Offsettrükkides

Offsettrükkides is a term that refers to offset printing processes. Offset printing is a widely used printing technique where the inked image is transferred from a plate to a rubber blanket, and then to the printing surface. This indirect method is known for its high quality and is suitable for large print runs.

The principle behind offset printing is based on the immiscibility of oil and water. An image is created on a metal plate, with image areas made of a greasy material that attracts ink and non-image areas made of a material that attracts water. When the plate is dampened with water, the water adheres to the non-image areas, repelling the ink. The ink then adheres only to the image areas.

This inked image is then transferred to a rubber blanket cylinder. From the blanket cylinder, the image is finally pressed onto the paper or other substrate. This process is called offset because the image is not transferred directly from the plate to the paper.

Offset printing is highly versatile and can be used for a wide range of printed materials, including books, magazines, brochures, posters, and packaging. It is known for its sharp and clear image reproduction, consistent color quality, and ability to print on various types of paper and materials. The process is typically carried out using large, automated printing presses that can achieve high production speeds.
