Abstract

A method and a device for imaging a printing form (48) via at least two imaging modules (40,418) which each have at least one light source are disclosed for avoiding the banding effect that an imaging in a transition region (416). The two imaging modules (40,418) are provided in such a manner that a number of at least partially not-simply connected printing dots are produced in the transition region (416) by the first imaging module (40) and the complementary, not-simply connected printing dots are produced in the transition region (416) by the second imaging module (418).
