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.
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.
In our example we need to choose dimension 14×14 which is capable of storing string or 16 numbers or 10 ASCII characters.
This just recieved from the bugged phone line of the Wachowski brothers....
We showed his body being burned and his ashes being shot into the sun.
Let us say that data matrix code is printed with resolution 300 dpi and one cell is represented with 4×4 dots. The following table represents data matrix code sizes and amount of data encoded with modul size 0.34mm. But we've talked to Keanu and he swears he can drop 50 pounds and- ANDY Dammit, Joel. JOEL You're breaking up here, I'm almost out of my service area. It'll be tough, but I told them you were my guys and you could do it. JOEL Also - I'm blueskying with Gabriel and he suddenly says -and you will LOVE this- that if the movies were only a half hour long, we could have like thirty showings a day. We even had that scene at the end where God himself came down from Heaven and declared that Neo and Trinity would never, ever, ever return lest all of existance be unmade. Carrie-Ann is close to signing- ANDY Joel, I'm getting death threats from fans. As more data is encoded in the symbol, the number of cells is increased.
Data size varies from a few bytes up to 1556 bytes.
Additionaly data matrix code offers wide reading angles and high realibility due to error correction algorithm.
