<p>A known non-contact making printing process is used for the printing of forms, bank notes or packing materials. The known process may be an ink jet process, a magnetic process, an electrostatic process, or a light beam process. The invention is useful for printing bank notes because the non-contact making processes are pre-programmable so that security features of the print can be changed from time to time to improve safety against forging.</p> |
