Abstract
Sharp, endless sleeves for rotary screen printing having superior durability to printing can be obtained by a method of the present invention. According to this method, a metal image-forming layer having a smooth endless outside surface and a thickness in the range of 5-50.mu. is made, and into the inside thereof is inserted a cylindrical screen sleeve as an image-supporter made of a metal or a non-metallic material having been processed to provide electric conductivity thereto, and both the layers and the sleeve are fixed to each other with electro- or chemical- plating, or on the outside of a cylindrical screen sleeve, is formed a smooth surface of endless image-forming layer by plating while partly coating the screen-sleeve.
Claims8
A method for producing a rotary printing screen, comprising the steps of :
- inserting a metal screen sleeve image supporter made by a plating process into the inside of a metal cylinder;
- and
- immersing both said screen sleeve and said metal cylinder in a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
A method for producing a rotary printing screen comprising the steps of:
- inserting a metal screen sleeve image supporter made by a plating process into the inside of a non-metal cylinder, said non-metal cylinder having a conductive inside surface produced by a chemical plating process;
- and
- immersing both said screen sleeve and said non-metal cylinder into a plating bath in order to coat said screen sleeve with a plated metal and simultaneously to form an image-forming layer.
A method for producing a rotary printing screen, comprising the steps of:
- forming a metal image-forming layer on an inside surface of a metal cylinder, said layer being a smooth, endless outside surface of a cylindrical member having a thickness in the range of from 5 to 50 microns;
- inserting within said metal cylinder a cylindrical screen sleeve image supporter, said sleeve being comprised of a metal;
- and
- fixing said cylindrical member and said sleeve together by an electroplating process.
