  • Patent number: 6092464
    Abstract: A method of screen printing raised three-dimensional images, for example, corporate logos, on printable textile and/or non-textile substrates involves the use of a stencil attached to the print side of the print screen. The stencil is made from a pre-fabricated, photosensitive thick film having a precision controlled thickness. The print screen is coated with a photosensitive emulsion, and the combination of the print screen and the attached photosensitive stencil blank are exposed to UV light from metal halide lamps to harden the non-exposed emulsion and stencil material. The screen and stencil are thereafter washed to remove the non-hardened emulsion and stencil material, thereby creating openings in the screen coating and stencil material to form a three-dimensional image volume. Pigmented paste is screen printed through the one or more image openings in the coated screen and the associated one or more image volumes in the stencil to form a three-dimensional image on the substrate.
