  • Patent number: 9662879
    Abstract: A method for stabilizing a print quality in an inkjet printing system is described. The inkjet printing system can include a nozzle arrangement that may be activated with a number of control signals that can be used to fire ink droplets with corresponding different droplet sizes onto a recording medium. In the method for stabilizing a print quality in an inkjet printing system, a rastered image for an image template can be created. The rastered image can be printable by the inkjet printing system using a subset of the different droplet sizes. Further, the nozzle arrangement can be activated with a control signal for an unused droplet size of the different droplet sizes to induce the nozzle arrangement to generate a prefire pulse.

  • Patent number: 9302474
    Abstract: 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.
