"Офортна преса" (as in the answer of colleague Emilia Delibasheva) is the term for intaglio printing devices for the fine arts field. These are relatively simple, hand-operated presses used by intaglio artists to print small series of their works – which is exactly the case here.

"Дълбокопечатна машина" (mentioned below by colleague Klyunchev) is the term for a commercial gravure printing press. The printing principle is the same, only commercial presses are typically complex, automated, high-speed printing machines where the image carrier is a printing cylinder rather than a plate.
