<p><P>PROBLEM TO BE SOLVED: To provide an inkjet printing system that independently control the mass and speed of ink liquid drops ejected from an inkjet print head. <P>SOLUTION: A taper angle 330 depends on relationships among an exit diameter 310, an inside diameter 315, and/or thickness 325. For example, when the thickness 325 is fixed, the taper angle 330 can get larger as the difference between the exit diameter 310 and the inside diameter 315 is increased. Likewise, when the thickness 325 is fixed, the taper angle 330 can get smaller as the difference between the exit diameter 310 and the inside diameter 315 is decreased. The different values of and adjustments among the exit diameter 310, the inside diameter 315, the thickness 325, and the taper angle 330 can dictate the mass and speed of ink liquid drops that exit the nozzle 305. Further, they can allow the mass and speed of liquid drops to be independently dictated by the exit diameter 310 and the taper angle 330, respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
