  • Screen printing stencil production
    Patent number: 6634289
    Abstract: Screen printing stencils are produced by a positive-working method which involves no light-sensitive materials and does not require the use of safe lights. A coated receptor film having a coating layer and a support layer is imaged using an ink-jet printer or plotter in areas corresponding to the open stencil areas. The film is then applied to a mesh and an emulsion applied. Chemical hardening of the emulsion takes place in the non-imaged areas. The stencil is then produced by removing the support layer of the film and washing away the unhardened emulsion. The receptor film may include a layer which is incorporated into the stencil layer to form a profile. In addition to screen production methods, coated films, coating compositions and compositions for imagewise application are disclosed.
