Pigment prints are guaranteed not to fade for 150-200 years. They are printed on Hahnemuhle “William Turner” fine art cotton rag paper and are mounted on medium density board or aluminium. Prints are sprayed with Hahnemuhle’s own fixative anti-UV spray. It is not necessary to put them under glass, indeed in my opinion they are best without, that way they are lighter and there are no reflections. They are highly water resistant and are quite suitable for putting in humid places such as bathrooms.
