The figu re bel ow is e xt ra c ted f rom ISO/IEC 16022 (for the full table see Table 1‑1 ). A cco rdingl y, this se ction can approximate the si ze of a gi ven GS1 DataMatrix based on this pa rame te r.

The re fo re, the si ze of the resulting symbol va ries a cco rding to the amou nt of d ata en code d. GS1 DataMatrix is capable of en coding va riable length d ata. However the rectangular form with its limited height is better suited to some high speed printing techniques, and to unusual printing spaces.

T he squa re fo rm is the most commonly used and enables the en coding of the la rgest amou nt of d ata a cco rding to ISO / IEC 16022 In fo rm ation technology – Au tom atic Ide ntific ation and d ata captu re techniques – Data Matrix barcode symbology specific ation. It is possible to en code the same d ata in t wo fo rms of GS1 D ata M at rix:įigure 1 ‑ 2 A squa re fo rm versus a re ctangle fo rm When impleme nting GS1 DataMatrix, a choi ce of symbol fo rm must be made (based upon configu ration suppo r t, a vailable spa ce on the p rodu ct typ e, amou nt of d ata to en cod e, the p ri nting p ro ces s, e t c.). ġ.2.1 Sha pe and p resentation of the sym bol.O bviousl y, this co rner will be da rk if the GS1 D ata M at rix symbol is p ri nted in neg ati ve (i n verse refle ctan ce p ri nting). The re fo re it al w a ys has a lig ht “squa r e” in the upper rig ht hand rig ht co rner (ci rcled in the figu re ab o ve). GS1 DataMatrix always has an even number of r ows and columns. It has a consta nt width equal to the X -dimension of the symbol on each of the four side s.Įach D ata M at rix symbol is made up of number of r ows and column s. This is a lig ht a rea a round the symbol which must not co ntain a ny graphic eleme nt which m ay disrupt reading the barcode. Just like linear (1 D) barcodes GS1 DataMatrix has a mand ato ry Quiet Zon e. This is a t ransl ation i nto the bina ry GS1 DataMatrix symbology cha ra c ters (nume ric or alphanume ric).įigure 1 ‑ 1 Finder P at te rn and the d ata The d ata is then en coded in a m at rix within the Finder p at te rn. This defines the basic stru ctu re of the symbol and can also help de te rmine its si ze and dis to rtion. The other t wo sides of the finder p at te rn a re al te rn ating lig ht and da rk eleme nt s, kn own as the “ Clock T rac k”. It is p rima rily used to de te rmine the si z e, o rie nt ation and dis to rtion of the symbo l. The solid da rk is called the “L finder p at ter n”.
It has a fun ction similar to the Auxilia ry P at te rns ( Sta r t, Stop and Ce nt re p at te rns) in an EAN/UPC barcode and all ows the scanner to ide ntify the symbol as a GS1 D ata M at rix. The finder p at tern defines the shape (squa re or re ctangle), the si z e, X -dimension and the number of r ows and columns in the symbo l.
GS1 D ata M at rix is composed of t wo sepa rate pa rts (see figu re bel ow): the finder p at tern, which is used by the scanner to loc ate the symbo l, and the en coded d ata itsel f. The GS1 DataMatrix is formed by adding FNC1 codeword in the first position of D ata M at rix ECC 200 version. GS1 D ata M at rix is the ISO/IEC re co gnised and standa rdised impleme nt ation of the use of D ata M at rix. A d ata ca rrier is a graphical rep rese nt ation of d ata in a machine readable fo rm, used to enable au tom atic reading of the Eleme nt St ring s. The si ze of these dots is kn own as the X -dimension.īe fo re reading this docume nt one should kn ow the dif fe ren ce be t ween d ata ca rrier and d ata stru ctu re. The d ata is en coded using a se ries of da rk or lig ht dots based upon a p r e -de te rmined si z e. The finder p at tern is pa rtly used to specify the o rie nt ation and stru ctu re of the symbo l. This rep rese nt ation is an o rde red g rid of da rk and lig ht dots bo rde red by a finder p at te rn. GS1 D ata M at rix is a m at rix (2D or t w o -dimensional) barcode which m ay be p ri nted as a squa re or re ctangular symbol made up of individual dots or squa re s.
