Abstract: Systems and methods of automatically bleeding air from a primary ink delivery system, so little or no air is mixed with the ink once it reaches a secondary ink system containing print heads. An air bleeder return assembly with a flow restrictor orifice that is configured to remove air from ink pumped to the carriage of print heads, thereby minimizing jet dropouts. Additionally, this setup provides the added advantage of the ability to run the bulk bags dry without ingesting large quantities of air to the ink delivery system.

Abstract: Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput, but the nozzles are arranged so that any given square inch of substrate to which ink is being applied receives a lower amount of ink. A longer effective print head is provided by arranging the print heads into a longer array, where the print heads are butted substantially end-to-end. As a result, the net throughput of the printer is the same as that of a conventional printer because the printer uses the same number of print heads, but the amount of ink that is applied to any given square inch is less on a pass.
