  • Patent number: 6869650
    Abstract: The present invention is drawn to the thermal transfer overcoating of images printed on porous media, and methods of overcoating images printed on porous media. Upon use of the systems and methods of the present invention, a thermally coated print is generated that can comprise a porous media substrate having printed thereon a digitally produced image. The digitally produced image and the porous media substrate is thermally coated by an adhesive protective layer, wherein the adhesive protective layer has a tangent d that is greater than 1 and melt viscosity less than 1×105 Pa.·sec. as applied above its phase transition temperature. Thus, the voids in the porous media substrate can be substantially filled, and further, substantially no tags remain on the print.

  • Patent number: 6793988
    Abstract: An image transcription method of transcribing an image of the dye on a printing sheet outputted by e.g., a video printer onto a substrate for transcription, such as a cup of pottery or the like. For transcription, a resin is coated on the surface of the substrate for transcription to form a reception layer. This reception layer is dried in an electrical oven to form a support for transcription. A printing sheet carrying an image of a sublimable dye is stacked on the reception layer of the support for transcription and pressured to the reception layer under application of heat and pressure. As the resin for the reception layer, the acrylic resin or the epoxy resin or both are employed. If the resin composed mainly of the acrylic resin is employed, the viscosity of the resin is set to 43 to 52 seconds in terms of the Ford cup viscosity, and the resin discharge pressure from a spray gun is set to 35 kg/m2±0.01 kg.cm2.
