Datamatrix

2D Datamatrix marking is commonly used for Direct Part Marking (DPM) of machine-readable 2-D codes. The main purpose of 2D Data Matrix marking on parts is to enable automated reading of marks, which may be verified throughout the lifespan of the part. The advantage of 2D marking is traceability, improving manufacturing efficiency, quality control, and inventory management. 2D Data matrix marking satisfies a number of industry specific and governmental requirements, including U.S. Department of Defense UID (Unique Identification). The process involves permanent marking of the UID codes, verifying the readability of the code, and then reading the code during manufacturing and life of the part.

• Datamatrix Classification

Datamatrix is a 2D barcode symbology with very high data density. Datamatrix symbols are printed in square or sometimes rectangular patterns. Each dot of a DataMatrix symbol represents a bit. This is in contrast to linear bar-codes, where the information is encoded in the ratio of the bars or spaces to each other. Usually a black dot in a Data Matrix symbol is equivalent with the bit-value 1, but Datamatrix may also be printed white on black.

• Application Areas of Datamatrix

DataMatrix is used for encoding large amounts of data. It is mainly used in Europe and in the United States. The dominant application areas are through dot-peen and laser marking - in the aerospace, electronics, and automotive industries. A user can scan or decode this DataMatrix using a built-in camera and suitable decoder software.
