Richard J. Kapusniak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5633116
    Abstract: A prepress color proof can be prepared using suitable donor elements and an intermediate receiver element that has a roughened outer image receiving layer so that the color image is transferred with high image resolution. The intermediate receiver element can also have a cushioning layer beneath the outer image receiving layer that reduces the tendency for entrapped dirt particles to form minus density spot defects. In addition, a unique carrier plate can be used to carry the donor and intermediate receiver elements through laminating equipment. This carrier plate has a thermoplastic adhesive layer with sufficient tackiness to prevent irreversible dimensional change during lamination.

  • Patent number: 5374497
    Abstract: A print-out layer is incorporated in a donor element that is useful in a dry color proofing process in which a colored image is transferred from the donor element to a receiver. To achieve full color reproduction, images are transferred in succession and in register, to the receiver from donor elements, respectively containing yellow, magenta, cyan and black colorants. A visible image is formed in the print-out layer as a result of imagewise exposure of the donor element to activating radiation and is utilized to facilitate visual registration in forming the multicolor image on the receiver.

  • Patent number: 5279933
    Abstract: A high-contrast room-light-handleable black-and-white silver halide photographic element that is especially useful in the field of graphic arts is comprised of a support, an imaging layer containing doped silver halide grains with a mean grain size of less than 0.12 micrometers, and a print-out layer containing doped silver halide grains with a mean grain size in the range of from 0.14 to 0.4 micrometers. The element utilizes very slow speed emulsions which render it capable of being handled in room light and is able to print-out a visible image on normal exposure and develop to full density upon being processed in conventional developing solutions.

  • Patent number: 5104777
    Abstract: A high-contrast room-light-handleable black-and-white photographic element is comprised of a support having on one side thereof a silver halide emulsion layer and having, on the same side of the support as the silver halide emulsion layer, both a filter dye layer in which the dye is immobile and a matte layer comprised of a matting agent dispersed in a hydrophilic colloid that serves as a binder. In this element, the filter dye layer serves to provide uniform filtering of incident light, while the matte layer provides a rough surface which facilitates rapid vacuum draw-down during contact exposure.
