Title: Innovations in Screen Printing: The Contributions of John William Jones
Introduction
John William Jones, an innovative inventor based in Wantage, GB, has made significant contributions to the field of screen printing. With a total of three patents to his name, Jones is known for his cutting-edge methods that enhance stencil production processes.
Latest Patents
Among his latest inventions, Jones has developed a method for screen printing stencil production which utilizes a unique positive-working method that does not involve light-sensitive materials. His approach allows the production of screen printing stencils using a coated receptor film that is imaged with an ink-jet printer or plotter. After imaging the film, a mesh is applied, followed by the application of emulsion. The non-imaged areas undergo chemical hardening, allowing for the removal of the unhardened emulsion and yielding effective stencils. Additionally, he has created a coated film product that features a stencil-forming layer made from a blend of two grades of polyvinyl alcohol. This method not only streamlines the production process but also enhances the adhesion of the stencil layer to the screen mesh.
