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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： There is provided a charge electrode for charging ink droplets for continuous ink jet printing. The charge electrode has a generally cylindrical main body defining a generally cylindrical passage for the ink droplets, said passage extending along a travel axis that represents, in use, the position of an ink jet in ingress to the electrode and a direction of travel of the ink droplets once these have detached from the ink jet. The charge electrode comprises two distinct axially disposed regions: a first region for charging the droplets as required; and, a second region for screening the charged droplets from any electric fields which could undesirably affect the trajectory of the ink jet and/or the droplets. The second region may fully surround at least a portion of the travel axis. The invention therefore provides improved screening for the ink jet and/or the droplets. This may in turn enable better control of the charge applied to the charged droplets, and/or of their travel trajectory.

摘要： A spool support, for supporting a windable material, comprises a main body, an actuator and a clamp portion. The actuator is movable relative to the main body between a first position and a second position. The clamp portion is pivotably connected to the main body. The actuator actuates the clamp portion such that the clamp portion pivots relative to the main body between a retracted position when the actuator is in the first position and a deployed position when the actuator is in the second position.
