photographic printing paper

Photographic printing paper is a light-sensitive material used in photography to create a visible image from a negative. The process typically involves projecting an image from a photographic negative onto this paper, which has a silver halide emulsion similar to photographic film.12

After exposure, the paper undergoes development, where the exposed silver halide is converted into metallic silver, forming a positive image. This is followed by fixing to remove undeveloped silver halide and washing to create a permanent print. Printing papers come in various grades to accommodate negatives of different contrasts, and can also feature different surface textures and image colors. Modern printing papers often use a resin-coated base for efficient processing.23
