PCT No. PCT/SE90/00729 Sec. 371 Date May 11, 1992 Sec. 102(e) Date May 11, 1992 PCT Filed Nov. 13, 1990 PCT Pub. No. WO91/07283 PCT Pub. Date May 30, 1991.The invention relates to a method of compensating for crosstalk between adjacent charging electrodes (14) in an ink jet printer having multiple printing jets (12) or channels, each with one charging electrode (14). In order to provide a desired drop charge in a specific channel X, there is applied, to the corresponding charging electrode (14X), a charge potential VX which is compensated for in response to (i) any charge potentials VX-1 and VX+1 applied to charging electrodes (14X-1, 14X+1) of the nearest channel X-1 and X+1, respectively, on each side of the specific channel X, and (ii) in response also to at least charge potentials VX-2 and VX+2 applied to charging electrodes (14X-2, 14X+2) of the next nearest channel X-2 and X+2, respectively, on each side of the specific channel X. The compensation is achieved by selecting VX as equalling a value V(I) associated with a charge situation I at issue and included in a matrix of compensated predetermined potential values compiled by an iterative, or equivalent, technique.
