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=n1(c) and p=n2(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 d1, where d1=n3(s); printing a second set of z rows of subpixels with the printing head; repeating the printing steps for a total of n2 sets of z rows of subpixels. Variables include:
- c, an integer greater than 1;n1, n2, and n3 which are the same or different and are independently selected from integers greater than 0, with the proviso that n2 is not a multiple of c.
