    Abstract: Disclosed are opaque ink jet ink compositions and a method of printing that produce messages having a good contrast on darkly colored substrates, particularly darkly colored glass substrates, and that do not smear or degrade when exposed to moisture and/or hot and cold humid conditions, or when exposed to ice water or water under sterilizing conditions. The ink jet ink compositions comprise one or more organic solvents, one or more white pigments, one or more hydrophobic conductive agents, and one or more binder resins. In an embodiment of the ink jet ink composition, at least one binder resin comprises an acrylic or styrene acrylic resin. In another embodiment, the ink jet ink composition is free of polyamines. The ink jet ink composition may also include a glass adhesion promoter.

    Abstract: A printer comprising a printhead configured to selectively cause a mark to be created on a substrate. The printer comprises a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead relative to a printing surface against which printing is carried out, and to control the pressure exerted by the printhead on the printing surface. The printer further comprises a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor. The printer further comprises a controller arranged to generate control signals for the stepper motor so as to cause a predetermined torque to be generated by the stepper motor; said control signals being at least partially based upon an output of said sensor.

    Abstract: There is provided a thermal transfer printer 1, which comprises: a printhead 5; a tape drive configured to cause an inked ribbon 7 to be advanced past the printhead 5 so as to allow ink to be removed from the inked ribbon by the printhead and transferred to a substrate during a printing operation; and a printhead carriage 11 on which the printhead 5 is mounted, wherein the printhead carriage 11 is supported by a rail 34 coupled to a body 2 of the printer, and the rail 34 extends along a direction parallel to a direction of travel of the inked ribbon 7; wherein the printhead carriage 11 further comprises a first structure 40 which is arranged to engage with a second structure 50 coupled to the body 2 of the printer, and wherein the first and second structures 40, 50 are configured such that the printhead carriage 11 is rotatable around the rail 34 but a rotation of the printhead carriage around the rail remains within a predetermined range.

Said control signals being at least partially based upon an output of said sensor and at least partially based upon a target position. Said control signals for the stepper motor are arranged to cause a magnetic field to be generated by windings of the stepper motor. A field angle being defined between an angular position of the output shaft of the stepper motor, and an orientation of the generated magnetic field. Said control signals comprise a first control signal configured to cause said field angle to have a predetermined value, and a second control signal configured to cause said magnetic field to have a predetermined magnitude, and said controller is configured to vary said first and second control signals based upon said target position and said output of said sensor.

    Abstract: A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

    Abstract: A binary array ink jet printhead assembly includes a cavity for containing ink, nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form droplets, the nozzle orifices extending along a length of the cavity, and an electrode assembly. The electrode assembly includes a front face configured to be disposed generally parallel to a plurality of droplet paths of droplets from the nozzle orifices. A plurality of charge electrodes are disposed on the front face, each charge electrode corresponding to a droplet path and disposed parallel to the droplet path. Circuitry is disposed on the electrode assembly, wherein each electrode is electrically connected to the circuitry. The circuitry is further in electrical connection to a connector for connecting the electrode assembly to a controller for the printhead.
