turvatrükk

Turvatrükk, often translated as security printing, refers to the specialized techniques and technologies used to protect documents and valuables from counterfeiting and alteration. This broad field encompasses a range of anti-counterfeiting measures that can be applied to various substrates, including paper, plastic, and metal. The primary goal of turvatrükk is to make it difficult and expensive for unauthorized individuals to replicate or tamper with sensitive items.

Common methods employed in turvatrükk include the use of special inks, such as those that change color or are invisible under certain light conditions. Intaglio printing, which creates raised ink, is another prevalent technique, providing a tactile security feature. Microprinting, where text is so small it appears as a line to the naked eye but is legible under magnification, is also a widely used method. Holograms, watermarks, and security threads embedded within the substrate are other effective deterrents.

The application of turvatrükk is diverse, extending to various essential documents like banknotes, passports, identity cards, visas, and certificates. It is also utilized for high-value goods, tickets, and other items where authenticity and integrity are paramount. The continuous evolution of printing technology and detection methods means that turvatrükk is a constantly developing field, with new security features being introduced to stay ahead of counterfeiters. The effectiveness of turvatrükk relies on a combination of visible, covert, and forensic security features that can be verified by both the public and authorities.
