These papers have names ending in -chrome, as in Ilfochrome. Color reversal films are meant for enlarging slides on transparency in a positive-to-positive process. These papers will have names ending in -color, as in Agfacolor or Kodak’s Ektacolor. ![]() Color negative paper is meant for the negative-to-positive process. Choose the appropriate color photographic paper for the process you are using: either Color Negative Paper or Color Reversal Film. Unlike film, color paper has no orange mask. Like color film, color paper consists of three emulsions, each one responding to one third of the spectrum. Allow the paper to return to room temperature before printing. Fingerprints are more likely to show up on glossy paper. If storing unused paper for long periods, seal tightly and place the box in a refrigerator or other cool location. Do not bend (paper will crease) or touch the image area (fingerprints will be permanent). Fogged paper is unusable as it produces a gray or colored veil in affected areas. Color paper that is accidentally exposed to light will be fogged. ![]() Make sure to keep paper inside the sealed bag and box at all times, especially when printing in a community lab where someone might turn on the white lights without warning. All photographic papers come packaged inside a light-proof black plastic bag inside a cardboard box. As color papers are sensitive to all lights, they must be handled with care in a pitch-black darkroom or with very dim and obscure amber safelights. Color papers are made up of three emulsion layers, each sensitive to a different wavelength of light. Emulsion is sensitive to different waves of light depending upon whether the paper is meant for color or black and white printing. Photographic printing papers are coated with light-sensitive emulsion.
