In the field of digital printing, there are classic mass-market applications like those used in the letter distribution centers of large banks, insurance companies, and telecommunications companies. These include customized postal items, such as invoices or account statements.
These documents must be individually identified and bundled together correctly before being inserted into envelopes. To do this, each individual sheet is given a Data Matrix code that contains a unique data record. Every sheet can then be accurately assigned in each subsequent processing step in the letter distribution facility.
