A colorant dispenser may be moved to a first position of a first dot in the first set. A pre-determined amount of colorant may be applied to the first position. A measured blast of air may modify coverage and profile of the applied colorant. The dispenser may then move to the remaining positions until all dots of the first color and subsequent sets of dots of subsequent colors are dispensed.

A laminated nozzle assembly includes a first end plate having first and second fluid inlets, a second end plate, and a plurality of nozzle plates positioned between the first and second end plates. A first fluid conduit is fluidically connected to the first fluid inlet. The first fluid conduit has a reservoir and one or more first openings. A second fluid conduit is fluidically connected to the second fluid inlet. The second fluid conduit has an inlet channel, a connecting channel and one or more second openings. An orifice assembly includes a first orifice fluidically connected to the first opening and a second orifice fluidically connected to the second opening. The first and second orifices are disposed in the same plate of the plurality of nozzle plates and are coplanar.

The disclosure relates to an application device for applying an application agent (e.g. heat-conducting paste) into a cavity, in particular in a battery module of an electric battery. The application device according to the disclosure comprises a nozzle for dispensing the application agent through the nozzle and a first pressure sensor for measuring a first pressure reading (p.sub.A, p.sub.B) of the application agent upstream of the nozzle.
