FIELD: printing.
SUBSTANCE: method and device for applying a colorant onto a continuously moving substrate in the form of first and second transverse parts is implemented by equipping with the printing carriage having a first set of inkjet print heads and a second set of inkjet print heads. The carriage is moved transversely along the substrate in the forward pass, applying the first and second parts by means of the first and second plurality of inkjet print heads, respectively, and is subsequently moved along the substrate in the reverse pass. The first and second sets of inkjet print heads are set so that the first and second parts complement to each other both in the forward and the return path to provide generally complete coverage of the substrate.
EFFECT: parts which complement to each other can be applied by one print head.
