THERMO-SENSITIVE MATERIAL FOR STENCIL PRINTING FORMS FOR STENCIL PRINTING, METOD AND DEVICE FOR PRODUCTION OF THIS MATERIAL AND STENCIL PRINTING MACHINE Russian patent published in 2006 - IPC B41N1/24 

FIELD: technology for producing thermo-sensitive material for stencil printing forms, engineering of device for producing said material, engineering of stencil printing machines.

SUBSTANCE: material for printing forms is made only from film of thermo-plastic resin by usage of polyether film in such a way, that aperture, through which paint may permeate, can be thermally perforated without increasing power of thermo-printing head. Film is a thermo-sensitive material for stencil printing forms 12, having given thickness, and consists of stretched mylar film or stretched film with low melting point, produced by copolymerization of polyethylene therephthalate and polybutylene therephthalate. A set of smallest raster cells 14 is formed on one side of film by transfer of template. Transfer of template may be performed under working pressure 10⁴·10^2(m-t)/(m-g) Pascals or higher, when working temperature is t°C, melting point temperature of film is m(°C), and temperature of film vitrifying is g(°C).

EFFECT: decreased power of thermo-printing head, facilitated operations with film.
