Patent ID: 8720366

Claim:
A printing system comprising: at least one print-head; a housing comprising a sealable print-head chamber enclosing the at least one print head, the print-head chamber disposed between a sealable inlet chamber and a sealable outlet chamber, the print-head chamber configured to be sealed prior to deposition of a quantity of organic material onto the substrate; an inlet sealing partition and an outlet sealing partition disposed in communication with said print-head chamber, the sealing partitions adapted for receiving and dispatching the substrate, respectively; an inert gas input in communication with the print-head chamber, the inert gas input configured to provide an inert gas environment within the print-head chamber; a floatation system configured to floatingly support the substrate in and through the chambers, the floatation system comprising a plurality of fluid nozzles configured for floating support of the substrate via a plurality of inlet pressure ports and vacuum outlet ports while the print head delivers the quantity of organic material onto the substrate; and a controller in communication with the print head, the chambers, the partitions, and the floatation system, the controller configured to: operate the inlet sealing partition such that the substrate can be transported into the print-head chamber, energize the print-head to deposit the quantity of the material onto the substrate when the substrate is at a controlled height in the print-head chamber via control of pressure inlet and vacuum outlet ports of the floatation system, and operate the outlet sealing partition such that the substrate can be transported from the print-head chamber.
