Equipment used in flexographic printing machines is designed to enhance print quality, optimize production speed, and ensure efficiency. Below are the main equipment used in flexographic printing machines:
- Printing Cylinder (Anilox Cylinder)
- Function: Plays a crucial role in the quality of flexographic printing. The ink is transferred smoothly to the surface by this cylinder. The anilox cylinder has microscopic cells and transfers the correct amount of ink to the printing plates.
- Features: The cell structure of the anilox cylinders affects the color density and quality of the print.
- Printing Plate
- Function: Flexographic printing uses printing plates to transfer ink to the surface. These plates are made of high-quality polymers and are placed flexibly on the printing surface.
- Features: Typically, photopolymer plates are used, which are shaped to transfer ink to the surface during the printing process.
- Ink Unit
- Function: The ink unit controls the amount and pressure of ink used during printing. The ink is transferred to the anilox cylinder through this unit.
- Features: This unit regulates the color density and ink distribution.
- Touch Control Panel (Automation System)
- Function: The digital panel used to manage and control the functions of the printing machine. The user can adjust printing parameters (printing speed, ink level, temperature, etc.).
- Features: Modern flexographic printing machines typically use touch screens, making it easy and fast for the operator to manage the machines.
- Drying Unit
- Function: Ensures the rapid drying of ink on the printed surface. The drying process may vary depending on the type of ink used (water-based, UV-based, solvent-based).
- Features:
- UV Drying Unit: Ensures quick drying of ink with UV light.
- Heat Drying System: Uses heat to dry the ink, typically used for water-based inks.
- Tension Control System
- Function: Ensures the material used during printing is fed smoothly. Tension control maintains a smooth printing surface and ensures the material progresses at the correct speed.
- Features: Prevents material breakage or wrinkling, ensuring the print quality is maintained.
- Printing Machine Team Sequence System
- Function: Organizes the sequence of printing jobs in flexographic printing machines. This system ensures the smooth transition between different printing jobs.
- Features: Allows quick color changes and ensures continuous production.
- Printing Paper or Film Feeding System
- Function: Ensures that the material to be printed (paper, plastic film, foil, etc.) is fed smoothly into the printing machine.
- Features: Equipped with adjustable tension systems to feed the material smoothly into the machine.
- Rotating Table (Roller)
- Function: Rotating tables are needed to transfer ink from the printing plates or anilox cylinder to the printing surface in the printing machine.
- Features: They rotate with high precision, transferring ink to the printing plates.
- Printing Machine Rewinding System
- Function: The printed material is wound smoothly as it exits the printing machine and is turned into the final product.
- Features: Continuous winding during production allows for material to be produced at high speeds without being cut or damaged.
- Printing Station
- Function: Printing machines generally consist of multiple printing stations. Each station handles a specific ink color and printing job. Ink is transferred between stations and brought into contact with the material to be printed.
- Features: For multi-color prints, several printing stations may be used. Ensures proper mixing of colors and flawless printing.
- Oven or Temperature Control System
- Function: Controls the drying temperature of the ink during printing. Typically uses hot air ovens to rapidly dry water-based inks.
- Features: Different ink types require different temperature settings, so the oven system should be adjustable.
- Printing Price and Paint Change System
- Function: Used to quickly change printing color and ink. This system provides significant time savings for large production runs.
- Features: Machines are not stopped during the color change process, and the printing line is quickly adapted.
Flexographic printing machines are equipped with various equipment to improve print quality and ensure efficiency. Each piece of equipment has a specific function and ensures the smooth operation of the entire system. These equipments may vary depending on the type of printing material, printing speed, and the desired outcome.
