Abstract
Inkjet printing methods are described that create a combination of higher resistance flow areas and lower resistance flow areas to allow a vaporized carrier fluid reducing airflow to flow between a printing module and a receiver without disrupting inkjet drop placements. Removal of the vaporized carrier fluid reduces condensation.
Claims21
A printing method comprising:
- providing a cross-module air flow between barrier and a receiver;
- creating higher resistance flow areas between the barrier and the receiver having a higher resistance to the cross-module airflow than is found in lower resistance airflow channels between the higher resistance flow areas, the barrier and the receiver;
- directing droplets of an ink having a vaporizable carrier fluid to pass from the inkjet printheads to the receiver through the higher resistance flow areas;
- and
- wherein the cross module airflow removes at least some of any vaporized carrier fluid from between the barrier and the receiver and wherein the higher resistance to the cross-module airflow in the higher resistance flow areas causes the cross-module airflow to flow through the lower resistance airflow channels without creating airflows in the higher resistance flow areas that cause variations in the travel paths of the ink droplets that are sufficient to form an artifact in a print made on the receiver using the ink droplets.
