ofsettrükki

Ofsettrükki, also known as offset printing, is a widely used printing technique that employs a series of plates to transfer ink onto paper. The process begins with the creation of a halftone screen, which is a grid of dots that represents the image or text to be printed. This screen is then used to create a metal plate, which is coated with a light-sensitive material. The plate is exposed to light through the halftone screen, creating a relief image on the plate's surface.

During the printing process, the inked plate presses against a rubber blanket, which in turn presses against the paper. The ink is transferred from the plate to the blanket and then to the paper, creating a high-quality, durable print. The paper is then passed through a series of rollers to remove any excess ink and dry the print.

Offset printing is known for its high print quality, durability, and versatility. It is commonly used for printing books, magazines, brochures, and other commercial materials. The technique allows for the production of large quantities of prints with consistent quality, making it an efficient and cost-effective option for many printing needs.
