Abstract
A method of operating for an ink jet printer having a printer head bearing a plurality of equi-distantly spaced ink jets for printing parallel lines of dots on a substrate in n passes of the print head over the substrate. Between each pass of the printer head over the substrate, the printer head is displaced in a direction perpendicular to the direction of the lines by a distance y that satisfies: (i) y=m.sub.1.times.a where m.sub.1 is a natural number equal to 2 or more and a is the separation gap between adjacent lines; (ii) y is not a multiple of the inter ink jet separation distance of the printer head; and (iii) m.sub.1 and n do not have a common factor except the factor with the value of 1. These conditions on y ensure that two adjacent lines are printed by different ink jets and that each line is printed by only one ink jet.
