Technical Specifications - DataMatrix
The Datamatrix symbol is an ISO international standard (IEC 16022). You are allowed to use it within your applications.
The Datamatrix code is a 2D barcode that can encode a large amount of information within a square or rectangle symbol. All 256 characters can be encoded.
You may use multiple symbols to spread your information in order to create a bigger message.
This barcode contains a way to detect and correct errors based on the Reed Solomon algorithm. The recovery rate is automatically defined by the barcode size.

Details
Datamatrix barcodes are separated into regions. Smaller barcodes contain only 1 region, but barcodes 32x32 and bigger contain 4, 16, or 36 regions.

There are many types of encoding Datamatrix can support.
Consider staying in one type of encoding instead of switching back and forth between encodings. This will allow your barcode to stay smaller because it takes a certain amount of bits to switch between encodings. Barcode Bakery will try to generate the smallest barcode possible when you provide data to the parse method.
For instance, it is preferable that you write only lowercase letters or capital letters but not switch back and forth between those two letter types.
The table below represents the bits per character depending on the encodation scheme.
Encodation scheme | Characters | Bits per data character |
---|---|---|
ASCII | Double digit numerics | 4 |
ASCII values 0 - 127 | 8 | |
Extended ASCII values 128 - 255 | 16 | |
C40 | Upper-case alphanumeric | 5.33 |
Lowercase and special characters | 10.66 | |
Text | Lowercase alphanumeric | 5.33 |
Upper-case and special characters | 10.66 | |
X12 | ANSI X12 EDI data set ([A-Z0-9], *> and <CR>) | 5.33 |
EDIFACT | ASCII values 32 - 94 | 6 |
Base 256 | All byte values 0 - 255 | 8 |
Our barcode generator follows the ECC 200 standard, which is recommended by the ISO standard.
