Tonertrükk

Tonertrükk refers to a printing technique that utilizes toner, a dry powder made of plastic particles, pigment, and a carrier, to produce images on paper. This method is most commonly associated with laser printers and photocopiers. In a laser printer, a laser beam selectively discharges a charged, photosensitive drum. Toner particles, which are electrostatically charged, adhere to the discharged areas of the drum. The toner is then transferred from the drum to the paper. Finally, the paper with the toner is passed through a fuser, where heat and pressure melt and fuse the toner particles into the paper, creating a permanent image.

The process is known for its speed and precision, making it suitable for high-volume printing and sharp text reproduction. Unlike inkjet printing, which uses liquid ink, toner printing is a dry process, meaning the print is not susceptible to smudging from moisture immediately after printing. The toner itself is typically composed of finely ground plastic polymers, carbon black (for black toner), or colored pigments. The precise composition can vary between manufacturers and toner types, influencing print quality and durability. Tonertrükk is a widely adopted technology in both home and office environments due to its efficiency and cost-effectiveness for many printing tasks.
