  • Patent number: 6615720
    Abstract: A brayer ball, used in a brayer that is a hand-operated ink-stamping device of small size used for making proofs, is disclosed. This brayer ball consists of a spherical solid or hollow core body, and a ball cover formed on the spherical core body and having an external pattern consisting of a variety of letters, figures and/or characters. The brayer ball smoothly rolls on a target sheet in any desired direction without being limited in its rolling direction during a stamping process. This brayer ball thus prevents a stamped pattern from being distorted, deformed, or undesirably, partially faint or broken.
