Summary:A method for forming a pattern of metallic nanofeatures that generates by plasmonic resonance a desired image having a distribution of colours, which method includes providing a substrate having a layer of photosensitive material, exposing the layer to a high-resolution periodic pattern of dose distribution, determining at least one low-resolution pattern of dose distribution such that the sum ofthe at least one low-resolution pattern of dose distribution and the high-resolution periodic pattern of dose distribution is suitable for forming the pattern of metallic nanofeatures, wherein the lateral dimensions of said metallic nanofeatures have a spatial variation across the pattern that corresponds to the distribution of colours in the desired image, exposing the layer of photosensitive material to said at least one low-resolution pattern of dose distribution, developing the layer of photosensitive material to produce a pattern of nanostructures in the developed photosensitive material,processing the pattern of
