Abstract:
1. A rolled product of contiguous separable sheets, comprising: at least a first and second contiguous separable sheet of product wound around an axis, forming a cylindrical roll, each sheet having an outer edge positioned parallel to the axis; and at least the first and second contiguous separable sheet of product having at least one indicium that bears a predetermined relationship when the first sheet is the outer most sheet of the rolled product, such that a discontinuity of the indicium is likely to be formed between the outer edge of each sheet having the indicium and the portion of the indicium which lies directly beneath the outer edge of each sheet having the indicium when the sheets are formed into a cylindrical roll, wherein at least the first and second sheet of contiguous separate sheets of product have a plurality of indicium, wherein the plurality of indicium are each a continuous undulating indicium, wherein the plurality of indicium are out-of-phase from each other, wherein each of the continuous undulating indicium are sinusoid-shaped having a predetermined wavelength, wherein the sheets are of length L and the wavelength of each of the sinusoid-shaped indicium are substantially equal to L.
