VELOPLAST MACHINERY Produce Advance Technology Flexographic printing machinery, often referred to as flexo presses or flexo printers, are widely used in the packaging industry for printing onto various substrates such as paper, cardboard, plastic films, and flexible packaging materials. Flexo printing is a versatile and cost-effective printing process that is commonly used for producing labels, flexible packaging, corrugated boxes, and other printed materials.

Here are the key components and features of flexographic printing machinery:

1. Printing Stations: Flexo presses consist of multiple printing stations, each equipped with a printing cylinder, anilox roll, plate cylinder, ink system, and doctor blade. These stations can vary in number depending on the specific press configuration and printing requirements.

2. Anilox Roll: Anilox rolls are engraved with a pattern of cells that transfer a precise volume of ink to the printing plate. They play a crucial role in controlling ink delivery and maintaining consistent print quality.

3. Plate Cylinder: The plate cylinder holds the printing plate, which carries the image or design to be printed. Flexo printing plates are typically made of rubber or photopolymer materials and are flexible, allowing them to conform to the substrate’s surface.

4. Ink System: Flexo presses use liquid inks, which are transferred from the ink reservoirs to the printing plates via the anilox rolls. The ink system includes components such as ink pumps, ink chambers, and doctor blades to control ink flow and ensure uniform coverage.

5. Drying System: After printing, the ink must be dried quickly to prevent smudging and ensure adhesion to the substrate. Flexo presses may incorporate various drying methods, including hot air dryers, UV curing lamps, or infrared systems, depending on the ink and substrate being used.

6. Web Handling System: Flexo presses feature a web handling system that transports the substrate through the printing stations at a controlled speed. This system includes components such as tension control devices, web guides, and web cleaners to ensure smooth and precise substrate movement.

7. Register Control: Register control systems help maintain accurate registration between the different colors or printing stations, ensuring that the printed images align correctly. These systems may use sensors, cameras, or mechanical adjustments to monitor and adjust registration during printing.

8. Automation and Control: Modern flexo presses often feature advanced automation and control systems that allow for quick job setup, precise color matching, and real-time monitoring of print quality. This improves efficiency, reduces waste, and enhances overall productivity.

VELOPLAST Machinery Flexographic printing machinery comes in various configurations and sizes to accommodate different printing requirements and production volumes. Whether for narrow-web label printing or wide-web flexible packaging, flexo presses offer versatility, high-speed performance, and excellent print quality, making them a popular choice for many printing applications in the packaging industry.
