RC paper, or resin-coated photographic paper, is printing paper that features a plastic or resin coating over the paper base. This coating speeds up processing by reducing absorption of chemicals and also provides a high-gloss or semi-matte finish for the final print.
RC paper is widely used in darkroom and professional printing environments because it dries faster, resists curling, and produces sharp, vibrant images. Its durability and ease of handling make it a preferred choice for photographers seeking efficient workflow and high-quality prints.
