  • High Printing Quality: Flexo presses provide precise control over ink transfer, registration, and color consistency, resulting in sharp, vibrant, and high-resolution prints.
  • Speed and Efficiency: Unit-type flexo presses are known for their high production speeds and quick setup times.
  • Cost-Effectiveness: Flexo printing is generally considered a cost-effective solution for medium to high-volume printing.
  • Wide Substrate Compatibility: Unit-type flexo presses are compatible with a variety of substrates, allowing for printing on different materials.
  • Environmentally Friendly: Flexo printing has made significant strides in reducing environmental impact.
  • Inline Finishing Options: Unit-type flexo presses can be equipped with various inline finishing options, reducing production time and costs.
  • Continuous Innovation: Unit-type flexo presses benefit from ongoing advancements in technology, allowing printers to stay competitive and meet market demands.

Working Principle of Unit-Type Flexo Press

The unit-type flexo press consists of several key components that work together to transfer ink onto the printing substrate:

  1. Plate Cylinder: The plate cylinder has a flexible printing plate attached to it, which holds the image or artwork to be printed.
  2. Inking System: Anilox rollers transfer ink to the plate cylinder, consisting of an ink fountain, doctor blade, and anilox roller.
  3. Impression Cylinder: The impression cylinder receives the substrate to be printed and presses it against the plate cylinder to transfer ink.
  4. Drying System: After the ink is transferred to the substrate, a drying system is employed to evaporate solvents or cure the ink.
  5. Repeatable Units: Unit-type flexo presses are designed with repeatable units, which can be combined to achieve multi-color printing.

Applications of Unit-Type Flexo Press

Unit-type flexo presses are suitable for various printing applications:

  1. Flexible Packaging: Suitable for printing on plastic films and laminates used in food packaging, pouches, bags, wrappers, and labels.
  2. Corrugated Packaging: Widely employed for printing on corrugated cardboard used in packaging boxes and containers.
  3. Labels and Tags: Preferred for printing labels and tags used in various industries, including retail, logistics, and manufacturing.
  4. Folding Cartons: Utilized for printing on folding cartons used in the packaging of consumer goods, cosmetics, pharmaceuticals, and other products.
  5. Paper Products: Suitable for printing on a wide range of paper products, including newspapers, magazines, catalogs, books, and stationery.
