A method of printing a substrate with ink drops, image-wise, utilizing an inkjet printing device containing at least one print head provided with at least one row of nozzles, the substrate forming a regular field of pixel rows and pixel columns, the resolution of the pixel columns being equal to the resolution of the row of nozzles, wherein a first printing stage is initiated in which a strip of pixel rows is provided with ink drops, whereafter the print head is displaced in a direction substantially parallel to the pixel columns, and a second printing stage is initiated in which the strip is provided with supplementary ink drops, wherein the print head is displaced over a distance such that the same is substantially equal to the width of one pixel row.

Method of printing a substrate and a printing device suitable for use of the method

A printing device having multiple print heads is disclosed, which obviates the need to dynamically control temperature differences between distinct print heads. The printing device is provided with a heat exchange device for bringing the temperature of each print head to a predetermined temperature value, and with an adjustment device for adjusting the temperature of one or more print heads from the predetermined temperature values to a static target temperature value. The target temperature values are determined in relation to an output parameter of the printing system such that a minimal adjustment is required. Also disclosed a method for controlling device.
