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.

摘要： A printing system includes one or more lineheads disposed opposite a first side of a print media and at least one vacuum assembly having a vacuum manifold disposed opposite a second side of the print media. The linehead or lineheads has one or more print zones where a liquid or ink is deposited onto the first side of the print media. The vacuum manifold is aligned with a non-print zone of each linehead and outputs a vacuum force proximate to the second side of the print media such that at least a portion of the second side of the print media is deflected away from the lineheads. The printing system can also include another component, such as a dryer, disposed over the print media and laterally adjacent to the linehead. Another vacuum manifold can be disposed adjacent to the second side print media between the linehead and the component.

摘要： A printing system includes a linehead that jets ink onto a moving print media to print a test block and an integrated imaging system positioned downstream of the linehead with respect to a media transport direction. The integrated imaging system includes an opening in a housing for receiving light reflected from a moving print media. A folded optical assembly in the housing receives the reflected light and transmits the light a distance. One or more image sensors, having known color filter arrays, within the housing each receive the light and capture one or more images of the printed test block. An image processing device is connected to the integrated imaging system for receiving pixel data from the one or more image sensors and configured to determine a color of the ink and a density of the printed test block using the pixel data.

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 method of controlling a digital printing system that uses multiple metadata packets is provided. A controller including a metadata channel is provided. Information in a first metadata packet that is associated with an initial point of interest of a media is provided by a primary metadata packet creation unit. The first metadata packet is inserted into the metadata channel of the controller. A second metadata packet including new information associated with a new point of interest of the media is created using a secondary metadata creation unit. The second metadata packet with the new formation is inserted into the metadata channel of the controller based on the location of the new point of interest of the media.

摘要： A method of printing includes providing a printhead and providing a roller positioned downstream from the printhead. The printhead is used to selectively moisten at least a portion of the web of print media as the web of print media is guided through the printing system. The print media is caused to contact and wrap around a portion of the roller as the print media moves past the roller. The roller, having an axis of rotation, includes a pattern of recesses and ridges positioned along the axis of rotation of the roller. A second section of the roller is located between a first section of the roller and a third section of the roller as viewed along the axis of rotation. The roller includes a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller.

摘要： A liquid dispenser includes a liquid supply channel, a liquid dispensing channel including an outlet opening, and a liquid return channel. A liquid supply provides liquid under pressure from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A selectively actuatable diverter member imparts heat energy directly to a first portion of the liquid to divert a second portion of the liquid toward outlet opening of the liquid dispensing channel.
