  • Patent number: 7901063
    Abstract: An ink circulation system for use in an inkjet printing apparatus includes an inkjet printhead, an ink supply path for supplying an ink to the inkjet printhead and an ink return path for returning ink not used for printing from the inkjet printhead. The ink return path is coupled to the ink supply path for replenishing the ink supply path with the ink returned from the printhead. The coupling establishes an ink circulation circuit. The ink circulation circuit can be replenished with fresh ink from a main tank, as ink is withdrawn by the printhead for printing. In the circulation system an active through-flow ink degassing unit is provided to control the dissolved gas level of the ink in the ink circulation system.

  • Patent number: 7901024
    Abstract: A method of inkjet printing includes using a grayscale inkjet print head. The inkjet print head is driven driving to eject a number of successive ink droplets from the ink chamber in accordance with print tone data provided to the grayscale print head, the number of successive ink droplets forming a multiple-droplet drop creating a printed dot of appropriate tone on the receiving medium. The method includes the step of excluding print tone data corresponding with the ejection of a single-droplet drop from being provided to the grayscale print head. A preferred embodiment includes the removal of this print tone data from the data provided to the grayscale print head. A more preferred embodiment includes applying a multilevel halftoning technique for avoiding the use of print tone data corresponding with a single-droplet drop during the generation of the print tone data for inkjet printing the image with the grayscale print head.
