Abstract (en)

The invention provides a printing apparatus and a printing method. The printing apparatus comprises a first print head comprising a number n of first nozzles for discharging ink to a substrate transported through the printing apparatus in a transport direction, wherein the first nozzles are indexed by an index i=1...n. It further comprises a second print head comprising an equal number n of second nozzles for discharging ink to the substrate, wherein the second nozzles are indexed by an index j=1...n. The second print head is arranged parallel to the first print head. A control unit is configured to control a first nozzle i and a second nozzle j to discharge ink on a substrate position (P) in a single pass. Herein the second print head is shifted in a parallel direction to the first print head such that j = i + k, wherein k is an integer unequal to zero.
