Title: Coding scheme for encoded sheet material

Abstract: An edge coding scheme for an encoded sheet material includes an offset marklocated at an offset distance from a reference mark on the edge of thesheet material and a plurality of equally spaced clock marks disposedalong the edge, such that the offset distance can be approximated by theproduct of the number of clock marks between the reference mark and theoffset mark times the distance between successive clock marks. Anotherembodiment of the edge coding scheme includes coincidence between a firstplurality of equally spaced apart clock marks and a second plurality ofequally spaced Vernier marks, wherein the second plurality is less thanthe first plurality.
