What are the Different Types of Prepress Workflows Used in a Unit-Type Flexo Press?

A unit-type flexo press is a printing press used in the flexographic printing process. It is designed with modular units that can be combined and configured according to specific printing requirements. Each unit of the press consists of various components, such as a plate cylinder, anilox roller, inking system, and impression cylinder, which work together to transfer ink onto the printing substrate.

Advantages of a Unit-Type Flexo Press

  • Versatility: Unit-type flexo presses offer great flexibility and versatility in printing applications.
  • High Printing Quality: Flexo presses provide precise control over ink transfer, registration, and color consistency.
  • Speed and Efficiency: Unit-type flexo presses are known for their high production speeds and quick setup times.
  • Cost-Effectiveness: Flexo printing, including unit-type flexo presses, 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, expanding the range of applications and market opportunities.
  • Environmentally Friendly: Flexo printing, including unit-type flexo presses, 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: The flexographic printing industry is continuously evolving, with ongoing advancements in technology, materials, and processes.

How a Unit-Type Flexo Press Works

  1. Plate Cylinder: The unit-type flexo press has a plate cylinder with a flexible printing plate attached to it.
  2. Inking System: Anilox rollers transfer ink to the plate cylinder.
  3. Impression Cylinder: The impression cylinder receives the substrate to be printed.
  4. Drying System: 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.
