Abstract: Method for forming glossy and matt surface zones during printing of a can body in a production line comprising: a priming varnishing machine for applying a priming layer to the can body, a printing machine for applying printing colors including at least one glossy printing color to the can body provided with a priming layer, and a finish varnishing machine for applying a finish varnish to the can body provided with a priming layer and printed. A matt varnish is applied as finish varnish, after drying of the inks, by means of a flexographic printing plate controlled by dot-for-dot marking or by means of a cylinder controlled by dot-for-dot marking, to the zones of the can body for the purposes of giving a matt visual aspect. To implement the method, a conventional production line can be re-equipped with simple means.
