Abstract:
A method for reducing sequence striations on a printed article, comprising the steps of:selecting a pattern of energizing plate electrodes and associated nib groups according to any combination of variables comprising:(a) the number of lines arranged in a pattern in a direction of travel of the article, wherein the pattern includes a minimum of 4 lines;(b) the number of sets of lines in the pattern;(c) the starting position of a firing sequence order of plate electrodes and associated nib groups in one line in the pattern compared to adjacent lines in the pattern;(d) the firing sequence order of plate electrodes and associated nib groups within a single line in the pattern;(e) the variation in direction of firing of the firing sequence order of plate electrodes and associated nib groups within a single line in the pattern compared to adjacent lines in the pattern; and(f) the number of printing colors having the same variables; andenergizing the plate electrodes and associated nib groups according to the pattern.
