A method for embossing a container body (40) at a precise position includes the steps of: (a) providing a first reference mark (41) on a tubular wall of the container body (40); (b) rotating the container body (40) until the first reference mark (41) reaches a predetermined first angular position; (c) vertically moving the container body (40) to an embossing region (20) where the container body (40) is sleeved around an inner die assembly (21), and where an outer die assembly (22) is disposed outwardly of the container body (40) ; (d) placing the inner and outer die assemblies (21,22) at a position operative for embossing the container body (40); (e) embossing a pattern (43) on the container body (40) at a position (42) which is predetermined relative to the position of the first reference mark (41) through the inner and outer die assemblies (21,22); and (f) stopping at least one of the inner and outer die assemblies (21,22) at a predetermined second angular position.
