Data Matrix code is 2D type of code used at most in industry for marking different small parts due to its small size and high reliability. Data matrix codes are made of square dark and light cells with matrix dimensions from 10×10 to 144×144. Encoded information is a string containing characters or numbers. As more data is encoded in the symbol, the number of cells is increased. Data size varies from a Additionaly data matrix code offers wide reading angles and high realibility due to error correction algorithm. Code damaged up to 30% can be reconstructed as*uming the matrix if DMC can be properly located. Defines the smalles cell in data matrix code. Modul size has to be made out of at least 2×2 printed dots for bigger realibility. Also Bottom and left side of Data Matrix code refers to finder pattern. The L pattern is used locate and orient the symbol. Finder pattern is also Dashed line positioned on upper-right side gives the reader information about Data Matrix code size. The sizes vary from 10×10 up A quiet zone is the area around Data matrix code, that does not contain any information. Quiet zone is separating DMC from its surroudings and should be at least one module wide. Using width of two module sizes is a good engineering practice. Data area is boardered by finder pattern and timing pattarn. With selected position of dark and white cells, the desired information is Size of data matrix code depends on the amount and type of information we want to encode. Type of data is important because encoding ASCII symbols is more complex as enconding only numerical values. When type and size of data is defined, size of matrix code depends directly on choosen modul width. With decresing modul size, the requirements for readers are increased. Let us say that data matrix code is printed with resolution 300 dpi and one cell is represented with 4×4 dots. This results in modul size of 0.34mm.  The following table represents data matrix code sizes and amount of data encoded with modul size 0.34mm.
