ABSTRACT:
A single configuration presentation folder is provided, enabling a user to heat laminate custom printed sheets to the face of the folder without the use of a conventional paper carrier. Portions of the folder are scored to produce folders with one or two pouches holding sales literature or pouchless versions for stand-up displays, or folders containing saddle-stitched data sheets therein or laminated data sheets mounted within a loose leaf or spiral bound cover. Various arrays of fiducials are provided for enabling easy, accurate manual positioning of variable sized insert sheets with respect to the folder edges. The fiducials may be made to disappear upon lamination or are otherwise visually non-obtrusive to the eye. The fiducials may consist of disappearing ink, readily releasable adhesive, grid lines formed in the heat activatable adhesive of the cover sheet, indentations in the folder or inks having low visual contrast. Warpage is prevented by the use of a special plastic backing sheet and a secured file using carbonless paper thwarts fraudulent compromise of critical data therein.
