Arches Platine works perfectly for processes such as Cyanotype, Platinum Palladium, Albumen, VanDyke Brown, Salted Paper, and Kallitype.
It is a Natural Bright White with a very hard surface sizing. Do not use tween or water before coating as this paper does not need any surfactant and will absorb the chemistry very readily.
Each sheet will have the Arches Platine watermark and 4 deckled edges.
