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.
