Security Document Protection with Serial
The unique identification of a document can be guaranteed through the
use of an individual serial number. Depending on the use, products such
as passports, bank cheques and bank notes can be uniquely identified
using sequential numbering.
For this purpose, visually readable numbering in Gothic can be used, for
example, as well as machine-readable MICR/OCR numbering.
The inclusion of a mathematical formula such as the Modulo10 check
digit offers simple protection against forgeries. In addition, in security-
relevant ID documents, special black numbering that fluoresces yellow /
green under UV light, as well as indelible red penetrating (bleed through)
numbering can be used. UV fluorescence allows simple, visual
authentication using a UV lamp, and penetrating ink is an effective
protection against manipulation.
Mechanical numbering is certainly the best known form of numbering in
the world. Here the printing ink is transferred directly to the document
using an engraved numbering machine. After each printing cycle, the
mechanism of the numbering machine advances one digit. The simple
application of security inks and special carbon ribbons make the use of
mechanical numbering indispensable in security printing, and the
achieved offset print quality is often unsurpassed.
Well-known examples can be found on:
Business forms and NCR form sets, as well as bank notes, bank
cheques, schengen visa, passports and related identification documents
in the security area.
