The R-400 has been firmly established in
government and private security printing
companies when it comes to the later
numbering and coding of small and
medium-sized series of high-security
products, such as passports, bank notes
and similar documents.
Combined with the numbering heads of
the SU series, it is possible to imprint
numberings using standard and special
engravings, as well as barcodes.
Manually-adjustable and automatic-
counting numbering machines are used
as print carriers. Depending on the print
head, printing inks and carbon ribbons with
additional security features such as UV
fluorescence or indelible ink penetration can be used in addition to standard printing inks and ribbons.
The product to be numbered is simply placed by hand, then printing is triggered using a hand or foot switch.
For optimal printing results, the pressure and the intensity of the inking can be controlled directly by
potentiometers. Adjustable guides ensure consistent positioning
of the products being numbered.
Numbering and imprinting heads of the series SU
In combination with the numbering heads of the SU series, numberings in Gothic, CMC 7, E 13B and OCR
as well as barcode, signatures and logos can be printed.
Whenever simple numbering is required, the SU1 numbering head, proven thousands of times in use, can
demonstrate its performance. With the extremely low printing costs, it is unrivalled in its field of application.
Oil-based stamping inks are used for printing on absorbent materials made from paper. Used in combination
with steel rotary numbering machines, the controllable pressure setting of the SU printing heads provides
easy crash numbering of NCR form sets.
With the sophisticated letterpress inking unit, the Radus SU2 numbering head is an impressive direct
development of the tried-and-tested SU1. Two inking rollers, in combination with two oscillating distributing
rollers, allow the use of viscous letterpress inks and inks with security features, such as UV fluorescence or
indelible ink penetration, which make the SU2 unique in this profession.
The letterpress inking unit allows the imprinting of high-quality Gothic and OCR numbering, as well as
barcodes, in all types of document. In addition, when using security printing inks, the SU2 is ideal for
numbering passports and visa documents, and for later numbering of bank notes. Rotary barcode and
numbering machines made from steel are used as printing carriers; combinations of numbering machines
and texts are also possible, in addition to standard and special engravings.
The SU4 numbering head was developed for numbering and coding using special carbon ribbons. The ink
on a carrier film is transferred cold, directly to the paper, using pressure from the numbering unit. An
adjustable transport mechanism then advances the film precise.
The numbering head processes carbon ribbons for OCR and MICR numbering, as well as carbon ribbons
with additional security features, such as UV fluorescence yellow / green and indelible red ink penetration -
bleed through. Replacing the rotary numbering machine with magnetic print blocks enables the imprinting of
signatures and logos. The numbering head can also be supplied in a pneumatic version with a heating unit
to be used with hot-stamping foils.
