Abstract
A screening system comprises at least one screen of which the phase is tone or image level dependent. This tone dependent phase shift influences the rosette structure and can be used to improve the neutral balance and color fidelity in multi-color reproduction and to minimize the visibility of such rosette structures in highlight and shadow areas.
