Bar Codes Chapter 8
8.1.24 Aztec, TCI 52
Aztec is a high density 2 dimensional barcode that can encode up to 3750 characters from
the entire 256 byte ASCii character set. Aztec also has the potential to use less space than
other matrix style barcodes because it does not require quiet zones.
The D193 command is used to receive and process the Aztec barcode with the elements
discussed below.
Once the Aztec barcode data is entered and processed, the barcode image may be placed
using the normal format field by using a TCI of 52.
The sample below shows how to generate a data matrix symbol:
^D193 <---------------------------------Start of Aztec Data
0 <----------------------------------------Size
0 <----------------------------------------Minimum error correction
0 <----------------------------------------Mode
:0123456789^\<---------------------- Data to encode
^D57
2,1280,300,19,38,7,2,1,44,0,0
1,640,100,1,52,1,0,4,10,10 <---------- Multiplier (10, 10); TCI 52
1,640,25,11,7,10,0,4,2,2,,,,,0
^D56
^D2
Aztec
^D3
NOTE: MULTIPLYING THE BARCODE GENERATED.
The barcode generated is based on a single dot width. For the barcode to be visible and to
scan properly, a reasonable multiplier must be used. Typical values for a multiplier are 8-
10. This is accomplished in the LDS1 format above on the line: 1,300,300,1,52,,,,10,10
Size - 0
This parameter is used to set the size the Aztec code to be generated. A value of "0" will
generate an automatically scaled Aztec. The overall size of the barcode is controlled by the
Size and by the formats X and Y multiplier values.
