DataMatrix is a two-dimensional
(2D) barcode symbology which can store from 1 to about 2,000 characters.
DataMatrix ECC200 version supports advanced encoding error checking and
correction algorithms (reed-solomon). Those algorithms allow the recognition of
barcodes that are up to 60% damaged.
DataMatrix is being used to encode product and serial number
information on electrical rating plates; to mark of surgical instruments in
Japan; to identify lenses, circuit boards, and other items during
manufacturing.
Barcode Professional supports all DataMatrix Formats, ECI (Extended Channel Interpretation), GS1 FNC1, Special functions like Reader Programming, Macro 05/06 and Structured Append symbols. The data represented in the symbol can be compressed using one of following encoding modes:
-
Auto: This mode will automatically switch between Data Matrix code sets to encode the specified value.
-
Ascii: it is used to encode data that mainly contains ASCII characters (0-127).
-
C40: it is used to encode data that mainly contains numeric and upper case
characters.
-
Text: it is used to encode data that mainly contains numeric and lower case
characters.
-
Base256: it is used to encode 8 bit values.
Sample of a DataMatrix Barcode
In order to get a DataMatrix barcode image, please follow
these steps:
-
Set the Symbology property to DataMatrix.
-
Set the DataMatrixEncoding property.
-
Set the DataMatrixFormat property.
-
Setting up dimensions and quiet zones:
-
Set the DataMatrixModuleSize property (Value is expressed in Inches)
-
Set the QuietZone property (Value is expressed in Inches)
-
Set the Code property with the value to encode.
-
If desired, you can use the tilde character "~" to specify special characters
in the input data. To do that you must set the DataMatrixProcessTilde property
to True. Read more about how it works.
When working with DataMatrix tilde processing keep in mind the
following rules:
-
~1: is used to represent the FNC1 code
-
~2: DEPRECATED! Use new Structured Append properties!
-
~3: is used only at the very beginning of the symbol for the reader programming purpose. It cannot be used with Structured Append feature!
-
~5: is used only at the very beginning of the symbol for MACRO 05. The header [)> + ASCII 30 + ASCII 05 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards. It cannot be used with Structured Append feature!
-
~6: is used only at the very beginning of the symbol for MACRO 06. The header [)> + ASCII 30 + ASCII 06 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards. It cannot be used with Structured Append feature!
-
~7NNNNNN: is used to specify the Extended Channel Interpretation (ECI) and NNNNNN is a value between 000000 and 999999. Default is ECI 000003 which represents the ISO 8859-1 Latin Alphabet No. 1
-
~dNNN: is used to represent a byte value in decimal notation. NNN must be a numeric value ranging from 000 to 255
-
~hXX: is used to represent a byte value in hexadecimal notation. XX must be a hexadecimal value ranging from 00 to FF
