Unit-type Flexo Press Ink Supply System

A unit-type flexo press is a modular printing press used in the flexographic printing process, consisting of various components, such as a plate cylinder, anilox roller, inking system, and impression cylinder. In this article, we will explore the advantages, working principles, applications, and maintenance of the unit-type flexo press, as well as introduce EVER-POWER, a professional manufacturer of flexo presses.

Advantages of Unit-type Flexo Press

Versatility

Unit-type flexo presses offer great flexibility and versatility in printing applications due to their modular design. They can be customized and configured for specific printing processes, substrates, and colors, making them 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 and 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 Principles of Unit-type Flexo Press

The unit-type flexo press consists of various components that work together to transfer ink onto the printing substrate. Here is an overview of the working 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. The units can be adjusted and synchronized to ensure accurate registration and color consistency.

Applications of Unit-type Flexo Press

Unit-type flexo presses are widely used in various industries and products, including:

Flexible Packaging

Unit-type flexo presses are commonly used for printing on flexible packaging materials, such as plastic films and laminates. They are suitable for applications like food packaging, pouches, bags, wrappers, and labels.

Corrugated Packaging

Flexo presses are widely employed for printing on corrugated cardboard used in packaging boxes and containers. Unit-type flexo presses can handle the large format and high-volume requirements of the corrugated packaging industry.

Labels and Tags

Flexo presses are preferred for printing labels and tags used in various industries, including retail, logistics, and manufacturing. Unit-type flexo presses enable high-quality, durable, and customizable printing on different label materials.

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. They offer efficient production speeds and excellent print quality for intricate designs and vibrant colors.

Paper Products

Flexo presses are suitable for printing on a wide range of paper products, including newspapers, magazines, catalogs, books, and stationery. Unit-type flexo presses can handle high-speed printing and large print volumes required in the paper industry.
