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 C5 ketone (pentanone) solvents (e.g., 2-pentanone, 3-pentanone, or 3-methyl-2-butanone) as a major solvent or the only solvent, and also include a binder resin and a colorant, but preferably contain substantially no acetone, methanol, or methyl ethyl ketone, or other solvents listed on the Japan ISHL class II organic solvents list. Preferred ink compositions can contain up to 30% ethanol, n-propanol, or other solvents not listed on the Japan ISHL class II organic solvents list, but preferably contain substantially no ethanol.

Abstract: A method of operating a continuous inkjet printer (1). The printer comprise a printhead. The printhead comprises a droplet generator (16) comprising a printing nozzle (17) for ejecting an ink jet for printing, at least one electrode (22, 23) for steering the inkjet, and a gutter (18) having an ink receiving orifice (24) for receiving parts of the ink jet which are not used for printing. The method comprises performing a cleaning operation. Said cleaning operation comprises: ejecting a solvent jet from the printing nozzle towards the gutter; and causing at least a portion of the solvent jet to contact at least a part of the gutter (18) surrounding the orifice (24) for cleaning said part of the gutter surrounding the orifice.

Abstract: A laser marking system comprises at least one controller to control an array of optical devices, between a laser source and a scan head. The array applies a selected pattern of portions of the received spatial profile of the laser beam to the substrate to achieve a second intensity different from the first intensity of laser beam at a rate of power deposition relative to a rate of thermal diffusion in the substrate for a predetermined time interval to thermally heat locations of the substrate with the selected pattern of the portions. The second intensity effectuates carbonization of materials of the substrate to create a mark without ablation.

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.
