Abstract

A method of printing an halftone image by a liquid droplet generator (100), having at a first location in a manifold of the generator a liquid-sedimentation with highest density and having two inlets and; wherein the part is determined for displacing the liquid-sedimentation to a second location in the manifold by using a printmask (1000), having a width and height, which divides for a selected printing period the plurality of nozzles in minimum three sequential zones between the first inlet (516) and second inlet (517) comprising minimal for printing the determined part: a first zone (1001) at the first inlet (516) wherein the printmask (1000) determines that N1% of the part the nozzles in the first zone (1001) are used; and a second zone (1002) at the middle of the first inlet (516) and second inlet (517) wherein the printmask (1000) determines that N2% of the part the nozzles in the second zone (1002) are used; and a third zone (1003) at the second inlet (517) wherein the printmask (1000) determines that N3% of the part the nozzles in the third zone (1003) are used; whereby 100 >= N1 > N2 > N3 >= 0
