Most stamp collectors even those not interested in printing techniques I'm sure have heard of the term GIORI.
The first US stamp printed by the Giori Press was the "Old Glory" Flag stamp issued in 1957
Leafing through Scott's US pages from the fifties to the seventies one sees GIORI PRESS PRINTING over and over.
It is the most popular printing process press in the world.
In 1947, at the age of 34, Gualtiero Giori aided by the patents and ideas of the Frenchman Serge Beaune
(who by the 1930s had already developed a process for 3 colour Rotary Recess Printing)
produced and started marketing the revolutionary 6-colour intaglio printing press.
This machine was sold to the Central Bank of Argentina and installed in the Casa de la Moneda in 1949.
It was the very first machine in the world specially conceived to print banknotes in a variety of color.
Argentina did issue a 2 colour engraved stamp Scott 585 in 1949 which I believe was also printed by this Giori Press.
In 1952 he established the "Giori Organization".
The company became the first in the world to design, produce, and supply machinery and
specialized equipment for printing banknotes and security documents.
In the same year the Swiss/Italian security printing specialist Gualtiero Giori enterrd a strategic partnership with
Koenig & Bauer AG,Würzburg, Germany
First multicolour intaglio press for printing banknotes
Koenig & Bauer handled press engineering and manufacturing, along with the attendant security and logistics systems.
Giori company focused on international sales and distribution, customer advice, the development of counterfeit-proof banknotes
and cross-platform process technology.
This highly successful division of labour enabled the two parties to dominate the sector.
1965 Giori enters into a Switzerland-based joint venture called De La Rue Giori.
Within a few years Koebau-Giori-DeLaRue presses were printing around 90 per cent of the world's banknotes.
2001 Koenig & Bauer AG (KBA) acquired its long-time business partner, De La Rue Giori.
2011 KBA-Giori S.A. renamed KBA-NotaSys SA.
