6.2 2D Symbologies
6.2.1 Aztec Code
Symbology number: 92
Valid characters: ASCII 0-127 + ISO 8859-1
Quiet zone: left/right/ top/bottom: 0X
Module width: --
Print ratio: 1:1
Ratio format: 1B:1S
Default check digit: Automatic (symbology specific).
Size: --
Aztec Code can encode from small to large amounts of data with user-selected percentages of error
correction. The symbol size adjusts automatically depending on the amount of input data.
The input data is always analyzed and the appropriate encoding mode is chosen automatically.
Mode switching is done as required to produce the most efficient encoding.
6.2.1.1 The Maximum Data Capacity of Aztec Code
The Aztec Code specification defines the following:
Numerical data only: 3832
Bytes: 1914
Text characters: 3067 (only uppercase letters used [A..Z])
If you mix the character types the maximum data capacity cannot be predicted exactly (due to
internal compression and character set switching - this is by design).
If you use a combination of digits and text (lower & uppercase letters) the maximum data capacity
would be about 2500 characters - but this can vary due to your input data. If you want to encode
large data amounts we recommend using only capital letters or multiple symbols (structured
append).
6.2.2 Codablock F
Symbology number: 74
Valid characters: ASCII 0-127 + ISO 8859-1
Quiet zone: left/right/ top/bottom: 10X
Module width: X>=0.19mm
Print ratio: 1:2:3:4:1:2:3:4
Ratio format: 1B:2B:3B:4B:1S:2S:3S:4S
Default check digit: Automatic (symbology specific).
Size: 2 - 44 rows; 4 - 62 characters per row
Codablock F is de facto a “stacked” Code128 symbology. It is based upon Code 128 - each row is
a single Code 128 symbol extended with row indicator information and additional check digits. The
UCC/EAN format indicator is supported.
