Data Matrix Marking

Data matrix marking is a process used to create a two-dimensional pattern of white and black squares. Much like a barcode, the marking can be scanned and interpreted by a computer to decipher the information contained in the marking. Data matrix markings are capable of containing up to 2335 alphanumeric characters within a 144 x 144 matrix. A data matrix code is recognized by a finder pattern and a timing pattern. The finder pattern is an 'L' of black squares on two adjacent edges of the pattern, while the timing pattern is represented by alternating white and black squares on the two opposite edges. The finder pattern is used to locate the pattern while the timing pattern provides the size of the code.
