Claims78
A method of applying a protective overcoat to a surface of a printed transparency, the method comprising:
- applying heat and pressure to a donor web having a carrier side comprising carrier ribbon material and a transfer side comprising protective overcoat material, wherein the heat and pressure facilitate release of a section of the transfer side from adhering to the carrier side of the donor web and facilitate transfer of the section of the transfer side to adhering to the surface of the transparency.
A donor web providing a protective overcoat to a printed transparency, the donor web having:
- a) a carrier side comprising a carrier ribbon layer and a lubricant layer as an exterior layer preventing wear of a surface of a heating element or pressing element, the surface coming in contact with the carrier side of the donor web;
- b) a transfer side comprising a protective overcoat material, a release layer as an interior layer adjacent to the carrier side, the release layer facilitating release of the transfer side from the carrier side;
- and an adhesive layer as an exterior layer of the transfer side, the adhesive layer enhancing adhering of a section of the transfer side to form the protective overcoat on the printed transparency.
An apparatus comprising a donor web having a carrier side comprising carrier ribbon material and a transfer side comprising protective overcoat material, a means of applying a protective overcoat to at least one surface of a printed transparency, by applying heat and pressure to the donor web, wherein the heat and pressure facilitate release of a section of the transfer side from adhering to the carrier side of the donor web and facilitate transfer of the section of the transfer side to adhering to the surface of the printed transparency.
