Abstract
A method for jetting color ink includes determining an initial voltage value of a nozzle, wherein the initial voltage value corresponds to a predetermined jetting volume of the nozzle; determining a maximum adjusting voltage value of the nozzle, wherein the maximum adjusting voltage value may correspond to an allowable error value of the predetermined jetting volume; combining the initial voltage value with an adjusting voltage value to obtain a jetting voltage, wherein the adjusting voltage value may be randomly selected between zero to the maximum adjusting voltage value; and jetting the color ink from the nozzle according to the jetting voltage onto a sub-pixel in a pixel.
