Abstract
A system includes a print head including multiple nozzles formed in a bottom surface of the print head. The nozzles are configured to eject a liquid onto a substrate. The system includes a gas flow module configured to provide a flow of gas through a gap between the bottom surface of the print head and the substrate. The gas flow module can include one or more gas nozzles configured to inject gas into the gap. The gas flow module can be configured to apply a suction to the gap.
Claims16
A method comprising:
- providing a flow of gas through a gap between a bottom surface of a print head and a substrate in a direction corresponding to a motion of the substrate relative to the print head, including:
- controlling, by a flow control device distinct from the print head, one or more of a velocity and a uniformity of the flow of gas through the gap;
- and
- ejecting a liquid from a nozzle formed in the bottom surface of the print head, including ejecting the liquid through the gap and onto the substrate.
