A ring or coil binder with the rings or spirals mounted between opposed cover panels each of which is formed from three or four folded and adhered layers of a blank of sheet material having an image printed on up to 100 percent of the surface area of a plastic coated surface thereof using dye sublimation printing. For the ring folder the opposed inner end surfaces of the cover panels abut each on the underneath or adjacent to the plurality of rings or coil and wherein the image is visible on up to 100 percent of the surface area of the inside and outside surfaces of the cover. For the coil bound book the opposed inner surface of the cover panels have opposed abutting articulated end flaps adjacent the spine with perforations therein to receive a coil, wherein on of the articulated end flaps is articulated above the spine by an articulated intermediate flap which extends from one of the opposed inner surfaces of the cover panels.
