Abstract
Systems and methods for industrial printing, e.g., using drop-on-demand (DOD) inkjet print heads, include, in at least one aspect, a printing device including: a print head configured to selectively eject liquid through nozzles to form an image on a moving substrate; and a printhead enclosure configured to contain a pressurized airspace at least in front of the nozzles; wherein the printhead enclosure includes a slot that aligns with the nozzles to allow the selectively ejected liquid to pass through the slot when the selectively ejected liquid is ejected toward the moving substrate; and wherein the printhead enclosure is configured to contain the pressurized airspace and cause airflow through the slot at a flow rate that prevents dust and debris from entering the slot while the selectively ejected liquid passes through the slot and the airflow without a direction of the selectively ejected liquid being impeded by the airflow.
