Abstract:
1. An inkjet printing system comprising: a receiver transport system having an actuator that moves a receiver in a direction of receiver movement past a plurality of printheads arranged to direct droplets of an ink having a vaporizable carrier fluid to the receiver; a barrier between the printheads; and a plurality of caps with each cap positioned about one of the inkjet printheads and extending from the barrier toward the receiver to create higher resistance flow areas between the cap and the receiver with each cap having at least one opening through which the droplets of ink can pass from the plurality of printheads through the higher resistance flow areas to the receiver with the caps being separated to create lower resistance air flow channels between the caps, the barrier, and the receiver, through which a cross-module airflow can flow around the higher resistance flow areas; wherein the caps have deflection surfaces that extend from a common vertex and are shaped to direct the cross-module airflow air into the lower resistance airflow channels and through which the cross-module air flow can flow past a print line without creating flows into the higher resistance flow areas that create an artifact in a print made using ink droplets; and wherein the print line extends across a width direction that is not perpendicular to a direction of receiver movement, further comprising at one end of the print line, a cap having one side without an adjacent cap, and a side flow control structure shaping the airflow on the one side of the cap without an adjacent cap in a manner that is similar with the airflow on the other side of the cap with an adjacent cap.
