    Abstract: For the formation of colored pixels on a substrate, a print head can be used which performs a forward and return movement in relation to the substrate and which has a number of ink nozzles, in which the different ink nozzles can produce ink droplets of different colors. A print head which, in the direction of the first movement, comprises at least two parallel rows of at least two ink nozzles can be used. Preceding the printing step the printing method comprises the step of entailing the allocation in each case of two neighboring colors in a color space to ink nozzles of different rows, and black either to one or more ink nozzles of a separate row or to the first ink nozzle and last ink nozzle of the same row.
