3. Inline Printing Process: The flexographic printing process used in CI Flexo Presses involves the transfer of ink from the anilox roller to the printing plate, which then transfers the ink onto the substrate. The substrate is guided through the press, passing through each color station to receive successive layers of ink.
4. Precise Registration Control: CI Flexo Presses are equipped with advanced registration control systems to ensure accurate alignment of multiple colors. This helps in achieving sharp and vibrant prints with minimal color overlap or misalignment.
5. Drying Systems: To facilitate the fast drying of inks and coatings, CI Flexo Presses often incorporate drying systems, such as hot air dryers or UV curing units. These systems help to speed up the printing process and ensure the printed materials are ready for further processing or immediate use.
6. Flexibility and Versatility: CI Flexo Presses are known for their flexibility, allowing for printing on a wide range of substrates and accommodating various ink types. They can handle different web widths and support various printing applications, including labels, flexible packaging, folding cartons, and more.
7. Automation and Control: Modern CI Flexo Presses often feature advanced automation and control systems. These systems may include computerized job setup, electronic registration control, touchscreen interfaces, and other features that enhance productivity, ease of use, and overall printing quality.

6. Specialty Printing: CI Flexo Presses are utilized for specialty printing applications, such as printing on metallic substrates, holographic materials, or textured surfaces. These presses can create unique visual effects and add value to packaging or labeling by incorporating special coatings, spot varnishes, or foiling.

It’s important to note that CI Flexo Presses are highly adaptable and can be customized to meet specific printing requirements. The applications mentioned above represent some of the common uses, but the versatility of CI Flexo Presses allows them to be employed in various other industries and printing applications where high-quality, multi-color printing is required.

The relationship between CI Flexo Press and Film Coating Machine is that they are two different types of equipment used in the printing and coating processes.

CI Flexo Press, or Central Impression Flexographic Press, is a printing machine used in the packaging and labeling industry. It utilizes a central impression design to transfer ink from multiple color stations onto the printing plate and then onto the substrate. CI Flexo Press enables multi-color printing with precise registration control and is used for printing labels, flexible packaging materials, folding cartons, and more.

Film Coating Machine is a coating equipment used to apply films, coatings, or coatings to substrates. It typically includes a feeding system, coating head, drying system, and winding system. Film Coating Machines are used to apply protective films, glossy films, adhesives, coatings, etc., onto substrates for protection, decoration, or functionality.

While both CI Flexo Press and Film Coating Machine are used in the printing and coating processes, they serve different purposes. CI Flexo Press is primarily used for printing multi-color patterns and text, while Film Coating Machine is mainly used for applying films, coatings, or coatings. In certain applications, these two machines may be used sequentially, such as using Film Coating Machine to apply a protective film after printing is completed.

The simultaneous use of CI Flexo Press and Film Coating Machine, as well as their sequence in the process, would depend on the specific application requirements and the desired outcome.

Technical advantages

Using the internet and Al technology, EVER-POWER always strives for intelligent production. CINOVA adopts multiple intelligent devices with a smart system, which helps factories improve production efficiency and reduce labor and running costs.

Intelligent printing control

• Intelligence system for error proofing and error correction

The function is intended to prevent the machine from damage caused by human errors. The Drive Motor Torque Protection function enables the machine to stop if the torque increases abnormally, thus avoiding damage to the plate. The Tolerance Protection function allows the device to control if position tolerance exceeds 3mm at both ends of the roller, thus preventing damage to the sleeve and mandrel.

• Automatic pressure compensation

The function adjusts the print pressure automatically when machine speed changes, thus avoiding the register tolerance and color difference caused by pressure changes.The function helps the machine stable print when the machine speed changes.

• Printing length measuring

The system will measure the print length in real time and send the feedback tension system. The system will automatically adjust to ensure variable print length, thus reducing the defect rate.

• Solvent concentration real time monitoring

The function monitors solvent concentration at the print unit and main heating oven. When solvent concentration increases to a certain limit, the system will trigger an alarm and adjust the air speed discharged to the exhaust pipe.

• Drive motor torque self-adaption

The function is intended to optimize unstable register precision caused by changing to a bigger printing plate or long-running machine. Using one-key motor optimization, the system automatically identifies the control parameters and enables the print roller motor to run stably.

• Speed self-adaption control system

By comparing the torque value and adjusting the anilox motor speed, the system will reduce the torque difference and eliminate the ink bar caused by a bit of heavy pressure printing.

• Print unit constant temperature Control system

With a unique structure and circulating cooling system, the print mandrel is protected from heat, which may cause the print dot to expand and the plate to dry. This enables the print mandrel to vary in temperature and enhances the plate service life, thus improving the printing quality and the rate of finished products.
