A silk screen printing machine which includes an inking blade having a concave trowel configuration for more efficiently applying ink to a silk screen stencil, and a pressure roller which cooperates with a paper-carrying drum to force ink through the stencil onto paper carried by the drum. A solvent feeding porous wiper, which continuously feeds a cleaning solvent by capillary action, bears against the periphery of the pressure roller to clean residual ink from this roller after it has pressed ink through the silk screen onto the paper.
RELATED APPLICATIONS
This application is a continuation-in-part of my U.S. application Ser. No. 697,232 filed Jan. 11, 1968 now abandoned, entitled "Silk Screen Printing Machine."
The invention relates a source sheet for stencil printing comprising: a porous support material; a porous resin film formed on a surface of the porous support material; wherein, the porous support material has a maximum air permeability of 90 s/100 cc; and, the porous resin film has a maximum air permeability of 600 s/100 cc; preferably, the air permeability of the porous support material.ltoreq.the air permeability of the porous resin film. According to the source sheet and plate manufacturing method of the present invention, the plate for the stencil printing can be obtained which is superior in the pore block property and in which the thermal deformation of the source sheet during the plate manufacturing is suppressed.
