Abstract

A golf club head having a laser-generated features to create contrast on the club face of the golf club head. The club face includes a central region, a toe region, and a heel region. The central region includes a first plurality of laser-generated features that provide a height-intersection coverage of the central region, a width-intersection coverage of the central region, and a surface-area coverage of the central region. The toe region includes a second plurality of laser-generated features that provide a height-intersection coverage of the toe region, a width-intersection coverage of the toe region, and a surface-area coverage of the toe region. The heel region includes a third plurality of laser-generated features that provide a height-intersection coverage of the heel region, a width-intersection coverage of the heel region, and a surface-area coverage of the heel region.
