A printed article comprising a substrate; a graphic image formed over the surface of the substrate; and a textured pattern printed over the graphic image with an embossed appearance and the capability of containing hidden images and unique security features. The textured pattern formed of a number of lines, formed in adjacent sections over the surface of the graphic image. The lines of each section are all substantially parallel to each other and oriented in a first direction, and the lines of a directly adjacent section are all substantially parallel to each other and oriented in a second direction different from the first direction, such that the plurality of parallel lines in each section reflect light in a direction different than that of each adjacent section. Each of directions of the lines is selected so as to minimize any errors introduced by equipment used to create the lines. |
