摘要：
The object of the invention is a method consisting in the use of hydrodynamic or pneumatic spraying for the application of a scented printing material on any chosen field of a moving printing substrate (9) and is implemented by means of hydrodynamic spray nozzles (8) as hydrodynamic spraying or by means of pneumatic spray nozzles (26) as pneumatic spraying. The object of the invention is also a device for selective spray application of the scented printing material, consisting of an application head (6) in which the hydrodynamic spray nozzles (8) or the pneumatic spray nozzles (26) are mounted. The device consists of a tank (1) for the scented printing material with a circulation pump (2) which, in the hydrodynamic spraying variant, is connected to a high-pressure positive displacement pump (3) supplied, from the network, with compressed air having a pressure adjustable by means of an electrically-controlled reducing valve (4), wherein the high-pressure pump (3) is connected through a high- pressure pipe (5)
