Abstract
A substrate is printed with front side and back side markings. The front side when viewed with reflected light includes a first marking printed with a first gradient of a first color with increasing intensity from a first edge of the substrate to a second edge of the substrate. The back side when viewed with reflected light includes a second marking printed with a second gradient of the first color with decreasing intensity from the first edge of the substrate to the second edge of the substrate. The first gradient and the second gradient are selected for a combination of the first marking and the second marking, when viewed from the front side with transmitted light, to be seen with a same intensity of the first color at the first edge and the second edge.
