Abstract: A method for controlling a temperature of a jetting device, the jetting device being configured to jet droplets of a fluid at a high temperature, the fluid comprising an electrically conductive fluid, wherein at least a part of the fluid is positioned in a magnetic field, includes heating the jetting device to an operating temperature, being defined as the temperature suitable for jetting droplets, using a heat jetting droplets by providing an electrical actuation current in the part of the fluid positioned in the magnetic field, thereby generating a force in the conductive fluid; determining upcoming jetting conditions, the upcoming jetting conditions being defined as the jetting conditions corresponding to droplets to be jetted at a time (t1) which is later than the present time (t0); determining settings for the heat based on the determined upcoming jetting conditions; controlling the heating of the jetting device using the heat in accordance with the determined settings.

Abstract: A method includes deriving from print data a first intended position of a first dot to be printed, determining a first printing element from a plurality of printing elements suitable for printing the first dot at the first intended position, printing the first dot with the first printing element at a first location on the substrate, deriving from the print data a second intended position of a second dot to be printed, retrieving a tolerated deviation of a distance between the first intended position and the second intended position, determining a second printing element from the plurality of printing elements suitable for printing the second dot based on the tolerated deviation, and printing the second dot with the second printing element at a second location on the substrate.

Abstract: In a jetting device for ejecting droplets of a relatively hot fluid, a fluid chamber body is made of a heat resistant material and an inner surface of the fluid chamber body, the inner surface defining a fluid chamber of the jetting device, is wettable by the fluid. This configuration provides that no additional force needs to be applied for forcing the fluid into an orifice, i.e. a narrow tube leading towards a nozzle.
