摘要： A liquid ejection apparatus includes: a plurality of nozzles configured to eject liquid onto a conveyed object conveyed by a conveyance unit, based on input image data; and a control unit configured to control a number of droplets in first flushing for ejecting the liquid outside a region corresponding to the image data and a number of droplets in second flushing for ejecting the liquid inside the region corresponding to the image data in addition to ejection based on the image data. The control unit is configured to control the number of droplets in the first flushing and the number of droplets in the second flushing based on at least a length of the image data in a direction in which the conveyed object is conveyed.

摘要： A printing system, print control device, and print control method enable non-technical users without specific technical knowledge to appropriately set the flushing conditions of a printer. A host that sends commands to an inkjet printer that prints on a print medium provides a user interface for selecting an operating mode prioritizing the throughput of the printing operation, or a normal operating mode. When the operating mode prioritizing printer throughput is selected using the user interface, the host generates a command setting a condition for flushing the ink nozzles of the inkjet printer, and sends the generated command to the inkjet printer.

摘要： A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.

摘要： In an embodiment, a method of maintaining nozzles in a print-ready condition includes determining image content to be printed in an upcoming print swath, and for each ink color present within the image content, constructing an inked portion of an associated spit bar adjacent to the upcoming print swath to include the present ink color. For each ink color not present within the image content, an empty portion of an associated spit bar is constructed adjacent to the upcoming print swath.

摘要： An inkjet printing apparatus includes a transport speed detector for detecting transport speed of a printing medium, an inkjet head having a plurality of discharge portions for discharging ink droplets from the discharge portions for printing, and a flushing controller for carrying out discrete flushing from the discharge portions. For an acceleration area of the printing medium where the transport speed detector detects an increase in transport speed before printing, a first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing. For a constant speed area of the printing medium where the transport speed detector detects a substantially constant transport speed during printing, a second discharge rate lower than the first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing.

摘要： In a method to control vibration measures and refresh measures in a printing operation of an ink printing system with at least one printing apparatus, the printing apparatus having printing elements that fire ink droplets as print dots at a printing substrate depending on control data determined from print data associated with print images and firing pause information about firing pauses for the printing elements. Prefire data and refresh data derived from the firing pause information and from operating condition information of the printing apparatus are combined with the control data. The vibration measures and refresh measures are executed by the printing elements depending on the firing pause information, the prefire data, and the refresh data, no ink droplets being ejected during the vibration measures and ink droplets being ejected during the refresh measures.

摘要： A multi-color printer has an array of monochrome fixed inkjet printheads aligned in a media feed direction. The printer includes: a first printhead positioned furthest upstream relative to the media feed direction; a second printhead positioned furthest downstream relative to the media feed direction; and a third printhead positioned between the first and second printheads. Each printhead is supplied with a respective ink from a multi-color ink set, the first printhead being supplied with a lowest luminance ink of the ink set and the third printhead being supplied with a highest luminance ink of the ink set.
