FDT - What is a traceability code?

Question
The FDT prompts me to add a traceability code to my form - what is that and what am I suppose to enter?

Answer
The traceability code must manually be added on all pages enabling Anoto functionality, to keep track of the pattern and the printing. The code contains 3 parts:

1. a pattern identity code
2. a code for the certified printer (provided by the print shop; for qualified printers this part should be "090" and "999" for non-qualified printers
3. (optional) a batch number (if forms are printed by a printing shop, this will be provided by them)

So a traceability code can, for example, look like this: TC 78.090.111
