Abstract: A method of operating a thermal transfer printer, the thermal transfer printer comprising first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead. The printhead is moveable towards and away from a printing surface, and, during printing, is configured to selectively transfer ink from the ribbon to a substrate as the substrate and printhead are moved relative to one another at a print speed. The method comprising causing relative movement between the ribbon and the printhead at a ribbon speed. A relative speed of movement between the ribbon and the substrate during printing is controlled based upon a force exerted upon the ribbon by the printhead during a printing operation, and/or a parameter indicative of an area of contact between a portion of the printhead and a portion of the printing surface.

Abstract: A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents comprise a solvent selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof. The one or more volatile organic solvents are present in an amount at least 60% by weight of the ink composition. The ink composition includes one or more binder resins present in an amount from 1% to 10% by weight of the ink composition, and one or more dyes. If water is present, it is present in amount less than 5% by weight of the ink composition. The ink composition includes less than 2% by weight of any humectant and/or wetting agent with a relative evaporation rate less than 0.3. The ink composition is suitable for use in a thermal ink jet printer.

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: The present invention is a thermal inkjet ink that provides good reliability at a wide range of industrial print conditions from both low temperature to high temperature environments across a broad range of humidities. It is particularly advantageous in low-temperature applications, for example, printing at temperatures down to 5° C. or lower continuously for 8 hours without developing print defects which can lead to unreadable codes; and, in the meantime also maintains other critical functional aspects including contrast, wetting, decap time, dry time, adhesion, ink cartridge stability, etc. The inks contain one or more binder resins that exhibit a hydroxyl number or acid number of at least 100 mg KOH/g; one or more terpene phenolic resins; one or more volatile organic solvents; and one or more dyes, and optionally further components.

Abstract: 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.
