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.
Claims33
A system comprising:
- a print head including multiple nozzles formed in a bottom surface of the print head, the nozzles configured to eject a liquid onto a substrate;
- and
- 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 in a direction corresponding to a motion of the substrate relative to the print head, the gas flow module including a vacuum manifold having a width in a direction perpendicular to the direction of motion of the substrate relative to the print head is greater than a width of the print head in the direction of motion of the substrate relative to the print head,
- in which a fluid resistance under the print head is less than a fluid resistance under the gas flow module.

A system comprising:
- a print bar configured to receive multiple print heads, the print heads configured to print a liquid onto a substrate;
- and
- a gas flow module configured to provide a flow of gas through a gap between a bottom surface of each print head and the substrate in a direction corresponding to a motion of the substrate relative to the print head, the gas flow module including a vacuum manifold having a width in a direction perpendicular to the direction of motion of the substrate relative to the print head is greater than a width of the print bar in the direction of motion of the substrate relative to the print head,
- in which a fluid resistance under the print bar is less than a fluid resistance under the gas flow module.
