Fluorescent print on the 1000-krone banknote

On the 1000-krone note there is an invisible paintbrush to the left of the portrait of Edvard Munch. It is only visible when the note is exposed to ultraviolet light. Fibres in the paper and a narrow strip on both sides of the holographic foil strip will also reflect the light.
