Module Size
This option sets the size of the modules that form the QR code. The modules are squares, so
if you select a value of 0.353 mm, the modules in the QR code are 0.353 mm by 0.353 mm. If
you increase the module size, the size of the QR code is increased.
Version
This is like the Size option for a Data Matrix field. There are 4 version options from 'Version
1 - 21x21' (that is, 21 modules by 21 modules) to 'Version 4 - 33x33' (33 modules by 33
modules). Each higher version number contains an additional four modules per side.
Table 6-12 shows the maximum version number allowed by each module size.
Module size (mm)

0.425

0.595
If the height of the QR code is more than the height of the message style, a warning message
is displayed. If the QR code is large, the field can cover the displayed text. Move the field or
the text to remove the problem.
Error Correction
A QR code can use an error correction capability to restore data if the code is dirty or
damaged. There are four error correction levels. A higher level of error correction decreases
the storage capacity that is available.
You can select one of the following levels of error correction:
•
Level L (Low)
•
Level M (Medium)
•
Level Q (Quartile)
•
Level H (High)
The default setting is Level L.
Maximum version
4 (33 modules by 33 modules)
3 (29 modules by 29 modules)
2 (25 modules by 25 modules)
1 (21 modules by 21 modules)
