Abstract
A substrate has a coding pattern printed on a surface thereof. The coding pattern encodes a plurality of Reed-Solomon symbols. Any one symbol has a value represented by m macrodots distributed amongst p possible positions within the symbol. The positions of the m macrodots amongst the p possible positions determines the value of the Reed-Solomon symbol. The macrodots of a first symbol that is adjacent to a second symbol are distributed such that the macrodots of the first symbol are not adjacent to the macrodots of the second symbol.
