Data Matrix

What is Data Matrix

Data matrix, primary called data code, is invented by International Data Matrix in 1989. Data Matrix is a square or rectangular matrix (2D) barcode symbology barcode, hoping to encode more information in a smaller barcode. Now, Data Matrix barcode is widely used in aerospace, air transport, and national security especially for labeling small electronic components, industrial ink-jet, dot-peen marking, laser marking, and electrolytic chemical etching. Data Matrix is the smallest barcode of size of all the barcode and can be printed in the real good easily. Generate & read Data Matrix barcode with Yiigo .NET Barcode Plugin.

Encoding Data & Length

Developed as alpha-numeric 2D/Matrix barcode, Data Matrix is capable of encoding:

ASCII: Double digit numerics, ASCII values 0 - 127, and Extended ASCII values 128 - 255
C40: Upper-case alphanumeric, Lower case and special characters
Text: Lower-case alphanumeric, Upper case and special characters
X12: ANSI X12 EDI data set
EDIFACT: ASCII values 32 - 94
Base 256: All byte values 0 - 255
Variable data length

Structure & Format Mode (Symbol Sizes)

A Data Matrix barcode consists of:

Timing pattern
Data characters
Finder pattern
Alignment pattern
Quiet zone

Data Matrix ECC200 symbol sizes (30 in all) can be divided into two categories:

24 square ones with sizes from 10x10 to 144x144 (even values only) not including quiet zones
6 rectangular ones with sizes from 8x18 to 16x48 not including quiet zones

Structure Append

Up to 16 ECC 200 symbols may be can be divided & reconstructed into one format. If the users want to create 3 pieces code into 1 barcode, the first thing is to set SymbolCount to 3, and then set the first SymbolIndex 1to 0; then set SymboleCount to 3, the second SymbolIndex to 1â¦remember the SymbolIndex is started with 0.

GS1 Compatible Data Matrix

For its ability to encode GS1 System data structures and offers other technical advantages, the GS1 System adopted Data Matrix barcode as one of the GS1 barcode. However, Data Matrix ISO version ECC 200 is the only version that supports GS1 System data structures, including Function 1 Symbol Character. Data Matrix Error uses Reed-Solomon error correction, and this feature helps correct for partially damaged symbols.
