Abstract
A digital printing machine includes a first cylinder for transporting sheets, a second cylinder for transferring the sheets directly to the first cylinder, a third cylinder for transferring the sheets directly to the second cylinder, and at least one inkjet print head directed towards the first cylinder for printing on the sheets disposed thereon. At least one first sensor measures the temperature of the first cylinder, a second sensor measures the temperature of the sheets while being transported by the second cylinder or by the third cylinder, and at least one temperature control device controls the temperature of the sheets prior to their transfer to the first cylinder. A control element adapts the temperature of the sheets to the temperature of the first cylinder. The first sensor, the second sensor and the temperature control device are connected to the control element.
