A multi-readable information system includes a substrate material and one type of printed information that is readable by a first entity, such as information in machine readable bar code that is printed on an area of the substrate material. A different type of printed information occupies the same field area of the substrate material, such as information in human-readable symbology that is printed in at least a portion of the area occupied by the bar code. The bar code is printed in a first ink that can be read utilizing energy of a first wavelength and the human-readable symbols are printed in a second ink that can be read in a humanly visible wavelength. The humanly visible ink absorbs insufficient energy in the first wavelength to prevent reading of the bar code by a bar code-reading machine and the bar code does not interfere with the readability of the human-readable symbols.
