A bidimensional graphic matrix code 1 has a plurality of words orientated along a first direction (D1), each word (2) formed from characters (3) arranged along a line which is parallel to the first direction (D1). Each character is formed from a first dot matrix, each dot (5) having a determined level of luminosity. Delimiting elements delimit each word, the delimiting elements orientated along a second direction (D2) which is perpendicular to the first direction (D1). Each delimiting element is formed by a line of dots arranged parallel to the second direction (D2). Each delimiting element is identifiable as groups arranged in a line, each group (8) comprising dots (5) having predetermined levels of luminosity, the delimiting elements interposed between adjacent words, such that identification of a delimiting element (6) enables identification of an initial or a final part of a word (2) adjacent to the delimiting element. |

1. A bidimensional graphic matrix code (1), comprising:
a plurality of words (2) orientated along a first direction (D1), each word (2) comprising in turn a plurality of characters (3) arranged one after another along a line which is parallel to the first direction (D1), each character (3) comprising a first dot matrix having lines of dots (5) that develop along the first direction (D1) and columns of dots (5) that develop along the second direction (D2), each dot (5) having a determined level of luminosity; a plurality of delimiting elements (6) for delimiting each word (2), which delimiting elements (6) are orientated along a second direction (D2) which is perpendicular to the first direction (D1); each delimiting element (6) comprising at least a line of dots (5) which is parallel to the second direction (D2); each delimiting element (6) being identifiable in that a plurality of groups (8) are recognizable therein, arranged in a line one after another, each group (8) comprising dots (5) having predetermined levels of luminosity; each delimiting element (6) is interposed between adjacent words (2) arranged along the first direction (D1), such that identification of a delimiting element (6) enables identification of an initial or a final part of each word (2) adjacent to the delimiting element (6); each group (8) forming each delimiting element (6) is adjacent to a character (3) of a respective word (2) in such a way as to be in contact with the character (3), such that identification of a group (8) of a delimiting element (6) enables identification of a position of a word (2) adjacent to the group (8) along the second direction (D2); each group (8) is formed by a second dot matrix having one or more columns of dots (5) that develop along the second direction (D2), wherein the number of dots (5) of the one or more columns of each group (8) is equal to the number of dots (5) of the columns of each character (3), and wherein each group (8) is aligned along the second direction (D2) with a word (2) adjacent thereto; wherein the dots (5) of a same group (8) of each delimiting element (6) exhibit, within the group, a same level of luminosity and wherein the dots (5) of groups (8) adjacent to one another exhibit a different level of luminosity in that a group (8) of a delimiting element (6) adjacent to a first character (3) of a respective word (2) has a different level of luminosity with respect to a group (8) of a delimiting element (6) adjacent to a last character (3) of the same word (2); and each character is formed by matrices of a 2×2 type in which a single low-luminosity dot is included, in which different positions of the low-luminosity dot encode different characters. |
