1. A method for forming a surface acoustic wave touch device, the method comprising:
- forming a multi-layered material stack with a layer of opaque light reflective material over a layer of color material on a border region of a touch substrate; and
positioning a transducer and an acoustically reflective array over the layer of opaque light reflective material in a configuration to propagate surface acoustic waves on the multi-layered material stack and the touch substrate.

Abstract
Multi-layered paint on a border of a surface acoustic wave touch device may reduce attenuation. The touch substrate has a front surface and a back surface where the front surface has a touch region. Multi-layered paint is formed on the back surface to form a border along the touch substrate. The multi-layered paint includes a mirror layer and a color layer. The surface acoustic waves propagate over at least a portion of the border region such that the surface acoustic waves propagate on the multi-layered paint without excessive wave attenuation.
