    Abstract: Embodiments of the invention relate to ink compositions suitable for applications in the printing industry, for example continuous inkjet printing, including ultra-high speed continuous inkjet printing. The ink compositions use volatile organic solvents, a colorant, and one or more binder resins including a resin that is a phenolic resole resin, wherein the ink composition is free of methanol, halogens, halogenated compounds and bisphenol-A. A phenolic resole resin of the ink composition preferably contains less than 0.1% by weight of free formaldehyde. The one or more binder resins including the phenolic resole resin may be present in an amount that is from about 5% to about 30% by weight of the ink composition.

    Abstract: A printer comprising a printhead configured to selectively cause a mark to be created on a substrate, a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead, a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor, and a controller arranged to generate control signals for the stepper motor. 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 printer comprising a printhead configured to selectively cause a mark to be created on a substrate provided adjacent to the printer, the printhead having a first configuration in which the printhead is spaced apart from the printing surface and a second configuration in which the printhead is configured to press the substrate against a printing surface during a printing operation. The printer further comprises a printhead drive assembly configured to cause movement of the printhead towards and away from the printing surface between the first and second configurations, the printhead drive assembly comprising a permanent magnet and an electromagnet. When the electromagnet is in a first condition, an attractive magnetic force is generated between the permanent magnet and the electromagnet, and when the electromagnet is in a second condition, a repulsive magnetic force is generated between the permanent magnet and the electromagnet, each of said attractive and repulsive magnetic forces being configured to one of urge the printhead away from and towards the printing surface. The printhead drive assembly is configured such that, when the printhead is in each of the first and second configurations, it is retained in that configuration by the printhead drive assembly when the electromagnet is in the first condition, the printhead being retained in one of the first and second configurations by said attractive magnetic force generated between the permanent magnet and the electromagnet.

    Abstract: A labelling machine comprises a supply spool support for supporting a supply spool comprising label stock; a take-up spool support adapted to take up a portion of the label stock; a motive device configured to propel the label stock along a web path from the supply spool support towards the take up spool support; a first arrangement configured to produce a first signal indicative of a speed at which label stock is removed from the supply spool by the motive device; a controller configured to receive the first signal and output a brake assembly control signal based upon the first signal; and a brake assembly configured to apply a braking force to the supply spool support based upon the brake assembly control signal, the braking force resisting rotation of the supply spool support. The controller is configured to output the brake assembly control signal based upon a target supply spool speed.

    Abstract: A method for measuring the volume of liquid, such as ink or solvent, remaining in a container, such as a replacement cartridge for a continuous ink jet printer, uses a reservoir enclosing an internal space having a variable volume for storage. The reservoir is adapted to provide a reduction in the pressure of the internal space, the reduction substantially monotonically increasing in magnitude as liquid is drawn into the printer, such that the volume of liquid remaining may be calculated from knowledge of the minimum withdrawal pressure required to draw further liquid from the reservoir into the printer. Containers for use with the method have a liquid dispensing port adapted to allow liquid to be dispensed when a withdrawal pressure at the exterior of the port is less than the pressure of the internal space and adapted to prevent the ingress of air into the internal space of the reservoir as liquid is dispensed.

    Abstract: A capping device for an ink jet print head, includes a base, the base configured to receive an ink jet print head comprising nozzles for ejecting ink in a print direction, and a cap assembly attached to the base and configured for movement between a closed position when the print head is not printing and an open position to allow for the ejection of ink from the nozzles when the print head is printing. The cap assembly includes a cover support configured for generally planar movement with respect to the base in a direction perpendicular to the print direction and a cover attached to the cover support in a generally planar relationship thereto. The cover is adapted to provide additional movement with respect to the cover support in a direction different from the planar movement in the direction perpendicular to the print direction.

    Abstract: A viscometer includes a housing and a bob disposed in the housing such that a gap is provided between the bob and the housing. The bob includes a magnet. A linear support supports the bob such that the bob is free to rotate with respect the housing. A flow inlet in the housing provides fluid flow into the housing. A flow outlet provides fluid flow out of the housing. At least one coil is disposed adjacent the housing for providing a magnetic field to induce oscillating rotational movement in the bob and to measure the movement of the bob. The viscometer is configured to measure a viscosity of a fluid by inducing movement in the bob and measuring a dampening effect of the fluid.
