PURPOSE:To make it possible to observe a picture pattern as a punched pattern from front and back surfaces, by forming a metal vapor deposition layer to the outside of a transparent synthetic resin film having a picture pattern printed thereon and printing a picture pattern on the outside of said layer by utilizing a register mark before washing off the exposed vapor-deposited metal. CONSTITUTION:A picture pattern is printed on a transparent synthetic resin film and a metal vapor deposition layer is formed to the outside thereof so as to leave a register mark at the time of printing and a picture pattern is printed on the outside thereof by utilizing the register mark and, thereafter, the exposed vapor-deposited metal is washed off. In this case, because picture pattern layer printed at first is covered with the metal vapor deposition layer but the register mark is not covered with said vapor deposition layer, the picture pattern can be printed on the outside of the vapor deposition layer so as to be allowed to coincide with the first picture or to be fitted thereto. The second time printing of the picture pattern allows the metal vapor deposition layer to expose at the part other than the picture pattern and, therefore, if the surface is washed by fluoric acid or caustic soda, the exposed metal vapor deposition layer is released but the metal vapor deposition layer covered with the picture pattern remains in a state guarded by printing ink. |
