The Typographical Association was founded in 1869, focusing its attention on discussions on the development of the trade, and establishing a library for members, in Copenhagen.
In 1876, Jensen did lead a strike for improved pay but, without links to other labour movement organisations, the union was unable to sustain the action.
The strike was lost, members of the union fell below 100, and Jensen resigned.
However, this loose federation made no progress, and in 1965, the typographers resigned from the LO and the cartel.
It rejoined LO in 1971, forming a new Graphics Cartel in 1972, but again this ran into disputes, and was dissolved in 1980.
