Clean water, natural fibres, first-rate expertise in paper production and absolute quality awareness have formed the foundation of Hahnemühle success for over 435 years. Using precious resources such as water, fibres and energy carefully and responsibly is a matter of course for Hahnemühle.

The water Hahnemühle uses to produce our valuable FineArt papers comes straight from the source and is set apart by its particularly high level of purity, meaning it requires no chemical treatment whatsoever. Even at the end of the production cycle, the wastewater has not been contaminated with pollutants and is returned to the river as high-quality water.
