### Surface Reflectivity

Generally, surfaces with a matte finish work better than those with a glossy finish. A glossy surface finish usually has directional reflection. Depending on the angle of the light, you will get too much or too little light. You might even get a ‘hot spot’ (something that looks like a ‘blob’ in the graphics display area). This blob is actually the image of the light source. The reflection of light might add some extraneous points to the scan line, but the rest of the points will not be affected by the reflection. You can compensate for surface reflectivity by spraying the part with an aerosol powder or paint.
