A method for minimizing cross-contamination of print cartridges in an inkjet printing system due to aerosol drift by employing a bi-directional spitting scheme coupled with a configuration of the print cartridges. The method includes a carriage for traversing across a print medium and a spittoon, the carriage having a plurality of N receptacles, the receptacles identified from left to right as positions 1 through N, includes mounting a reactive print cartridge in either positions 1 and N, or both, on the carriage, the reactive print cartridges having a plurality of nozzles for ejecting reactive droplets and mounting a plurality of print cartridges in the remaining positions on the carriage, the print cartridges having a plurality of nozzles for ejecting ink droplets. During operation of the printing system, depending on the number of reactive print cartridges and the number of print cartridges and the location thereof, intermittently ejecting non-printing ink and reactive droplets from the print cartridges in a specific order while the carriage is moving in a transverse left to right direction and ejecting ink and reactive droplets from the print cartridges in a specific order while the carriage is moving in a transverse right to left direction.
