Abstract
Variation in colour intensity when printing areas of a surface (13) by a jet printing technique is achieved by (a) varying the voltage increment of the ramp incremental voltage applied to the droplet charging electrode (12) of a jet printer, and (b) simultaneously varying the spacing between consecutive droplet scans of the jet printer. In this way, a uniform matrix of equi-spaced droplets is printed over the area of the surface (13) and striated or non-uniform colour intensity in the printed area is avoided.
