How Gravure Printing Works

Gravure printing operates on a set of basic principles and mechanics that distinguish it from other printing methods. The process involves transferring ink from an engraved cylinder to the printing substrate, typically paper, plastic, or foil. Here’s a detailed look at how gravure printing works, the key components involved, and the significance of the gravure printing cylinder.

Basic Principles and Mechanics

At its core, gravure printing is an intaglio process, meaning the image to be printed is engraved below the surface of the printing plate or cylinder. The key steps in the gravure printing process include:

1. Engraving the Cylinder: The image to be printed is engraved onto a copper gravure printing cylinder. This engraving can be done using a diamond-tipped stylus or laser engraving techniques. The engraved areas, known as cells, vary in depth and size to control the amount of ink they hold.
2. Inking the Cylinder: The engraved cylinder is immersed in an ink fountain, which fills the cells with ink. The excess ink on the surface of the cylinder is then wiped off using a doctor blade, leaving ink only in the recessed cells.
3. Transferring the Ink: The ink-filled cylinder rotates and comes into contact with the substrate (paper, plastic, etc.) under pressure. The ink from the cells is transferred onto the substrate, forming the printed image.
4. Drying: After the ink is transferred, the substrate passes through a drying unit to evaporate the solvent from the ink, leaving behind a dry, printed image.
5. Rewinding: Finally, the printed substrate is rewound into a roll for further processing or finishing.

Key Components of a Gravure Press

A gravure press consists of several essential components that work together to produce high-quality prints. These include:

1. Gravure Cylinder: The core component that carries the engraved image. It is usually made of copper and can be electroplated with chromium for durability.
2. Ink Fountain: A reservoir that holds the ink and applies it to the gravure printing cylinder.
3. Doctor Blade: A metal blade that scrapes excess ink off the surface of the gravure cylinder, ensuring that only the ink in the engraved cells is transferred to the substrate.
4. Impression Roller: A rubber-covered roller that presses the substrate against the gravure cylinder to facilitate ink transfer.
5. Drying Unit: Typically, an array of heaters or infrared lamps that dry the printed substrate.
6. Rewinder: A mechanism that rewinds the printed substrate into a roll for subsequent processing.

The Gravure Cylinder: Engraving Process and Significance

The quality of the print is directly influenced by the precision and quality of the engraving on the cylinder. Here’s a closer look at the engraving process and its significance:
