Abstract
In a method and a printing device for influencing an optical property of a varnish layer to be applied onto a printed recording medium, a coating substance is applied onto the recording medium by digital printing before the printing of at least one color separation of the print image on said recording medium. The quantity of the coating substance applied per area unit may be adjusted depending on the desired optical property of the varnish layer to be applied later.
