Abstract
An arrangement employing multiple print heads displaced laterally for printing on a substrate moving relative to the arrangement in a given direction of relative motion has N print heads, where N is at least four, deployed sequentially along the direction of relative motion with a displacement X0 between adjacent print heads. The sequence of lateral offsets between successive print heads is chosen such that the maximum displacement measured parallel to the direction of relative motion between any two print heads which generate adjacent points in the printed output is no greater than (N/2)X0, and is preferably no greater than 2X0.
