Abstract
Abstract Transparency medium for automatic printers comprises transparent film sheet with central window area and surrounding margin area and a backer sheet bonded to the film sheet only in the margin area. Preferably, a sequence of such backer sheets, including side edges suitable for automatic feeding (such as by tractor pin holes) on a separate edge portion, are separably connected at adjoining forward and rearward edge lines to form a fan folded supply of indefinite length.
