Abstract
There is provided a method of printing a regular array of rows of subpixels on a workpiece. The subpixels have c different colors and have a subpixel pitch s. A printing head has z nozzles arranged in a row with a spacing p, where z=n(c) and p=(c−1)(s), the printhead being at a first position relative to the workpiece. There are c different printing inks, one for each of the c colors, and each of the printing inks is supplied to the nozzles in a regular alternating pattern. The method includes steps of printing a first set of z rows of subpixels with the printing head; moving the workpiece laterally relative to the printing head by a distance d, where d=z(s); printing a second set of z rows of subpixels with the printing head; repeating the printing steps ntimes for a total of n+2 sets of z rows of subpixels. Variables include:
