Abstract
A relief print master is created by a printhead that jets droplets of a polymerisable 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 different constituting printheads. The distance between these spiral paths is not even in a prior art system. By rotating the printhead under a specific angle, the distance between these spiral paths becomes even. The invention can also be used for the creation of other types of print plates, such as for example offset print plates.
