As an uncoated fine art paper, Platinum Rag from Hahnemuhle is ideal for platinum printing as well as a variety of other non-traditional photographic printing techniques, such as palladium, Van Dyke, cyanotype, and salt prints. It is acid free with no optical brightening agents and is free from alkaline buffering. This makes it easy to coat and clear. This paper is capable of displaying images with an excellent tonal range and very deep blacks.
