Abstract
A method of printing with a multi-nozzle continuous ink jet printer 1 that has a row of nozzles through which respective streams of ink 3 are emitted before being broken up into columns of droplets, a charge electrode assembly has a plurality of charge electrodes for charging individual droplets in each of the columns of droplets, deflection electrodes 5, 6 for deflecting charged droplets according to the charge thereon and an auxiliary charge electrode 8. A compensating charge is applied to all droplets in a chosen row by the auxiliary charge electrode causing differential deflection that allows drops from adjacent rows of droplets printed in alignment rather than offset from one another.
