A print pad for printing on a concave surface is molded to the forward surface of a cylindrical base. The base has a cavity therein and at least one hole extending from the forward surface thereof to the cavity. The print pad is made by filling a female mold with liquid polymer and positioning the forward surface of the base against the rear of the mold. Excess liquid polymer from the mold flows through the hole and into the cavity. As the polymer cures it contracts and draws liquefied polymer out of the cavity so that the cured print pad is not deformed.
