Handling and Storage of Microfilm Supplies

  • Handle, expose and process under gold fluorescent lights.
  • Normal room illumination is suitable for short periods.
  • Open the package only when the film is ready to be used, and return the unused film to light-protective storage when duplicating equipment is shut down.
  • Store unopened packages of the film for up to six months at 21°C (70°F) at 50% relative humidity or below. For longer storage,
  • keep packages at the same humidity at 10°C (50°F) or lower.
  • To avoid fogging and loss of density, avoid prolonged exposure to sources high in ultraviolet radiation, such as sunlight or white fluorescent light.
  • To avoid pre-development, avoid exposure to high temperatures and ammonia fumes or other alkaline Contaminants.
