sügavtrükisilindrid

Sügavtrükisilindrid are specialized cylinders used in the gravure printing process. Gravure, also known as intaglio printing, is a method where the image to be printed is etched or engraved into the surface of a cylinder. This creates recessed cells that hold the ink.

The manufacturing of sügavtrükisilindrid is a precise and multi-step process. First, a base cylinder, typically made of steel, is prepared. A layer of copper is then electroplated onto the steel core. This copper layer is the material that will be engraved with the image. The thickness and consistency of the copper plating are critical for the quality of the final print.

Once the copper layer is applied, the image is transferred to the cylinder. This can be done through various methods, including mechanical engraving, chemical etching, or laser engraving. Mechanical engraving involves physically cutting the cells into the copper using a diamond stylus. Chemical etching uses a resist to protect certain areas while acid corrodes the exposed copper, creating the cells. Laser engraving offers high precision and is increasingly common.

After the cells are engraved, the cylinder is often chrome-plated. This hard chrome layer protects the softer copper from wear during the high-speed printing process, extending the cylinder's lifespan and ensuring consistent print quality over long runs. The depth and shape of the engraved cells determine the amount of ink transferred to the substrate, thereby controlling the tonal values and color intensity of the printed image. Sügavtrükisilindrid are essential components for producing high-quality, detailed prints found in publications, packaging, and decorative laminates.
