摘要： A continuous inkjet system and method has a stimulation device producing a modulation in a liquid jet having a wavelength λ and causing a first liquid droplet to break off from the liquid jet and travel along a path and causing a second liquid droplet to break off from the liquid jet and travel along the path. The first liquid droplet has a first break off length and the second liquid droplet has a second break off length longer than the first break off length. The first break off length and the second break off length have a difference of at least one wavelength λ in response to stimulation pulses. A charge electrode produces a charge differential between the first liquid droplet and the second liquid droplet, and a deflection mechanism causes trajectories of the first liquid droplet and the second liquid droplet to diverge so that a trajectory of one droplet of the first and second liquid droplets causes the one droplet to be directed for collection and prevented from depositing on the surface and a trajectory of the other droplet of the first and second liquid droplets causes the other droplet to be directed for depositing on the surface. A stimulation controller identifies a transition in droplet creation between a stimulation cycle that is to produce a droplet having a second break off length and a stimulation cycle that is to produce a droplet having a first break off length and introduces a skip cycle between the stimulation cycle that is to produce the droplet having a second break off length and the stimulation cycle that is to produce the droplet having the first break off length.

摘要： A continuous inkjet system includes a plurality of nozzles producing a respective liquid jet through each nozzle. A stimulation device at each nozzle is responsive to different types of stimulation signals to produce a modulation in the respective liquid jet to selectively control droplet break off relative to phases of the cycle of a varying voltage source that is connected to a charge electrode. The break off phase of a droplet relative to the voltage phase of the voltage source will determine whether the droplet is charged or not charged. Droplets that become charged may be deflected from their paths and a deflection mechanism including the charge electrode determines which droplets are allowed to reach a surface for say printing and which droplets are collected and not deposited upon the surface.

摘要： A system is described for tracking a position of a receiver medium as it travels along a media path. A laser provides heat to the receiver medium in a localized area sufficient to permanently alter a physical property of the receiver medium thereby forming a reference mark. A sensor at a downstream position along the media path is adapted to sense the reference mark providing a sensed signal. The sensed signal is analyzed to determine a position of the receiver medium as the receiver medium passes through the second position along the media path by detecting a position of the reference mark.

摘要： A printing system for printing on a print medium is disclosed. A first linehead is disposed opposite a first side of the print medium. The first linehead defines print zones where a liquid is deposited onto the first side of the print medium. A plurality of transport rollers are disposed adjacent to the second side of the print medium. At least one transport roller is aligned with one of the one or more print zones of the first linehead. A vacuum manifold is disposed opposite the second side of the print medium. The vacuum manifold is aligned with the aligned transport roller and outputs a vacuum force that operates on the second side of the print medium to deflect the print medium causing an increase in the wrap angle of the print medium around the aligned transport roller.

摘要： A method for color density correction in a printing system that includes a linehead, with one or more printheads, that jets ink onto a moving print media and an integrated imaging system that captures images of content printed on the moving print media is provided. One or more pixel data values and a measured density value trace for a printed test block are produced by scanning the test block and averaging pixel data in a print media transport direction. A color and a density of the ink in the printed test block are determined using the pixel data values. The measured density value trace is compared with a respective reference density value. It is determined whether there is a difference between the measured density value trace and a reference density value is determined. If there is a difference, ink laydown for the printhead is adjusted based on the difference.
