In a method for the formation with a print head on a substrate of pixels with a predefined pixel colour by means of droplet deposition, a print head is used which is set up so that, during operation, it performs in one pass a forward and return movement in relation to the substrate. The print head comprises ink nozzles which are aligned in a row behind one another in the direction of movement of the print head, which row comprises an initial series and a final series of ink nozzles, for at least two different first colours, and also a middle series of ink nozzles for at least two different additional colours, which additional colours cannot be formed from the first colours. The method comprises the steps of printing a pixel with a predefined pixel colour by the successive deposition of ink droplets of colours from the row of ink nozzles, in which black is composed as the first and/or the last colour with the aid of ink droplets of the first colours from the ink nozzles.
