A unit-type flexo press is a versatile printing press that can be customized according to specific printing requirements. With modular units and automated ink supply systems, it offers numerous advantages over other printing methods. In this article, we will discuss the considerations for selecting a unit-type flexo press with automated ink supply systems.

Basic Definition and Product Features

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.

The advantages of a unit-type flexo press with automated ink supply systems include:

1. 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.
2. 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.
3. 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.
4. Cost-Effectiveness – Flexo printing, including unit-type flexo presses, is generally considered a cost-effective solution for medium to high-volume printing.
5. Wide Substrate Compatibility – Unit-type flexo presses are compatible with a variety of substrates, including paper, cardboard, films, labels, and flexible packaging materials.
6. Environmentally Friendly – Water-based and UV-curable inks are commonly used, which have lower VOC emissions compared to traditional solvent-based inks. Additionally, advancements in energy-efficient drying systems contribute to sustainability efforts.
7. Inline Finishing Options – Unit-type flexo presses can be equipped with various inline finishing options, such as laminating, die-cutting, embossing, and varnishing.
8. 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

The working principle of a unit-type flexo press with automated ink supply systems involves the following steps:

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 with automated ink supply systems are used in a variety of industries and applications, including:

1. Flexible Packaging – Unit-type flexo presses are commonly used for printing on flexible packaging materials, such as plastic films and laminates.
2. Corrugated Packaging – Flexo presses are widely employed for printing on corrugated cardboard used in packaging boxes and containers.
3. Labels and Tags – Flexo presses are preferred for printing labels and tags used in various industries, including retail, logistics, and manufacturing.
4. 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.
5. Paper Products – Flexo presses are suitable for printing on a wide range of paper products, including newspapers, magazines, catalogs, books, and stationery.
