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 .
