Embossing is the process of creating a three-dimensional image or design in paper. This is achieved by using a metal die (female) usually made of brass.

In printing it is used as an accent process and can be used in conjunction with ink called colour register embossing or with no ink called blind embossing. It also can be used with foil stamping which when embossed with foil is known as combination stamping or combo stamping. All of these processes use a die. Most types of paper and boards can be embossed.
