<p>A stencil or printing sheet (8a) having sufficient resistance against ambient condition and preservation ability and capable of providing a desirable printing quality even at an initial printing. The stencil sheet may include a thermoplastic film (25), an adhesive layer (26), an ink holding layer (27) and an ink impermeable film (28). The ink holding layer is sealingly covered by the thermoplastic film at one surface and the ink impermeable film at another surface. In other words, each of the ink holding layers (27) is enveloped by the thermoplastic film and the ink impermeable film. Thus, ink retained in the ink holding layer is sealingly maintained by these films. In use, the thermoplastic film is formed with a perforated image and is arranged to face a sheet to be printed. The upper ink impermeable film is then depressed to cause ink from the ink holding layer to ooze through the perforations of the lower thermoplastic film toward the sheet to be printed. <IMAGE></p> |
