an application step of winding off the transparent resin film from the roll of the transparent resin film and applying an adhesive to the second surface of the transparent resin film;
a bonding step of bonding the second surface of the transparent resin film and the picture layer of each of the sheet printed matters with the adhesive and cutting the transparent resin film in front and at back of the sheet printed matters to obtain laminates; and
the bonding step involves stacking the laminates in a manner that the transparent resin film of a first laminate is in contact with the transparent resin film of a second laminate or the substrate of a first laminate is in contact with the substrate of a second laminate, and applying pressure to the laminates in a lamination direction.
