A card processing system, comprising: a card input that is configured to hold a plurality of plastic cards to be processed; a card output that is configured to hold a plurality of processed plastic cards; at least one of a magnetic stripe reading/writing system and an integrated circuit chip programming system between the card input and the card output; a drop-on-demand card printer between the card input and the card output that is configured to print on a plastic card using ultraviolet curable ink, the drop-on-demand card printer includes: at least one drop-on-demand print head (26, 26a-e); an ink bottle mounted in the drop-on-demand card printer and fluidly connected to the at least one drop-on-demand print head (26, 26a-e), the ink bottle containing ultraviolet curable ink, the ink bottle having a neck defining an ink outlet, and the neck having an exterior surface with threads thereon; a cap affixed to the neck of the ink bottle, the cap having a connection sleeve with an interior surface with threads thereon, and the threads on the interior surface of the connection sleeve are engaged with the threads on the exterior surface of the neck; a receiver that is configured to receive the cap when the ink bottle is mounted in the drop-on-demand card printer, the receiver having a quick-connect coupler; the cap includes a quick-connect valve that controls flow of the ultraviolet curable ink from the ink bottle through an ink passage in the cap, and the cap further includes a check valve adjacent to the quick-connect valve that provides venting by allowing air into the ink bottle through a vent passage in the cap, the quick-connect valve is connected with the quickconnect coupler of the receiver; and a manual release mechanism mounted in the drop-on-demand card printer that is engageable with the quick-connect coupler to permit manual release of the connection between the quick-connect valve and the quick-connect coupler; an ultraviolet curing station between the card input and the card output, the ultraviolet curing station is configured to cure ultraviolet curable ink applied to a plastic card (30 by the drop-on-demand card printer. a card input that is configured to hold a plurality of plastic cards to be processed;
