Abstract: A printed article is disclosed having a light transmissive substrate having a reverse printed region on a surface thereof in the form of a plurality of very closely spaced printed lines or regions. The printed regions and spaces therebetween are subsequently flood coated with special effect ink such as optically variable ink wherein the ink particle size is on average greater than the gap between reverse printed regions. The image is viewed from the non-printed side of the substrate and very fine lines of the special effect flood coated special effect ink appear as very clear sharp lines having a fine resolution. This eliminates the typical jagged edges that would otherwise be seen if the inked region was not present. This effect is due to the first printed inked regions or lines forming a mask through which the flood coated ink is seen.
