Apparatus comprising: a support 3, 7 arranged to transport a moving substrate 2, a plasma generator 6 arranged to generate plasma 6 and an electrode arranged to bias ions within the plasma towards the moving substrate 2 to form an ion flux. The ion flux has an energy level between 3.6eV and 250eV. The ion flux is used to cure radiation curable material on the moving substrate 2. Apparatus for defining plasma having a plurality of spaced race track portions using magnetic arrays is also disclosed (Fig. 9). |
