Methods, systems and computer readable media for imposing monotonic consistency among results of multiple platforms measuring the same specific property for the sameequivalent series of samples, to provide viable comparisons of sensitivity and precision among the platforms as well as provide useful conversion formulas among the platforms to ensure equivalent quantitation. The generated image is \u201cbuilt up\u201d on the carrier sheet or substrate to form a sign, thereby eliminating the need for the weeding process. In one embodiment, the slot is sized andor magnetized to allow a head of a nail to be supported therein so that the nail is cantilevered substantially perpendicular relative to the striking surface.
