Abstract
A two-dimensional graphic code includes a plurality of characters printed on a medium, arranged so that they are contiguous to one another and organized in a primary reading direction and a secondary reading direction. Each character is defined by a respective matrix of dots having selectively one between a high brightness level and a low brightness level and includes a respective usable submatrix and a respective separation region. The usable submatrix includes at least two contiguous dots both having the low brightness level, and the separation region is configured so as to outline the respective usable submatrix all along two adjacent sides.
Claims8
A two-dimensional graphic code comprising a code body, decoding indicia, and a plurality of characters printed on a medium in a contiguous arrangement and organized according to a primary reading direction and a secondary reading direction;
- characterized in that each character comprises a respective usable submatrix and a respective separation region, the usable submatrix comprising at least two contiguous dots both having the low brightness level and the separation region being configured so as to outline the respective usable submatrix along two adjacent sides;
- and
- wherein the decoding indicia includes a header field repeated on opposing sides of the code body, the header field containing information relating to code body dimensions, code body maximum capacity, and code body density.
