摘要：
A method for forming an optically variable device upon a substrate comprises the steps of: patterning a reflective layer on the substrate using an oil-ablation technique; removing oil residue from the first side of the substrate using a first glow discharge; and depositing thin-film layers so as to be supported by the substrate to form the optically variable device. Optionally, oil residue is removed from the second side of the substrate using a second glow discharge.
