Patent number: 8354213Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a cyan toner with a lower colorant loading in addition to a first cyan toner. In embodiments, the cyan pigmented particles may be cyan emulsion aggregation toners. In accordance with the present disclosure, a pair of cyan toners are matched in color, wherein the color of a first cyan toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second cyan toner, which is lighter than the first cyan toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light cyan toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 500 and 600 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers.Type: GrantFiled: January 19, 2010Date of Patent: January 15, 2013Assignee: Xerox CorporationInventors: Daryl W. Vanbesien, Karen Ann Moffat, Yi Xin Gong, Edul N. Dalal, Jing Wang, Richard P. N. Veregin, Jordan H. Wosnick, Cuong Vong, Valerie M. Farrugia

Patent number: 8288067Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV additive that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV additive and ionic crosslinker, with optional chelating agent, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.Type: GrantFiled: March 26, 2009Date of Patent: October 16, 2012Assignee: Xerox CorporationInventors: Yi Xin Gong, Shigang Qiu, Daryl W. Vanbesien, Gabriel Iftime, Edward Graham Zwartz, Karen Ann Moffat, Richard P. N. Veregin

Patent number: 8211600Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable.Type: GrantFiled: August 21, 2011Date of Patent: July 3, 2012Assignee: Xerox CorporationInventors: Daryl Vanbesien, Karen Moffat, Yi Xin Gong, Edul Dalal, Jing Wang, Richard Veregin, Jordan Wosnick, Cuong Vong, Valerie Farrugia
