Banding means you see a shift in color and or reflectivity, and is almost always due to improper overlapping of rows when painting.
Orange peel results from too heavily applied coats, and coats following each other too soon. Also, too heavily applied coats that do not overlap enough (65-70%) serves to really accentuate "Banding".
If the material is pulled taunt, then give it at least two rounds of light sanding, using long sweeping strokes that....overlap at the edges. Then apply two very light Dusters with the required 70% overlap and you should be back to where you need / deserve to be.
