Trockenprägung

Trockenprägung, also known as dry embossing, is a finishing process used to create raised or recessed designs on paper, cardstock, or similar substrates without the application of ink or glue. The technique relies on applying pressure with a die or stamp, often through a roller system, to impart a textured pattern or lettering. Because the process does not introduce moisture or chemicals, it is considered environmentally friendlier than traditional hot stamping or embossing methods that may involve inks or adhesives.

The origins of Trockenprägung date back to the early 20th century, when German printing companies sought efficient ways to add depth to packaging and stationery. The method found particular popularity in the packaging industry, where it is used to produce decorative, tactile surfaces on boxes and packaging inserts. It has also been employed in the printing of high‑value documents, such as passports and certificates, as a security feature, and in the creation of artistic graphics for books and calendars.

Unlike wet embossing, which uses ink or water to raise the paper, Trockenprägung requires precise regulation of pressure and die temperature. Materials used are typically dry papers, coated boards, or synthetic films. The process is compatible with high-speed production lines and can be combined with other printing processes, such as flexography or gravure, to create hybrid documents. However, because the raised surface is formed solely by mechanical deformation, the tactile quality may be less pronounced than in wet embossing, and resistance to wear can be lower if the paper lacks a protective coating.

Despite these limitations, Trockenprägung remains a popular technique for producing durable, high‑contrast decorative effects on a wide variety of printed products.
