Abstract
A simulated clay tennis surface has a first region tufted with synthetic ribbons of a first height, and a second region tufted with synthetic ribbons higher than those of the first region. A granular infill material is applied to a depth which covers the ribbons in the first region, but leaves the tips of the ribbons of the second region visible to form court markings of a contrasting color to the infill material.
