Patent number: 9463642Abstract: A method for printing an image with authentication features, including: printing a media treatment material onto a print medium in accordance with a pattern of predefined authentication features, and printing one or more visible printing materials onto the print medium in accordance with an image pattern, thereby providing a printed visible image. The media treatment material alters an interaction between the visible printing materials and the print medium so that characteristics of the interaction, such as printing material penetration characteristics, are different in image regions where the media treatment material was printed than in image regions where the media treatment material was not printed. The difference in the characteristics of the interaction between the one or more visible printing materials and the print medium causes the pattern of authentication features to be detectable.Type: GrantFiled: July 29, 2015Date of Patent: October 11, 2016Assignee: EASTMAN KODAK COMPANYInventors: Michael J. Piatt, Terry Anthony Wozniak, James A. Katerberg, Wayne Lee Cook, Douglas Eugene Bugner, Allan Francis Sowinski

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. Putnam, Hwei-Ling Yau, Thomas Joseph Dannhauser, Brian L Lindstrom

Patent number: 9376582Abstract: A method of printing with water-based inkjet inks on a water-impermeable, low-surface-energy substrate, includes: a) modifying surface properties of the substrate to increase the surface energy; b) coating the modified surface of the substrate with a first layer comprising a colorless water-based tie-layer composition; c) coating over the first layer with a second layer including a colorless and transparent water-based ink-receptive composition including: i) a water-soluble multivalent metal salt; and ii) a hydrophilic binder polymer; d) depositing directly on the surface of the second layer one or more water-based ink compositions containing an anionically stabilized pigment colorant, wherein the one or more water-based ink compositions are deposited in a predetermined pattern with an inkjet deposition system in response to electrical signals; and e) drying the first and second coated layers and the deposited inks to substantially remove the water.Type: GrantFiled: July 30, 2015Date of Patent: June 28, 2016Assignee: EASTMAN KODAK COMPANYInventors: Thomas Joseph Dannhauser, Douglas Eugene Bugner, David D.

Patent number: 9375949Abstract: A method for printing an image with authentication features, including: printing a media treatment material onto a print medium in accordance with a pattern of predefined authentication features, and printing one or more visible printing materials onto the print medium in accordance with an image pattern, thereby providing a printed visible image. The media treatment material alters lateral spreading characteristics of the visible printing materials within the print medium, so that the lateral spreading characteristics are different in image regions where the media treatment material was printed than in image regions where the media treatment material was not printed. The difference in the lateral spreading characteristics causes the pattern of authentication features to be detectable.Type: GrantFiled: July 29, 2015Date of Patent: June 28, 2016Assignee: EASTMAN KODAK COMPANYInventors: Michael J.

Patent number: 8398223Abstract: A process for printing an image includes printing a substrate with an aqueous inkjet ink and drying the printed image with a near-infrared drying system, wherein the inkjet ink is a yellow or magenta inkjet ink and comprises a yellow or magenta colorant and a distinct near-infrared absorbing compound. Inkjet ink sets for use with an inkjet printing system employing a near-infrared drying system in the process include at least a black ink and a yellow ink, wherein the yellow ink comprises a yellow colorant and dispersed nanoparticulate colloidal silica at a concentration of from 0.1 to about 10 wt %, and the black ink comprises a black colorant and dispersed nanoparticulate colloidal silica at a concentration of from 0 wt. % to at most ½ of the wt. % of the dispersed nanoparticulate colloidal silica in the yellow ink.Type: GrantFiled: March 31, 2011Date of Patent: March 19, 2013Assignee: Eastman Kodak CompanyInventors: Douglas Eugene Bugner, Barbara Boland Lussier

Patent number: 6264321Abstract: A recording process is provided for producing recorded images having enhanced durability. The process includes applying droplets of ink by means of an ink-jet printer or a pen plotter in an image-wise fashion onto the surface of an ink-receiving layer supported on a transparent, plastic film support to record an image thereon, contacting the surface of the ink-receiving layer containing the recorded image against an opaque or transparent substrate to form a composite of the supported ink-receiving layer and the opaque or transparent substrate so that the ink-receiving layer containing the recorded image is positioned between the substrate and the transparent, plastic film support and then applying sufficient heat and pressure to the composite thus formed to adhere or laminate the supported ink-receiving layer to the substrate so that the recorded image is protected by the transparent, plastic film against abrasion, smearing, fading and water damage.Type: GrantFiled: August 14, 1997Date of Patent: July 24, 2001Assignee: Eastman Kodak CompanyInventors: Douglas Eugene Bugner, Alfred John Amell, Douglas Edward Garman
