Abstract
There is provided a method of forming a regular array of rows of subpixels on a workpiece. The subpixels have c different colors, where a colors are formed by printing. The subpixel pitch is s. The method includes (a) providing a printing head having a sets of z adjacent nozzles arranged in a row, wherein the spacing between adjacent nozzles within the same set is p=cs and the spacing between adjacent nozzles in different sets is p=(c+1)s, the printing head being at a first position relative to the workpiece; (b) providing a different printing inks, one for each of the a colors; (c) supplying each of the printing inks to the nozzles such that each of the nozzles within a set receive the same color and a different color is supplied to each set of nozzles; (d) printing a first set of az rows of subpixels with the printing head; (e) moving the workpiece laterally relative to the printing head by a distance d, where d=cz(s); (f) printing a second set of az rows of subpixels with the printing head; and (g) repeating steps (e) and (f) n−2 times for a total of n sets of az rows of subpixels. In the process, a, c, n, and z are independently integers greater than 1.
