In this way, color gradations in the resulting print image 09 can be realized without changing a number of drops contributing to the print image 09 (amplitude modulation). It is also possible to use at least one heating element per nozzle, which generates a gas bubble in a volume filled with ink at high speed by evaporation of printing ink. The extra volume of the gas bubble displaces ink, which in turn through the corresponding nozzle is ejected and forms at least one drop of ink.

In the drop-on-demand method, a drop deflection after ejection from the corresponding nozzle is not necessary since it is possible to set a target position of the respective ink droplet on the moving substrate web with respect to the circumferential direction of the at least one first central cylinder 201 solely by an emission timing of the respective one Drop of ink and a rotational speed of the first central cylinder 201 and / or determined by the rotational position of the first central cylinder 201.
