Patent number: 8699091Abstract: A system for previewing and imaging a document includes an imaging unit having an imaging surface configured to carry the document thereon. The imaging unit also includes an image sensing member configured to capture an image corresponding to the document and an image processing member communicably coupled to the image sensing member to receive the captured image. The image processing member is further configured to convert the captured image to a digital data format. The system further includes a display unit communicably coupled to the image processing member. The display unit includes a user interface configured to exhibit a placement-guiding display object over converted captured image.Type: GrantFiled: December 29, 2010Date of Patent: April 15, 2014Assignee: Lexmark International, Inc.Inventors: Robert Rumford, Rebecca Silveston-Keith, Mark Edwards

Publication number: 20080057231Abstract: The present invention relates to ink-receiving print media products capable of improving smear for pigmented inks. The products have at least one ink-receiving layer supported by a substrate. The ink-receiving layer includes a binder blend and a pigment, for example, polyvinyl alcohol, styrene-acrylate copolymer, and silica. The print media product has excellent smear resistance when pigment-based ink is printed on the ink receiving layer of the substrate.Type: ApplicationFiled: June 27, 2006Publication date: March 6, 2008Inventors: Jun Li, Yaqiang Frank Ming, Rebecca Silveston-Keith

Publication number: 20080044633Abstract: The present invention relates to a method and materials that improve the printing properties of pigmented inks on glossy media, especially smear resistance, gloss, and differential gloss. The method is to apply a very uniform thin coating based on low molecular weight water-soluble polymers such as polyvinyl alcohol and acrylic resins and medium-high molecular weight polymer emulsion/dispersion on printed images. The polymers have good film formation and mechanical/physical properties. They also preferably have good jettability, either by thermal or piezo methods. The thin coating is preferably applied by jetting process through one of chambers of the ink cartridges, but can be applied by other processes such as Meyer rod, roll coater, etc.Type: ApplicationFiled: June 30, 2006Publication date: February 21, 2008Inventors: Yaqiang Frank Ming, Rebecca Silveston-Keith

Patent number: 7041424Abstract: Reactive toners are printed by electrophotographic and electrographic printers. One or more of the toners may include reactive components. An additional toner, which may be a colorless toner, comprises reactive components. The toners comprising one or more colorants are used to from an image on a substrate. The additional toner is used to cover the entire image, although the additional toner may be printed over, or under, the image, to cover the image as the image is printed on the substrate. The reactive components of the additional toner provide a base that covers at least the entire image to improve adhesion of the image layer with the final substrate, particularly where substrates having rough surfaces, such as textiles, are used as the final substrate.Type: GrantFiled: August 11, 2003Date of Patent: May 9, 2006Inventors: Ming Xu, Rebecca Silveston

Patent number: 6887640Abstract: A process for printing images by means of an electrographic or electrostatic device using a toner that is cured by multiple applications of energy. The toner has energy-activated reactive components such as radiation-curable sites and reactive functional groups. An image is formed on a substrate by the toner without materially activating the reactive components. The reactive components are subsequently activated by applying a first energy source to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate. A second energy source is applied simultaneously with, or subsequently to, the first energy source, to promote cohesive strength of the image by cross-linking within the toner particles that form the image. The resulting image is permanently bonded to the substrate, yielding substantially enhanced image durability and fastnesses.Type: GrantFiled: February 28, 2002Date of Patent: May 3, 2005Inventors: Sukun Zhang, Rebecca Silveston, Ming Xu

Patent number: 6849370Abstract: A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents.Type: GrantFiled: October 16, 2001Date of Patent: February 1, 2005Inventors: Barbara Wagner, Rebecca Silveston, Ming Xu
