<p>Both an inkjet printer and method are provided for contone inkjet printing on a receiver. The inkjet printer (10) includes a printhead (12) having at least one nozzle (18) for ejecting a stream of ink droplets, a droplet deflector (15) for generating a flow of gas that impinges on the stream of ejected droplets to deflect the trajectories of the droplets, and a controller (40, 44, 48, 50, 52, 54, 56, 64, 68, 70) for varying the velocity of the gas flow in order to vary the degree of trajectory deflection so the droplets intended to print on a particular pixel in the receiver land on top of one another without elongation despite relative movement between the printhead and the receiver. The printer provides improved image quality and productivity while reducing image artifacts. <IMAGE></p> |
