Flexo Press Plate Cylinder Refurbishment Quality Assurance

A unit-type flexo press is a type of 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 and Features

Versatility

Unit-type flexo presses offer great flexibility and versatility in printing applications. The modular design allows for easy customization and configuration of the press based on the desired printing process, substrate, and colors required. This adaptability makes it suitable for a wide range of industries and products.

High Printing Quality

Flexo presses have made significant advancements in recent years, achieving excellent print quality comparable to other printing methods. The unit-type flexo press provides 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. They can handle rapid printing tasks, making them suitable for large-scale printing operations. Additionally, quick setup times and fast changeovers between jobs contribute to improved efficiency and reduced downtime.

Cost-Effectiveness

Flexo printing, including unit-type flexo presses, is generally considered a cost-effective solution for medium to high-volume printing. The presses utilize flexible printing plates, which are more affordable compared to other plate types. Additionally, the ability to print on a wide range of substrates reduces the need for additional printing processes, resulting in cost savings.

Wide Substrate Compatibility

Unit-type flexo presses are compatible with a variety of substrates, including paper, cardboard, films, labels, and flexible packaging materials. This versatility allows for printing on different materials, 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. Water-based and UV-curable inks are commonly used, which have lower volatile organic compound (VOC) emissions compared to traditional solvent-based inks. Additionally, advancements in energy-efficient drying systems contribute to sustainability efforts.

Inline Finishing Options

Unit-type flexo presses can be equipped with various inline finishing options, such as laminating, die-cutting, embossing, and varnishing. This eliminates the need for separate post-printing processes, reducing production time and costs.

Continuous Innovation

The flexographic printing industry is continuously evolving, with ongoing advancements in technology, materials, and processes. Unit-type flexo presses benefit from these innovations, allowing printers to stay competitive and meet the changing demands of the market.

Working Principle

  1. Plate Cylinder: The unit-type flexo press has a plate cylinder with a flexible printing plate attached to it. The plate cylinder holds the image or artwork to be printed.
  2. Inking System: Anilox rollers transfer ink to the plate cylinder. The inking system consists of an ink fountain, doctor blade, and anilox roller. The doctor blade ensures an even layer of ink is applied to the anilox roller, which then transfers the ink to the plate cylinder.
  3. Impression Cylinder: The impression cylinder receives the substrate to be printed. It presses the substrate against the plate cylinder, allowing the ink from the plate to transfer onto the substrate.
  4. Drying System: After the ink is transferred to the substrate, a drying system is employed to evaporate solvents or cure the ink. Drying can be achieved through various methods, such as heated air, UV lamps, or infrared radiation.
  5. Repeatable Units: Unit-type flexo presses are designed with repeatable units, which can be combined to achieve multi-color printing. Each unit consists of a plate cylinder, anilox roller, inking system, and impression cylinder. The units can be adjusted and synchronized to ensure accurate registration and color consistency.

Applications

Unit-type flexo presses are widely used in the following industries:

  • Flexible Packaging: food packaging, pouches, bags, wrappers, and labels
  • Corrugated Packaging: packaging boxes and containers
  • Labels and Tags: retail, logistics, and manufacturing
