Abstract (en)
[origin: EP1208991A2] Method of colour printing with an ink jet printer having a printhead (10) which is reciprocatingly moved in forward and return scan passes in a main scanning direction (X), in which an even number of nozzle arrays (C1, M1, Y1; Y2, M2, C2) is provided for each of at least two colours, and said nozzles arrays are symmetrically arranged in the main scanning direction (X), characterized in that, for printing a single pixel (P; P2; P3; Q) composed of at least two colours with high density, ink dots (30, 32, 34, 36) of each of these colours are formed in even numbers by activating the corresponding nozzles (22) of the symmetrically arranged arrays at appropriate timings in the same scan pass of the printhead (14). <IMAGE>
