A document feeder is provided for presenting documents to the platen of a copier for copying with a vacuum belt platen transport system having document transporting belts movable under a substantially planar vaccum plenum backing. Also included is a vacuum system for applying a partial vacuum to a document sheet being transported by the movable belts over the platen. Show-through and show-around problems are reduced by optically mtching the belts and the plenum backing. In the preferred embodiment, the background surface is slightly roughend and made to be approximately 92% reflective to light during image exposure. The belts are composed of a urethane material which is approximately 16% transmissive but provides a 91% reflectance when moving along the plenum surface.
