Abstract

A gravure printing press includes an inking device comprising a substantially closed ink duct for containing ink under pressure. The duct is defined by the surface (6) carrying the gravure image, a first trailing doctor blade (41), a sealing member (11) and end seals (7). The duct is divided into a first pressure zone (15) and a second non-pressure zone (16) by a second doctor blade (12) intermediate the sealing member (11) and the first doctor blade (41). Ink is supplied to the duct via the first zone (15) and is removed from the duct via the second zone (16).
