<p>A relief print master is created by means of a printhead that jets droplets of a polymerisable liquid on a cylindrical sleeve. The droplets follow a spiral path (950,951) on the cylindrical sleeve. In a multiple printhead unit, there are different spiral paths associated with the constituting printheads in the multiple printhead unit. The distance between the spiral paths is not even. The invention provides a method and a system so that the distance between these spiral paths (950,951) becomes even by adjusting the distance (920,921) measured in the direction of the cylindrical support between marking elements of different rows of the multiple print head unit. The system can also be used for the creation of other types of print masters, such as offset print plates.</p> |
