This high-quality, but not widely used, printing process is similar to gravure printing. Ink is applied to a machine or hand-engraved stamp and is then passed over a wiping paper so that the ink is retained only in the deep printing areas. Paper is then pressed into the embossing stamp at high pressure and the ink is transferred to the surface in a relief-like manner. The embossing can also be seen on the reverse of the substrate. This makes it possible to distinguish between a "real steel engraving" from an industrially produced relief print. If the back-facing emboss is not desired, for example in the case of double-sided business card, two pre-printed papers are laminated together.
