Embossing

Embossing, mechanical reproduction, by pressure, of designs and patterns in relief on various materials, such as metal, leather, fabrics, cardboard, and paper. The process involves passing the material between suitable dies or plates that impress the design from the back. Fabrics are embossed by passing them between copper cylinders, one engraved with the design, the other covered with felt and acting as the countercylinder, providing enough pressure to force the fabric into the hollows of the die-cylinder.
