Patent number: 8177332Abstract: An apparatus prints and/or fixes ink on a substrate, such as in ink-jet printing with UV-curable inks. A conformable member is positioned to contact an ink-bearing side of the substrate at a nip. The conformable member substantially comprises a silicone-based elastomer having a conformability from about 20 shore A to about 10 shore A. A radiation source directs radiation to the ink-bearing side of the substrate at the nip, the radiation suitable for curing the ink on the substrate. The apparatus is particularly useful for printing onto corrugated cardboard or otherwise non-planar surfaces, since the resulting ink image is impressed uniformly onto the substrate by the conformable member without voids in the ink layer in the recesses of the non-planar surface.Type: GrantFiled: January 13, 2009Date of Patent: May 15, 2012Assignee: Xerox CorporationInventors: Michael D Thompson, Steven E Ready, Gregory J Kovacs

Publication number: 20110261127Abstract: Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.Type: ApplicationFiled: April 21, 2010Publication date: October 27, 2011Applicants: Palo Alto Research Center Incorporated, Xerox CorporationInventors: Gregory J.

Patent number: 7879390Abstract: Black matrix (BM) material is deposited on glass and patterned to form walls that define an array of wells. Various surface treatments and masking schemes are utilized to achieve surface energy control of the BM glass. The surface treatments include one or more of chemically treating the BM walls by depositing hydrophobic self-assembled monolayers on the uppermost wall surfaces, and plasma treatments to control the surface energy of the various BM glass surfaces. Masking processes include backside exposure and development of photoresist, and maskless, self-aligned photo-patterning of the monolayers. Color filter ink is then injected into each well from an ink jet print head. The high surface energy of the lower and side wall surfaces facilitates wetting of the ink, and the low surface energy of the monolayers prevents intermixing of ink between adjacent wells. The ink then dries to form a color filter in each well.Type: GrantFiled: May 30, 2007Date of Patent: February 1, 2011Assignee: Palo Alto Research Center IncorporatedInventors: Alberto Salleo, Steven E. Ready
