visible markings interposed between the polymer layer and the front surface of the substrate, the visible markings being visible through the polymer layer and comprising elongated score line markings;
wherein the substrate comprises a peripheral edge and the polymer layer overlays at least both the peripheral edge and the front surface of the substrate;
wherein said substrate comprises a heel portion and a toe portion and wherein the elongated score line grooves comprise a first set of plural elongated grooves extending into the polymer layer and positioned at least partially across the ball striking surface of the toe portion of the substrate and a second set of plural elongated grooves extending into the polymer layer and positioned at least partially across the ball striking surface of the heel portion of the substrate;
wherein the score line markings comprise a first set of plural score line markings extending at least partially across the toe portion of the substrate and second set of plural score line markings extending at least partially across the heel portion of the substrate;
wherein the first set of plural elongated grooves overlies and is substantially aligned with and spaced from the first set of score line markings and wherein the second set of plural elongated grooves overlies and is substantially aligned with and spaced from the second set of score line markings.

Abstract
A face insert for golf club head in one embodiment can comprise a substrate comprising a score line groove-free front surface. A cover layer is provided at least on the front surface of the substrate. The cover layer can alternatively overlay at least a portion of the peripheral edge of the substrate. The cover layer comprises a ball-striking surface spaced by the cover layer from the substrate. Plural elongated score line grooves can extend into the polymer layer from the ball-striking surface. In addition, visible markings are interposed between the cover layer and the front surface of the substrate, the visible markings being visible through the cover layer. In one form the visible markings comprise elongated score line markings and target markings in a central portion of the substrate. The visible markings can be screen-printed markings, which are then protected by the cover layer from wear. The cover layer can be molded and can be a polymer layer. The score line grooves can be formed, for example, by molding during molding of the polymer layer.
