A wrinkle-reduction system includes two media guiding rollers located in proximity to first and second edges of a media, each media guiding roller having a corresponding roller axis and having one or more grooves formed around its exterior surface. The media travels along a transport path past the media-guiding rollers with a first side of the media facing the exterior surface of the web-guiding rollers. Air sources provide an air flow into the grooves in the media-guiding rollers, the air flow being directed between the first side of the media and the exterior surface of the media-guiding rollers thereby producing a Bernoulli force to draw the media toward the media-guiding rollers. The first roller axis is not parallel to the second roller axis such that when the air sources are activated the media guiding rollers impart a lateral stretching force to the media in the cross-track direction.
