In 1661, Sweden's first banknotes were produced by Stockholm Banco which were used as credit notes for its customers. These notes soon became worthless, however, when Stockholm Banco went bankrupt in 1668, and banknotes were subsequently prohibited.

Banknotes received a second chance in 1701 when the predecessor to Sveriges Riksbank started handing out transportsedlar, notes that worked in a similar way to modern cheques. These notes were easily forged, since the paper used for the production of the notes was imported, and these transports were often hijacked. In order to combat this, King Adolf Frederick ordered the construction of a proper paper production facility on the grounds of present-day Tumba Bruk on 23 June 1755. Paper production on a smaller scale had been going on since 1750.^[2]
