lowers the cost per unit, making it a cost-effective solution for large-volume printing.

Low Waste and Environmental Friendliness

• Minimal Waste: Precise registration and efficient material handling minimize waste, reducing environmental impact.   
   
• Eco-Friendly Inks: CI flexo often utilizes water-based or UV-curable inks, which are more environmentally friendly than solvent-based inks.   
   

Cost-Effective

• Lower Plate Costs: Flexographic plates are relatively inexpensive compared to other printing methods.   
   
• Reduced Setup Time: Quick plate changes and setup times contribute to lower production costs.  
   

Short Lead Times

• Faster Turnaround: The high-speed production capabilities of CI flexo presses allow for shorter lead times, especially for urgent orders.   
   

CI Flexo Press Applications

• Flexible Packaging: This is the most common application. CI flexo presses are ideal for printing on materials like:
  • BOPP (Biaxially Oriented Polypropylene): Used for food packaging, labels, and more.
  • PET (Polyethylene Terephthalate): Used for bottles, trays, and other rigid packaging.
  • PE (Polyethylene): Used for bags, liners, and other flexible packaging.
  • CPP (Cast Polypropylene): Used for food packaging and lamination.
• Labels: CI flexo presses can print high-quality labels for various products, including food, beverages, pharmaceuticals, and consumer goods.
• Paper Products: They can be used for printing on paper-based materials like cartons, boxes, and envelopes.
• Non-Woven Fabrics: CI flexo presses are capable of printing on non-woven fabrics used in hygiene products, medical applications, and geotextiles.
• Specialty Applications: Other applications include printing on foils, films, and heat-shrinkable materials.

About EVER-POWER

EVER-POWER is a leading provider of cutting-edge printing equipment, and their flagship product, CINOVA, represents the new generation of Cl Flexo Press. CINOVA is engineered with aerospace precision manufacturing technology, meeting market demands for intelligence, high-speed, stability, and convenience while aligning with the emerging environmental trends.

To meet unique client requirements, EVER-POWER has developed an innovative LED-UV drying system. This system utilizes a two-stage UV drying process. In the first stage, ultraviolet light and ink react, initiating surface drying. In the subsequent re-dying stage, any acidic substances produced during the first stage react with the remaining ink, ensuring complete and thorough drying. Notably, the LED-UV drying system outperforms traditional heating methods in energy consumption, pollution control, and heating safety. Its ability to solidify at low temperatures makes it particularly suitable for heat-sensitive materials, plastic films, and bills.

At EVER-POWER, the mission is to revolutionize the printing industry by delivering state-of-the-art solutions that combine precision manufacturing, efficiency, and environmental consciousness. With CINOVA and the innovative LED-UV drying system, EVER-POWER empowers businesses to achieve exceptional print quality, increased productivity, and sustainable printing practices. Join the revolution and experience the future of printing with EVER-POWER.

In addition, EVER-POWER also supplies the following products: film coating machines, various gearboxes, chains, sprockets, gears, pulleys, etc. All transmission related accessories can be found in our company.
