In a stiched, continuous stream type ink jet printer with a reciprocating carriage, one significant tolerance affecting spacing between droplets from adjacent nozzles as they impact the paper, is the throw distance. By throw distance, it is meant that distance between the nozzle and the paper. Several dimensional tolerances will vary the throw distance as the carriage traverses across the paper. For example, varying thickness of the paper, the varying platen diameter along its axis, the platen axis eccentricity as the platen rotates, etc.
