  • Publication number: 20070182797
    Abstract: A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has alternatively hydrophilic and hydrophobic areas, causing the ink to form droplets on the wire for printing them as discrete pixels onto the substrate.

  • Publication number: 20060142415
    Abstract: Disclosed herein is a method of making an inkjet ink, comprising milling a pigment in an organic solvent to form a millbase, wherein the millbase is substantially free of polymerizable components; and mixing a polymerizable composition with the millbase to form a polymerizable ink.

  • Publication number: 20050166783
    Abstract: The present invention relates to an imaged article comprising a substrate having a primed surface layer. The primed surface layer is comprised of a base polymer having a solubility parameter, molecular weight (Mw) and glass transition temperature within a specified range. The presence of the primer improves the overall image quality by improving at least one property including ink uptake, dot gain, color density and/or ink adhesion. Preferred primer compositions are soluble at least in part in the ink composition resulting in an increase in ink layer thickness that further improves the durability and/or day/night color balance. A variety of substrates may be primed including various sheeting for traffic control signage and commercial graphic films for advertising and promotional displays.

  • Publication number: 20050018026
    Abstract: Inkjet printing apparatus for use with radiation curable ink includes a sensor for sensing the amount of radiation emitted by a source of radiation. A controller is connected to the sensor and is operable to vary the amount of radiation emitted by the radiation source in accordance with a signal received from the sensor. A drive mechanism moves the source of radiation to a location laterally offset from the substrate where the sensor is positioned.

  • Patent number: 6730376
    Abstract: A photocurable thermally transferable composition containing a multifunctional monomer that is substantially non-liquid at room temperature and a thermoplastic binder is disclosed. The composition is suitable for use in thermal transfer ribbons. After thermal transfer, the compositions are photocured to provide a durable, weatherable image on a graphic article.

  • Patent number: 4982097
    Abstract: This invention is designed to serve as an interface between a liquid chromatograph and a conventional or tandem mass spectrometer (LC/MS, LC/MS/MS). It may also be used for liquid sampling without prior separation of analytes by a liquid chromatograph. This invention differs from prior art in that vaporization of the analytical sample (LC eluent) occurs through the action of condensing pressurized steam on the exterior of a low thermal mass metal capillary, while the aqueous LC eluent is flowing through the metal capillary. The steam is obtained by heating a small volume of water sealed within the device. LC eluent entering the capillary results in localized cooling and subsequent condensation of the pressurized steam on the outer surface of the capillary. The process of condensation deposits energy to the capillary equivalent to the latent heat of vaporization of water. This energy results in flash vaporization of the LC eluent within the capillary.
