Abstract
A system and method for developing a bar code representing the encoding of a set of data, in which the bar code includes pixels having one black level, one white level and at least one gray level, generates a multi-level data representation of the set of data, the number of levels corresponding to the sum of the black level, the white level and the number of gray levels. A pixel color is determined for each component of the multi-level data representation, a pixel color for at least one of the components being one of the at least one gray levels. The determined pixel color is then printed for each component to form the bar code.
