Name Description
1 Quiet Zone Quiet zone is necessary to scan the code. The data matrix needs one module
surrounding the code.
2 Timing Module Has the alignment pattern with black and white modules. It provides easy recognition of
data modules.
3 Border The orientation of data matrix can be detected by the alignment pattern with L-shaped
lines.
4 Data Area The area where data are coded. The black unit module (the minimum unit of code) is
called as “mark module” and white as “space module”.
When creating mark/space module patterns with the Font Maker, the entire character
image is the module pattern area of data matrix code.
