An ink cup for a pad printer has a hollow body and a surface that contacts a die plate on the pad printer, the contact surface being formed from bronze. In a preferred embodiment, the bronze used to form the contact surface of the ink cup is a copper alloy consisting of 83% copper, 7% lead, 7% tin, and 3% zinc. The ink cup has a flange between the hollow body of the cup and the contact surface. The ink cup flange, which extends outward from the hollow body, has a curved outer surface. A retaining ring having a diameter greater than that of the ink cup flange, has a curved inner surface adapted for receiving the ink cup flange to maintain the ink cup in contact with the die plate while permitting the ink cup to rock within the retaining ring.
