printing-out paper

Printing-out paper is a type of photographic paper coated with a silver halide gelatin emulsion. Unlike developing-out paper, the image on printing-out paper is visible immediately upon exposure to light, without the need for a separate development step. The processing of prints, whether on printing-out paper or developing-out paper, typically involves development, an intermediate rinse, fixing, and washing. However, some modern photographic papers incorporate chemicals within the emulsion that allow for dry processing through heating, or rapid processing in specialized machines. Contact printing, a simple method, involves placing the negative and printing paper together in a frame and exposing them to light, resulting in a print the same size as the negative.1234
