Abstract
DOD ink delivery systems and methods are described herein that are used in DOD card printing systems of card processing systems for supplying ink for DOD printing on plastic cards. The ink delivery systems are configured to recirculate the ink without using a recirculation tank separate from an ink supply. The ink can be recirculated back into the ink supply or, when the ink supply is not present, the ink can be recirculated from a return header tank to a supply header tank.
