Flexo Press Plate Cylinder Lubrication

Introduction

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

1. Versatility: Unit-type flexo presses offer great flexibility and versatility in printing applications.
2. High Printing Quality: Flexo presses have made significant advancements in recent years, achieving excellent print quality comparable to other printing methods.
3. Speed and Efficiency: Unit-type flexo presses are known for their high production speeds.
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: Flexo printing, including unit-type flexo presses, has made significant strides in reducing environmental impact.
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.

Working Principle

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: After the ink is transferred to the substrate, 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.

Applications

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.

Possible Issues and Solutions

1. Ink Smearing or Blurring:

Ensure proper ink viscosity and consistency. Adjust the doctor blade pressure to achieve a clean and even ink transfer. Verify that the anilox roller is clean and free from dried ink or debris. Check for excessive plate wear or damage and replace if necessary. Optimize drying parameters to ensure proper ink curing.

2. Registration Issues:

Verify that all mechanical adjustments, such as gear settings and tension controls, are properly calibrated. Check for worn or damaged gears, cylinders, or rollers and replace as needed. Ensure the plate cylinder and substrate tension are correctly set. Align the printing plates accurately and securely on the plate cylinder. Regularly clean and maintain the registration sensors and control systems.
