What Are the Considerations for Selecting a Plate Cylinder Refurbishment Provider for a Unit-type Flexo Press?

A unit-type flexo press is a modular printing press that can be customized and configured based on specific printing requirements. Each unit of the press consists of various components that work together to transfer ink onto the substrate, with the plate cylinder being one of the critical components. When selecting a plate cylinder refurbishment provider for a unit-type flexo press, there are several factors to consider.

Basic Definitions and Product Features

A unit-type flexo press is designed with repeatable modular units that can be easily combined and configured to meet specific printing requirements. The press’s main components include a plate cylinder, anilox roller, inking system, and impression cylinder, which work together to transfer ink onto the substrate. This printing process is widely used in various industries, including flexible packaging, corrugated packaging, labels and tags, folding cartons, paper products, and more.

The unit-type flexo press has several advantages:

Versatility

The unit-type flexo press offers great flexibility and versatility in printing applications. The modular design allows easy customization and configuration of the press based on the desired printing process, substrate, and colors required.

High Printing Quality

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 and quick setup times, making them suitable for large-scale printing operations.

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.

Wide Substrate Compatibility

Unit-type flexo presses are compatible with a variety of substrates, including paper, cardboard, films, labels, and flexible packaging materials.

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.

Inline Finishing Options

Unit-type flexo presses can be equipped with various inline finishing options, such as laminating, die-cutting, embossing, and varnishing.

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 Principles

The unit-type flexo press works based on the following principles:

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.

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.

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.

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.

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.

Applications

The unit-type flexo press is suitable for various printing applications, including:

Flexible Packaging

Unit-type flexo presses are commonly used for printing on flexible packaging materials, such as plastic films and laminates.

Corrugated Packaging

Flexo presses are widely employed for printing on corrugated cardboard used in packaging boxes and containers.

Labels and Tags

Flexo presses are preferred for printing labels and tags used in various industries, including retail, logistics, and manufacturing.

Folding Cartons

Unit-type flexo presses are utilized for printing on folding cartons, commonly used in the packaging of consumer goods, cosmetics, pharmaceuticals, and other products.

Paper Products

Flexo presses are suitable for printing on a wide range of paper products, including newspapers, magazines, catalogs, books, and stationery.
