Фотографическая печать: процессы и материалы.

Production of an image on photosensitive paper

Photographic printing is the process of producing a final image on paper for viewing, using chemically sensitized paper. The paper is exposed to a photographic negative, a positive transparency (or slide), or a digital image file projected using an enlarger or digital exposure unit such as a LightJet or Minilab printer. Alternatively, the negative or transparency may be placed atop the paper and directly exposed, creating a contact print. Digital photographs are commonly printed on plain paper, for example by a color printer, but this is not considered "photographic printing". Following exposure, the paper is processed to reveal and make permanent the latent image.

Kodak Panalure is a panchromatic black and white photographic printing paper. Panalure was developed to facilitate the printing of full tone black and white images from colour negatives – a difficult task with conventional orthochromatic papers due to the orange tint of the film base. Panalure also finds application as paper negatives in large format cameras. It is generally not suitable for conventional black and white printing, since it must be handled and developed in near complete darkness. Kodak has announced that it will no longer produce or sell this product. However, as of 2006, it is still available from various online retailers.

Silver mirroring, or "silvering", is a degradation process of old black and white photographic prints caused by conversion of the black silver oxide to silver metal. This results in a slightly bluish, reflective patch in the darkest part of a print or negative when examined in raking light. It often indicates improper storage of the prints.

Ilfochrome paper uses the dye destruction process to produce prints from positive transparencies. The colour dyes are incorporated into the paper and bleached during processing. Ilfochrome, EP2 and Type R print papers and chemicals are no longer in production.
