A relief print master is created with a printhead that jets droplets of a polymerizable liquid on a cylindrical sleeve. The droplets follow a spiral path 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. Preferred embodiments of the current invention provide a method and a system so that the distance between these spiral paths becomes even. The system can also be used for the creation of other types of print masters, such as offset print plates.
