Fleksoinnin

Fleksoinnin, often referred to as flexo printing or flexography, is a modern printing technique that utilizes a flexible relief plate to transfer ink to a substrate. This method is a variation of letterpress printing and is highly versatile, capable of printing on a wide range of materials including plastic, metallic films, cellophane, and paper. The core of the flexo printing process is the flexographic plate, which is typically made of rubber or photopolymer. This plate has raised areas that carry the ink.

The printing unit consists of an ink fountain, a forme roller (anilox roll), a printing plate, and an impression cylinder. Ink is transferred from the fountain to the forme roller, which is a roller engraved with cells that hold a specific volume of ink. The forme roller then transfers a thin, uniform layer of ink to the raised image areas of the printing plate. As the substrate passes between the printing plate and the impression cylinder, ink is transferred from the plate to the substrate, creating the printed image.

Flexography is widely used for packaging applications, including labels, food packaging, flexible films, and corrugated cardboard. Its ability to print on non-absorbent materials and its high-speed capabilities make it an efficient choice for mass production. The technology has evolved significantly, offering improved print quality and a wider range of ink options, including water-based, solvent-based, and UV-curable inks.
