According to the present invention there are provided method and apparatus for producing a simple printing plate having open cells, which method and apparatus area simple in construction and permit accurate and continuous production of the printing plate. More specifically, as the method there is provided a method of producing a simple printing plate having open cells by pressing both an embossing member having a relief image and a to-be-embossed member which is a sheet having open cells, in a heated state of the embossing member, allowing the relief image to be transferred to the to-be-embossed member, characterized in that the embossing member is attached to an embossing cylinder, the to-be-embossed member is attached to a to-be-embossed cylinder, one or both of the embossing cylinder and the to-be-embossed cylinder being in an arcuate form, and both cylinders are rotated in synchronism with each other, thereby pressing the embossing member and the to-be-embossed member in a rolling fashion.

Apparatus for producing simple printing plate having open cells

A method for producing a printing plate which involves forming an image on the surface of a sheet having open cells by selectively applying a thermal exposure to the surface of the sheet. The sheet is a thermoplastic resin preferably having melting point between about 50.degree. to 150.degree. C. The resulting printing plate has a planar surface with no relief sections; instead there are porous and nonporous sections, with the porous sections being permeable to ink infused within the printing plate. A method of printing using the above plate is also disclosed.
