This unique black and white paper features a 100% cotton-fiber fine art base and is 100% acid-free. You can tell this 290 g/m² paper is unique from the moment you get your hands on it. This paper, made by Hahnemühle FeinArt GmbH, is enhanced by Harman Technology by means of a multigrade variable-contrast emulsion. This tried and tested coating saves the user from having to learn special processing techniques. Develop, stop and fix as you would Multigrade IV FB papers. The paper is available in 7 contrast grades between 00 and 5 and can be exposed just as any other multigrade variable contrast paper. If you want to process large sheets, the heavy base aids you when handling the sheets in developing trays.
