Posters, magazines or booklets that have been printed with the risograph should not necessarily be stored under the influence of direct sunlight. Although the colour appears to be extremely durable due to its rich ink coverage, the paper can stain after intensive sun exposure. It should also be assured that the sheets are stored in a dry environment without excessive humidity. The risograph could easily work in such an environment, however, it can negatively affect the sheets. Store them in a shelf at a sufficient distance to a window front is therefore strongly recommended, even better is keeping them inside a cabinet that is not reached by daylight at all.
