Abstract:
A nozzle plate for a droplet ejection head, the nozzle plate comprising a first row of nozzles arranged to deposit droplets onto a deposition media; wherein the first row of nozzles extends in a row direction and comprises two or more nozzle clusters, each nozzle cluster being arranged along the row direction for a cluster length c, and extending along a cluster depth direction perpendicular to the row direction by a cluster depth d; wherein each nozzle cluster comprises a plurality of nozzles of which one or more nozzles within each nozzle cluster define the cluster length c and two or more nozzles within each nozzle cluster define the cluster depth d; wherein each nozzle cluster is spaced apart from an adjacent nozzle cluster along the row direction by a cluster spacing a such that an air flow path is created for forced air to pass through the row of nozzles in a controlled manner; and wherein, when the first row is projected in a transverse direction onto the row direction, a transition region between adjacent nozzle clusters comprises two or more nozzles from a first cluster and two or more nozzles from a second cluster, the second cluster being adjacent to the first cluster, and the nozzles in the transition region being equidistantly spaced from one another by a projected nozzle spacing.
