<p>Method and apparatus (14, 104) for continuous inkjet printing wherein a first continuous stream of ink droplets (66) traveling above a first flow path (48) is used as a mask for colliding with a second continuous stream of ink droplets (70, 72) traveling along an second, intersecting flow path (56) en route to a receiver (12) on which an image is to be printed. Selective droplets (72) of the second droplet stream are timed and of a size to pass between and avoid the masking droplets (66) of the first droplet stream so as to travel on and impinge the receiver (12) for forming the image thereon. The colliding masking and masked droplets (66, 70) are larger than the selected printing droplets (72) to facilitate collision. The smaller printing droplets (72) facilitate sharp pixel formation. <IMAGE></p> |
