| 20080290175 | Layer-built body having hidden barcode and figures thereof - A layer-built body having hidden barcodes and figures thereof is disclosed in the invention, so as to allow barcode scanning devices to read the barcodes, the layer-built body comprising: a lenticular lens sheet divided into a first surface and a second surface, and the first surface has a plurality of convex lens-shaped optical structures disposed thereon; a patterned layer printed with trademarks or figures, and divided into a plurality of striped images; and at least a barcode layer printed with information about barcodes and divided into a plurality of striped images. The striped images of the barcode layer are alternated with the striped images of the patterned layer to make a synthesized image layer, and are combined with the second surface of the lenticular lens sheet; wherein when a viewer looks at the layer-built body from an ordinary angle, the optical structures of the lenticular lens sheet allows the viewer to see contents of the patterned layer completely, and when the layer-built body is tilted at specific angles, the optical structures of the lenticular lens sheet allows barcode scanning devices to read contents of the barcode layer. Therefore, information about barcodes and figures may be provided on a fixed surface area simultaneously. | 11-27-2008 |
