ABSTRACT:
Provided are a stencil printing method and an apparatus therefor, in which a master having a low stiffness such as a single film may be transferred, in which a complicated mechanism for fitting and removing a plate is not needed and in which a degree of avoiding movement of a pressing roller to be in contact with the master can be minimized. The printing method and apparatus are characterized in that a perforated thermoplastic resin film is fed from a feeding roller and is brought into contact with an ink permeable sheet mounted under a tension for constituting a printing surface, in that a printing paper is superposed on the film, in that an ink roller having a printing ink from an inking section disposed on a surface of the ink permeable sheet opposite the film is displaced relative to the ink permeable sheet and the film while being maintained in rolling contact with the ink permeable sheet, thereby to perform the printing, and in that the ink permeable sheet, the film and the inking section are thereafter returned to their print starting state.
