  • Patent number: 4853706
    Abstract: A method of making a color transparency with jetted color ink jet apparatus includes the steps of heating hot melt ink including an ink vehicle and a substantially translucent dye to a temperature above the melting point to attain the liquid state, ejecting small volumes of the hot melt ink from the ink jet apparatus toward a substantially transparent resinous support, cooling the small volumes of ink on the support so as to attain the solid state, and flattening the small volumes on the support to produce a substantially planar surface which minimizes refraction and scattering of light projected thereon or therethrough.
