Abstract: The present invention is drawn to photo-curable ink-jet ink compositions, systems, and methods. One exemplary ink-jet ink composition includes a liquid vehicle, a milled pigment, a photo initiator and a halogenated polyolefin. In this embodiment, the addition of the halogenated polyolefin improves adhesion to a non-porous substrate or a low surface tension substrate such as polypropylene.

Abstract: A method of selecting a wireless network for a plurality of mobile client terminals. The method comprises monitoring at least one network selection parameter of each of a plurality of wireless networks in a plurality of different geographical areas, identifying a group of the plurality of wireless networks which are available for providing a network service to a first of a plurality of mobile client terminals in one of the plurality of different geographical areas, selecting at least one member of the group according to respective the at least one network selection parameter, and sending a network message instructing the first mobile client terminal to establish automatically a connection via the at least one member.

Abstract: The present invention is drawn to photo-curable ink-jet ink compositions, systems, and methods. One exemplary ink-jet ink composition includes a liquid vehicle, a milled pigment which has been milled in a milling solvent having minimal to no gas solvency for the milled pigment, and a photo initiator. In this embodiment, the composition can be ink-jettable at frequencies of at least 29 KHz without requiring degassing during printing.

Abstract: The present invention is drawn to ink compositions and methods for ink-jet recording. The ink compositions can include a non-aqueous HAPS-free solvent system; a binder system, including at least one of i) an acrylic resin, or ii) a first vinyl chloride-vinyl acetate resin, which is at least substantially soluble in the solvent system; and a pigment milled in the presence of a second vinyl chloride-vinyl acetate resin. Further, at least one solvent of the solvent system can serve as a dispersing and diluent solvent for the pigment.
