The Norwegian Central Union of Book Printers (Norwegian: Norsk Centralforening for Boktrykkere, FFNB) was a trade union representing typographers and those in related trades in Norway.
It was initially named the Norwegian Central Travel Fund for Book Printers, but adopted its better-known name in 1885.
In 1889, it led a lengthy strike in Oslo, after which it adopted the form of a modern trade union.
It later affiliated to the Norwegian Confederation of Trade Unions.
[2][3] In 1957, it renamed itself as the Norwegian Union of Typographers.
