Patent number: 9427975Abstract: A method for improving durability of aqueous ink deposited on a substrate having multivalent metal salt present at the surface of the substrate is disclosed. The method includes depositing aqueous ink on the surface of the substrate, wherein the aqueous ink is an anionically stabilized pigment ink, drying the substrate to substantially remove the water from the deposited aqueous ink, applying substantially pure water and heat to the dried substrate with deposited aqueous ink, and removing the applied water and heat to return the dried substrate to an ambient temperature and moisture content. The applied substantially pure water and heat are sufficient to cause a significant improvement of the durability of the deposited ink on the substrate.Type: GrantFiled: June 12, 2014Date of Patent: August 30, 2016Assignee: EASTMAN KODAK COMPANYInventors: Douglas Eugene Bugner, David D.

Patent number: 8824948Abstract: In one aspect a method for operating a printer is provided in which a toner image is formed on a receiver using a toner having a polymeric binder and a wax. A contact surface is used to apply heat and pressure to heat the toner at least to a glass transition temperature for the toner and to heat the wax to at least an incorporated melting temperature. The toner image is allowed to cool below a glass transition temperature of the toner to form a fused toner image having a viewing surface and the wax is allowed to cool below the melting temperature for the wax so that after cooling the viewing surface has first portions with wax globules and second portions without wax globules. The viewing surface is wiped to move at least some of the wax from the wax globules in the first portions onto the second portions.Type: GrantFiled: September 30, 2011Date of Patent: September 2, 2014Assignee: Eastman Kodak CompanyInventors: James Stephen Honan, David D.
