Abstract: A plate for a print head assembly includes a plurality of nozzles passing therethrough, and includes first and second sides, the first side having a raised perimeter defining a seat. Each of the nozzles also includes a flange extending from the seat. A print head assembly includes: a print head having a plurality of hose connectors; at least one detachable plate having a plurality of nozzles passing therethrough; and a plurality of hoses connecting said at least one plate to the print head. The nozzles each include first and second ends, the first end extending from the first side of the plate and have a chamfered periphery, which is configured to be received in an opening of an ink tank of a print head assembly. The second end includes a frustoconical tapered end, which is configured to be connected to a hose that connects to the print head.
