METHOD FOR PRODUCING VARIOUS IDENTIFICATION CARDS PREVENTING FORGERY AND/OR FALSIFICATION

摘要

The method punches a card paper for the position of an identification picture by superimposing the picture on the paper to be pinched out together. The picture is separated from the punched paper and is placed back to fill exactly the punched opening to be covered with a thin transparent lamination film of a little larger in size than the picture. The card paper having the picture laminated is placed between two lamination films to be hot rolled under pressure for melt fusion for the final product. The thin lamination film covered over the picture includes a layer of a release agent under the top protective layer which separates from the other layers of printing and lamination over the picture upon application of heat to the card outer layer of lamination. The remaining other layers after separation are composed of materials which deform on heating to make impossible the removal of the picture against alteration of the card.
