In commercial terms, this is called "Intaglio" [1] (TIL! I only knew the Germany word). While there are lots of printing techniques which are interesting in their details, I always have a special place for this one in my heart. :-D The sheer size of the printing cylinders (at least in most applications), the enormous speeds those machines run with and the effort that goes into producing the printing cylinders in the first place is just impressive. Intaglio is also very versatile, though it only makes sense for larger runs, due to the work beforehand.
