Methods and devices for coating a composite substrate. A desired design can be applied to at least a portion of a substrate's one or more surfaces by indexing the substrate, a coating apparatus, or a combination thereof, during or between application of one or more contrast coatings. The term indexing refers to changing the position (e.g. angle, tilt) of the substrate and/or the coating apparatus, the speed of such positioning, the rate at which the coating is applied, or some combination thereof. By such indexing, the pattern (4A-C) applied to the substrate (2A-C) can be varied.
