Abstract: A device is provided for imprinting a solid or dashed straight line on the surface of a golf ball. The device consists of a semi-rigid stencil that may be snapped securely around the surface of a golf ball. While the golf ball is allowed to rotated freely within the stencil so as to allow a user to rotate the ball to the correct position, a pair of finger grips are provided which, when compressed, clamp the ball in position so as to prevent the ball from rotating while the ball is being marked. The stencil also includes a linear groove adapted to receive a pen, indelible marker or other writing implement for marking the ball with a linear indicia. This indicia can be used for identification purposes, as a putting trainer, and an alignment aid during play. Beveled edges or bumpers may also be included along the inner surface of the groove to assist the user in imprinting the ball and prevent smudging or pooling of the ink or paint used to mark the ball.
