Embossing

Dry embossing is a technology that does not use ink. To obtain the desired impression, a pre-prepared cliche is used, which is pressed to the respective material. There are two types of dry embossing - convex and concave. The convex embossing is most often used for pressing paper and cardboard, and it has two clichés - male and female or negative and positive, which are pressed against the material to obtain the desired convex imprint. In the case of the concave embossing, only one cliche is used, which is pressed against the respective material only from the upper side. In general, dry embossing resembles hot (gold) printing technology, with the difference that it does not use foil. Dry embossing is also called embossing, due to the convex or concave images that are obtained. The depth of the relief can vary, depending on the desired end effect and the strength of the applied pressure. In many cases, embossing is combined with hot stamping. Often used in combination with hot stamping, the convex embossing changes the surface of the media by giving a three-dimensional or raised effect to the selected locations. In general, the convex embossing is most often used to attract attention and achieve a quality contrast with the surrounding design of the product.

In many cases of practice, embossing is combined with hot stamping, but also with offset printing.
